III. Executive Summary

    When writing regulations that set technical standards, the Coast
Guard relies as much as possible on existing industry consensus
standards. Doing so minimizes proliferation of differing standards and
complies with the National Technology Transfer and Advancement Act and
OMB Circular A-119. The legal method of directing

regulated entities to follow separately published standards is called
incorporation by reference (IBR). This notice of proposed rulemaking
(NPRM) proposes to update prior incorporations by reference, add a
limited number of alternative standards, and eliminate outdated or
unnecessarily prescriptive regulations in title 46 of the Code of
Federal Regulations (CFR) subchapter J.
    This proposed rule would update the standards incorporated by
reference (IBR) in both 46 CFR 110.10-1 and all of the sections in
subchapter J that reference the updated IBR standards. More
specifically, this proposed rule would incorporate the more recent
editions of many standards, incorporate by reference additional
standards for certain topics, and remove IBR standards that are no
longer actively used by industry. Due to technological advances, it is
necessary to update the current standards to ensure modern technologies
are addressed in the regulations. In addition to updating the IBR
standards, we propose the following four changes to subchapter J.
    First, this proposed rule would eliminate the prescriptive
requirements in 46 CFR 111.12-1(b) and (c) for generator prime movers.
In accordance with 46 CFR 58.01-5, these generator prime movers would
continue to be required to meet standards of the American Bureau of
Shipping (ABS) Steel Vessel Rules.
    Second, this proposed rule would simplify the electrical cable
construction requirements in subpart 111.60 so they are similar to the
classification society requirements currently accepted without
supplement under the Coast Guard's Alternate Compliance Program.
    Third, for classifications of hazardous locations in subpart
111.105, this proposed rule would accept the International
Electrotechnical Commission's (IEC) 60092-502 as an alternative
classification. This is an internationally accepted standard and we are
not aware of any notable casualty history attributed to its use as
compared to vessels complying with the current applicable U.S.
regulations for classification of hazardous locations.
    Fourth, this proposed rule would amend 46 CFR 112.05 to allow the
use of an emergency generator in port. This optional capability to use
emergency generators in port would be acceptable if a set of additional
safeguards, approved by the International Maritime Organization (IMO)
in 2005 are provided to ensure the availability of emergency power.
    The following table provides an overview of the types of proposed
changes and the affected sections.

------------------------------------------------------------------------

IV. Basis and Purpose

    The legal basis of this proposed rulemaking is section 1333(d) of
Title 43, United States Code (U.S.C.), sections 3306 and 3703 of Title
46 U.S.C., and the Department of Homeland Security (DHS) Delegation No.
0170.1. The provisions of 43 U.S.C. 1333(d) grant the Secretary of the
Department in which the Coast Guard is operating the authority to
promulgate and enforce regulations with respect to lights and other
warning devices, safety equipment, and other matters relating to the
promotion of safety of life and property on artificial islands,
installations, and other devices. Section 46 U.S.C. 3306(a)(1)
authorizes the Secretary to prescribe regulations for the design,
construction, alteration, repair, and operation of vessels subject to
inspection, including equipment, appliances, propulsion machinery,
auxiliary machinery, boilers, unfired pressure vessels, piping, and
electric installations. Additionally, 46 U.S.C. 3703 grants the
Secretary authority to regulate the construction, alteration, repair,
maintenance, operation, and equipping of vessels, that may be necessary
for increased protection against hazards to life and property, for
navigation and vessel safety, and for enhanced protection of the marine
environment. These authorities have been delegated to the Coast Guard
by the DHS Security Delegation No. 0170.1(II)(92)(b).
    The purpose of this proposed rulemaking is to update the standards
that are incorporated by reference in 46 CFR subchapter J, which
provide detailed specifications for electrical equipment used by
vessels. Newly published editions of the international standards
referenced in subchapter J address new technologies and changes in best
practices. The Office of Management and Budget (OMB) Circular A-119
states agencies should undertake a review of the standards incorporated
by reference every 3 to 5 years to remain current with technological
changes. OMB encourages reducing reliance on unique government
standards when an existing voluntary consensus standard would suffice.
This proposed rule follows the Circular by incorporating newer editions
of industry standards and reducing the reliance on unique Coast Guard
standards where industry standards are sufficient.

V. Background

    Title 46 CFR subchapter J contains the electrical engineering
regulations and standards applicable to vessels and required shipboard
systems regulated under subchapters D, H, I, I-A, K, L, O, Q, R, T, U,
and W of Title 46. A key component of subchapter J is the standards
that are incorporated by reference (IBR) in 46 CFR 110.10-1 and cross-
referenced throughout parts 110, 111, 112, and 113. The IBR section in
subchapter J was last amended by the 2015 final rule titled
``Electrical Equipment in Hazardous Locations'' (80 FR 16980, Mar. 31,
2015), but because of its limited scope, that rule did not update all
of the standards to reflect newer editions. Many of the IBR standards
have not been updated since 2008 when the Coast Guard issued the final
rule titled ``Review and Update of Standards for Marine Equipment'' (73
FR 65156, Oct. 31, 2008).
    Furthermore, the interim rule titled ``Offshore Supply Vessels of
at Least 6,000 GT ITC'' (79 FR 48893, Aug. 18, 2014) and the
``Electrical Equipment in Hazardous Locations'' final rule (80 FR
16980, Mar. 31, 2015) amended subchapter J by adding the hazardous
location regulations in subparts 111.106 and 111.108 for types of
vessels and facilities not covered under subpart 111.105. Vessels and
facilities regulated under 111.106 and 111.108 have a broader and more
current selection of IBR standards because there were more recent
standards to include with those rulemakings. This proposed rule would
amend subparts 111.105, 111.106 and 111.108 to ensure all vessel types
are offered the broadest and most current selection of IBR explosion
protection standards.
    Shipboard electrical systems are becoming increasingly complex due
to the development of power electronics and computer control systems.
In response, many of the standards incorporated by reference have been
superseded by newer editions to address the newer electrical equipment.
In some cases, the later editions reflect more modern technologies,
terminology, and practices that are already in use by industry.
Adopting newer versions of these standards would reduce the number of
equivalency requests from industry to the Coast Guard, which is
expected to produce cost savings. The incorporation of more recent
editions also ensures the latest industry practices and advancements in
technology are addressed in regulations.

VI. Discussion of Proposed Rule

A. Proposed Revisions to Sec.  110.10-1 Incorporation by Reference

    Currently, all of the standards that are incorporated by reference
in subchapter J are listed in Sec.  110.10-1. Within this section, the
Coast Guard proposes to update the technical standards to reflect the
more recent editions of the standards available to the public. We
encourage the use of these updated standards because they reflect the
best available technologies, practices, and procedures that are
recommended by consensus bodies and other groups with experience in the
industry. As the baseline upon which other standards, rules, and
equivalency requests are evaluated, it is important that subchapter J
incorporates up-to-date references.
    The class rules of the American Bureau of Shipping (ABS), in
particular, are incorporated by reference in multiple locations within
subchapter J and throughout 46 CFR Chapter I. It is important to note
that while these rules set the regulatory baseline or standard for
specific engineering systems and equipment, the Coast Guard also
designated several other authorized classification societies in
accordance with 46 CFR part 8. These classification societies are
listed on the Coast Guard website.\1\ The Coast Guard authorized the
listed classification societies to perform certain functions and
certifications using their respective class rules on vessels enrolled
in the Alternate Compliance Program. Vessels not enrolled in the
Alternate Compliance Program may propose using the class rules of an
authorized classification society as an alternative to the ABS class
rules incorporated by reference for particular engineering systems and
equipment in accordance with Sec.  110.20-1.

    \1\ See https://www.dco.uscg.mil/Our-Organization/Assistant-Commandant-for-Prevention-Policy-CG-5P/Inspections-Compliance-CG-5PC-/Commercial-Vessel-Compliance/Flag-State-Control-Division/ClassSocAuth/.
---------------------------------------------------------------------------

    Throughout Sec.  110.10-1, we also propose additional standards to
provide alternative compliance options, remove outdated standards, and
clarify existing requirements. Where applicable, this proposed rule
would also update the naming format, mailing addresses, phone numbers,
and URL addresses for the standards already incorporated by reference.
These updates will ensure that the standards are reasonably accessible
to the public.
    Following this paragraph, we list the standards we propose to
update, add, or delete in Sec.  110.10-1. Within each standard listed,
we describe the topics covered by the standard, the proposed changes to
the standard, any differences between currently incorporated IBR
standards, and a list of the subparts or sections that reference the
IBR standard. If this proposed rule does not propose any changes to a
standard that is

currently incorporated by reference, the standard will not be discussed
in the proposed revisions to Sec.  110.10-1. However, it will be
included, without change, in the proposed regulatory text that appears
at the end of this document.
     ABS Rules for Building and Classing Marine Vessels (ABS
Marine Vessel Rules), 2020. The ABS is a vessel classification society
that develops and publishes rules for the construction and maintenance
of ships and offshore facilities. Subchapter J references these rules
in numerous sections as an option for the design of certain systems
including generators, semiconductor rectifiers, and electric propulsion
systems. Specifically, we currently reference the 2003 edition in
Sec. Sec.  110.15-1(b), 111.01-9(b), 111.12-3, 111.12-5, 111.12-7,
111.33-11, 111.35-1, 111.70-1(a), 111.105-31(n), 111.105-39(a),
111.105-40, and 113.05-7(a). In 2020, ABS transitioned from the ABS
Steel Vessel Rules to the ABS Marine Vessel Rules. This allowed ABS to
consolidate several rules into one foundational rule. We propose to
incorporate by reference the 2020 ABS Marine Vessel Rules in the
aforementioned sections and additionally in the new proposed Sec.
112.05-7(c) related to use of emergency generators in port. The ABS
Marine Vessel Rules undergo an annual review and approval process by
ABS technical committees. The Coast Guard participates on these
committees, which are comprised of international experts with relevant
experience. Several of the sections of the ABS Marine Vessel Rules that
we propose to incorporate by reference have been individually updated.
For example:
    [cir] ABS Marine Vessel Rules 4-8-3/Table 2: This table specifies
minimum degrees of protection for electrical equipment. This updated
table contains several technical updates since 2003 edition, including
additional notes concerning areas protected by fixed water-spray or
water mist fire extinguishing systems, and equipment subject to water
splash.
    [cir] ABS Marine Vessel Rules 4-8-3: We reference this section for
generator construction requirements. The updated edition contains
technical updates to account for changes in technology since the 2003
edition.
    [cir] ABS Marine Vessel Rules 4-8-5/5.17.9: This section regarding
semiconductor rectifiers now requires a high temperature alarm.
    [cir] ABS Marine Vessel Rules 4-8-5/5.5: This edition contains
updates to propulsion generator requirements.
    [cir] ABS Marine Vessel Rules 4-8-2/9.17: This edition updates the
requirements for protection of motor circuits to address athwartship
thruster motor load alarms and more clearly defines the systems
requiring undervoltage release.
    [cir] ABS Marine Vessel Rules 4-8-3/5: This updated section
regarding switchboards and motor controllers contains additional cable
connection requirements, optional alternative creepage and clearance
distances, and additional requirements on battery and uninterruptible
power systems based on advancements in technology.
    [cir] ABS Marine Vessel Rules 5-10-4/3: This section regarding
roll-on/roll-off cargo spaces is now titled 5C-10-4/3. The new edition
made updates to ventilation requirements and to the tables of dangerous
goods.
    [cir] ABS Marine Vessel Rules 4-9-7/Table 9: This table regarding
equipment testing is now titled 4-9-8/Table 1. The updates to this
table reflect changes in technology and industry testing practices.
     ABS Rules for Building and Classing Mobile Offshore Units
(ABS MOU Rules), Part 4 Machinery and Systems, 2020. ABS also develops
and publishes rules for the construction and maintenance of mobile
offshore drilling units. Subchapter J references these rules in
numerous sections as an option for design of certain systems including
generator, semiconductor rectifier, and electric propulsion systems.
Specifically, we currently reference the 2001 edition in Sec. Sec.
111.12-1(a), 111.12-3, 111.12-5, 111.12-7(c), 111.33-11, 111.35-1, and
111.70-1(a). In 2020, ABS transitioned from the ABS Mobile Offshore
Drilling Units Rules to the ABS MOU Rules. This allowed ABS to
consolidate several rules into one foundational rule. We propose to
incorporate by reference the 2020 ABS MOU Rules. Like the ABS Marine
Vessel Rules, the ABS MOU Rules will undergo a regular review and
approval process by the ABS technical committees comprised of
international experts with relevant experience. ABS updated and changed
the title of several of the ABS MOU rules incorporated by reference in
these sections. For example:
    [cir] ABS MOU Rules 4-3-4 (renamed ABS MOU Rules 6-1-7): We
reference this section regarding generator construction requirements.
ABS made several technical updates since the 2001 edition to account
for changes in technology.
    [cir] ABS MOU Rules 4-3-4/3.5.3 (renamed 6-1-7/12): We reference
this section, for semiconductor converters requirements. ABS made
several updates to the standard due to changes in technology.
    [cir] ABS MOU Rules 4-3-4/7.1 (renamed 6-1-7/9.9): We reference
this section regarding bus bars and wiring requirements. ABS made
several updates to the section since the 2001 edition.

Breakers (over 1,000 Volts), 2008. This represented a complete
technical revision of the standard. IEEE subsequently revised it again
in 2018. We are proposing to incorporate by reference IEEE C37.12-2018
in Sec.  111.54-1 and further discuss this standard with the other IEEE
standards incorporated by reference.
     ANSI/IEEE C37.27-1987 (IEEE 331)--Application Guide for
Low-Voltage AC Nonintegrally Fused Power Circuitbreakers (Using
Separately Mounted Current-Limiting Fuses). We are proposing to remove
the reference to this standard in Sec.  111.54-1 because this guide was
replaced by IEEE C37.27-2015--IEEE Guide for Low-Voltage AC (635 V and
below) Power Circuit Breakers Applied with Separately-Mounted Current-
Limiting Fuses, 2015. We discuss this standard, IEEE C37.27-2015, with
the other IEEE standards incorporated by reference.
     ANSI/International Society of Automation (ISA) 12.12.01-
2015--Nonincendive Electrical Equipment for Use in Class I and II,
Division 2 and Class III, Divisions 1 and 2 Hazardous (Classified)
Locations. The purpose of this standard is to provide minimum
requirements for the design, construction, and marking of electrical
equipment or parts of such equipment for use in Class I and Class II,
Division 2 and Class III, Divisions 1 and 2 hazardous (classified)
locations. This newer edition of the standard would replace ANSI/ISA
12.12.01-2012 which the Coast Guard recently added to Sec.  111.108-
3(b) as part of a separate rulemaking titled ``Electrical Equipment in
Hazardous Locations'' (80 FR 16980, Mar. 31, 2015). Additionally, we
propose to include ANSI/ISA 12.12.01-2015 in Sec. Sec.  111.105-7(a)
and 111.106-3(b) as another certification option for electrical
equipment in hazardous location. The 2015 edition contains

minor technical changes from the 2012 edition.
     ANSI/ISA-60079-18--Explosive atmospheres--Part 18:
Equipment protection by encapsulation ``m'', Third Edition, 2012. This
standard gives the specific requirements for the construction, testing,
and marking of electrical equipment and parts of electrical equipment,
and for the designation of explosion-protected electrical apparatus
complying with IEC standards (Ex) components (which is part of an
electrical equipment module found in the European hazardous area
scheme) with the type of protection encapsulation ``m'' intended for
use in explosive gas atmospheres or explosive dust atmospheres. We
currently reference the 2009 edition of this standard in Sec.  111.106-
3(d), and the 2012 edition in Sec.  111.108-3(e). This proposed rule
would remove the ANSI/ISA-60079-18 references in Sec. Sec.  111.106-
3(d) and 111.108-3(e) because it has been withdrawn and replaced by UL
60079-18, a substantively similar standard. We propose replacing the
ANSI/ISA standard with UL 60079-18 in Sec.  111.106-3(d) and 111.108-
3(e).
     American Petroleum Institute (API) Recommended Practice
API RP 14F--Recommended Practice for Design, Installation, and
Maintenance of Electrical Systems for Fixed and Floating Offshore
Petroleum Facilities for Unclassified and Class 1, Division 1 and
Division 2 Locations, Sixth Edition, October 2018. This document
recommends minimum requirements and guidelines for the design,
installation, and maintenance of electrical systems on fixed and
floating petroleum facilities located offshore. We propose to reference
clause 6.8 of the document in Sec.  111.105-17. This clause provides
guidance on use of conduit, cable seals, and sealing methods. The
incorporation of this standard would add another wiring option in
hazardous locations.
     API RP 14FZ--Recommended Practice for Design,
Installation, and Maintenance of Electrical Systems for Fixed and
Floating Offshore Petroleum Facilities for Unclassified and Class I,
Zone 0, Zone 1 and Zone 2 Locations, Second Edition, May 2013. This
document recommends minimum requirements and guidelines for the design,
installation, and maintenance of electrical systems on fixed and
floating petroleum facilities located offshore. We propose to reference
clause 6.8 of the document in Sec.  111.105-17. This clause provides
guidance on use of conduit, cable seals, and sealing methods. The
incorporation of this standard would add another wiring option in
hazardous locations.
     API RP 500--Recommended Practice for Classification of
Locations for Electrical Installations at Petroleum Facilities
Classified as Class I, Division 1 and Division 2, Third Edition,
December 2012. This recommended practice provides guidelines for
classifying locations at petroleum facilities as Class I, Division 1
and Class I, Division 2 locations for the selection and installation of
electrical equipment. We currently reference the second edition (1997)
of this standard in Sec. Sec.  111.106-7(a) and 111.106-13(b). We
propose to reference the more recent, third edition (2012) in those
sections. The 2012 edition contains editorial changes, but the
technical content has not changed.
     API RP 505--Recommended Practice for Classification of
Locations for Electrical Installations at Petroleum Facilities
Classified as Class I, Zone 0, Zone 1, and Zone 2, Second Edition,
August 2018. The purpose of this recommended practice is to provide
guidelines for classifying locations Class I, Zone 0, Zone 1, and Zone
2 at petroleum facilities for the selection and installation of
electrical equipment. We currently reference the first edition, which
was published in 1997 and reaffirmed in 2013, in Sec.  111.106-7(a) and
111.106-13(b). We propose to reference the more recent, second edition
(2018) in those sections. This will not substantively change to the
requirements of those sections.
     American Society of Mechanical Engineers (ASME) A17.1-
2016/CSA B44-16--Safety Code for Elevators and Escalators, 2016. This
code covers the design, construction, operation, inspection, testing,
maintenance, alteration, and repair of elevators, hoists, escalators
and their associated parts, rooms, and spaces. We currently reference
the sixteenth edition (2000) in Sec.  111.91-1. We propose to reference
the more recent, twenty-first edition (2016) in that section. ASME
updated this standard based on changes in technology. The updated
standard addresses new types of elevators being used in the industry,
specifically wind turbine elevators and outside emergency elevators. In
addition, the standard contains new requirements to address a new
feature called ``Elevator Evacuation Operation'' that allows for the
use of elevators for occupant evacuation. Moreover, there are several
major changes to the standard that include seismic requirements,
updated maintenance control program requirements, and revisions
regarding qualifications for elevator inspectors. ASME A17 has been an
industry accepted standard since 1921. Although many of the changes to
the presently incorporated edition of the standard do not apply to
shipboard elevators, it is important that shipboard elevators meet the
updated provisions that do apply.
     ASTM International (ASTM) B117-19--Standard Practice for
Operating Salt Spray (Fog) Apparatus, 2019. This practice covers the
apparatus, procedure, and conditions required to create and maintain
the salt spray (fog) test environment. Where the Coast Guard's
regulations require material to be corrosion resistant it must meet the
testing requirements of this ASTM standard practice. We currently
reference the 1997 edition in Sec.  110.15-1(b). We propose to
reference the current 2019 edition. The 1997 edition has been
superseded by several subsequent editions. The testing specifications
in the 2011 edition are similar to those in the 1997 edition, but the
2011 edition is more detailed. For example, the impurity restrictions
are more detailed in section 8, the air supply requirements are more
specific in section 9, and the conditions in the salt chamber are more
precisely described in section 10. The 2016 edition added a warning
about the impact of water conductivity in section 4 while the 2019
edition added several minor but non-substantive explanatory sections.
Overall, the 2019 edition of this testing standard practice for
operating salt spray apparatus is very similar to the 1997 edition
currently incorporated, with minor improvements in the specifications
to ensure testing consistency and precision.
     ASTM F2876-10--Standard Practice for Thermal Rating and
Installation of Internal Combustion Engine Packages for use in
Hazardous Locations in Marine Applications, Reapproved 2015. This
practice covers the method of testing, rating and installing internal
combustion engine packages for use in hazardous areas in marine
applications. We currently reference the 2010 edition of this standard
in Sec. Sec.  111.106-3(h) and 111.108-3(g). We also propose to
reference the 2010 edition in newly proposed Sec.  111.105-28 regarding
internal combustion engines. This will ensure a consistent standard for
these installations on all vessel and facility types.
     Canadian Standards Association (CSA) C22.2 No. 30-M1986--
Explosion-proof enclosures for use in class I hazardous locations,
Reaffirmed 2016. This standard covers the details of construction and
tests for explosion-proof enclosures for electrical

equipment to be used in Class I, Division 1, Groups A, B, C, and D
hazardous locations and in gaseous mines. We currently reference the
1986 edition of this standard in Sec. Sec.  111.106-3(b) and 111.108-
3(b) and propose to incorporate the reaffirmed version therein. The two
versions are not substantively different. We propose to also reference
this reaffirmed standard in Sec.  111.105-7(a), regarding approved
equipment, as an additional compliance option. This will afford the
broadest and most current selection of IBR explosion protection
standards for all vessel and facility types.
     CSA C22.2 No. 213-16--Nonincendive electrical equipment
for use in class I, division 2 hazardous locations, May 2016. This
standard applies to electrical equipment for use in Class I and II,
Division 2 and Class III, Division 1 and 2 hazardous locations. We
currently reference the 1987 edition in Sec. Sec.  111.106-3(b) and
111.108-3(b). We propose to reference the 2016 edition in these
sections and also reference it in Sec.  111.105-7(a) concerning
approved equipment. This standard received a major revision since the
1987 edition based on advances in technology and changes to related
standards. It is an accepted national standard and one of several
available standards for nonincendive electrical equipment. Our
incorporation of this updated edition ensures use of latest industry
practices and including it in Sec.  111.105-7 will ensure that
standards are consistent for electrical installations on all vessel and
facility types.
     CSA-C22.2 No. 0-10--General requirements--Canadian
Electrical Code, Part II, Reaffirmed 2015. This standard covers
definitions, construction requirements, marking, and tests of a general
nature that applies to all or several of the individual standards of
the Canadian Electrical Code. We currently reference the ninth edition
of this standard in Sec. Sec.  111.106-3(b) and 111.108-3(b). We
propose to reference the tenth edition, reaffirmed in 2015, in these
sections and in Sec.  111.105-7(a) concerning approved equipment. The
tenth edition includes new requirements for equipment containing lasers
or lithium batteries, criteria for the use of adhesives in the
construction of electrical equipment, surface temperature limits,
attachment plug loading, and the maximum temperature of equipment in
contact with gypsum. Additionally, it incorporates a comprehensive list
of definitions for use in standards for electrical products and
outlines the relationship between this standard and electrical product
standards. We propose incorporating the more recent edition in subpart
111.105 to ensure that standards are consistent for electrical
installations on all vessel and facility types.
     Canadian National Standard (CAN)/CSA-C22.2 No. 157-92--
Intrinsically safe and nonincendive equipment for use in hazardous
locations, reaffirmed 2016. This standard specifies the testing of
nonincendive electrical equipment and the details of construction and
tests for intrinsically safe electrical equipment for use in hazardous
locations. We currently reference the 1992 edition of this standard in
Sec. Sec.  111.106-3(b) and 111.108-3(b). We propose to reference the
reaffirmed 1992 edition in those sections as well as Sec.  111.105-7(a)
concerning approved equipment. The two editions of the standard are not
substantively different and incorporating it into Sec.  111.105-7 would
provide an additional option for vessels and facilities.
     MIL-DTL-24640C with Supplement 1--Detail Specification
Cables, Lightweight, Low Smoke, Electric, for Shipboard Use, General
Specification for, Nov. 18, 2011. This specification covers
lightweight, low smoke, electric cables for Navy shipboard
applications. MIL-DTL-24640C is already incorporated by reference and

MIL-C-24640A (1996), currently referenced in Sec. Sec.  111.60-1 and
111.60-3. We propose to incorporate the updated edition, MIL-DTL-24640C
(2011), into Sec.  111.60-1 only, because this proposed rule would
delete Sec.  111.60-3. The updated edition, published in 2011,
incorporates the latest developments in marine cable materials and
performance enhancements but will not substantively change
requirements.
     MIL-DTL-24643C with Supplement 1A--Detail Specification
Cables, Electric, Low Smoke Halogen-Free, for Shipboard Use, General

C37.27-1987 which we currently reference in Sec.  111.54-1. IEEE
C37.27-2015 contains many technical updates to address advancements in
circuit breaker manufacturing technology, which would provide the
public with more accurate and applicable standards for modern circuit
breakers than the previous 1987 edition. We propose incorporating this
guide as one of several acceptable circuit breaker standards listed in
Sec.  111.54-1.
     IEEE 45-1998--IEEE Recommended Practice for Electric
Installations on Shipboard--1998. IEEE 45-2002 superseded the subject
1998 edition, but in some instances the Coast Guard previously found
the 1998 edition preferable and continued to reference it. Because the
1998 edition is no longer supported by IEEE and other acceptable
standards exist where it is referenced, we propose to delete all
references to this standard, which includes Sec. Sec.  111.30-19,
111.105-3, 111.105-31, and 111.105-41.
     IEEE 45-2002--IEEE Recommended Practice for Electrical

111.60-5, 111.60-11, 111.60-13, and 111.106-19 with IEEE 45.8-2016. The
technical content of IEEE 45.8-2016 is similar to IEEE 45-2002, but
more detailed.
     IEEE 1202-2006--IEEE Standard for Flame-Propagation
Testing of Wire and Cable with Corrigendum 1 (21 Nov. 2012), 2006. This
standard provides a protocol for exposing cable samples to a
theoretical 20 kilowatt (kW) [(70,000 British thermal units per hour
(Btu/hr)] flaming ignition source for a 20 minute test duration. The
test determines the flame propagation tendency of single conductor and
multi-conductor cables intended for use in cable trays. We currently
reference the 1991 edition in Sec. Sec.  111.60-6 and 111.107-1(c). We
propose to reference the more recent 2006 edition in Sec.  111.107-
1(c), but not in Sec.  111.60-6, because we are proposing to delete
that section on fiber optic cable. In the 2006 edition, the normative
references have been updated, the temperature at which cables are
conditioned has been raised from 18 [deg]C to 25 [deg]C, and minor
refinements to the test procedure have been made.
     IEEE 1580-2010--IEEE Recommended Practice for Marine Cable
for Use on Shipboard and Fixed or Floating Platforms, 2 Mar. 2011. This
recommended practice contains the requirements for single or

edition (1995) of this standard in Sec. Sec.  111.60-1, 111.60-3, and
111.60-5 while the third edition (2011) is referenced in Sec.  111.106-
5(a). We propose to reference the more recent edition 4.0 (2016) only
in Sec. Sec.  111.60-1(a) and 111.106-5(a), but not Sec.  111.60-3
because we propose to revise subpart 111.60 regarding cable
construction. The 2016 edition of this standard includes updates for
advancements in insulation and sheathing materials, construction
methods, and test methods. Its incorporation ensures consistent, up-to-
date standards for electrical cable installations.
     IEC 60092-354:2014--Electrical installations in ships--
Part 354: Single- and three-core power cables with extruded solid
insulation for rated voltages 6 kV (Um=7.2 kV) up to 30 kV (Um=36 kV),
Edition 3.0, 2014-08. This part of the IEC 60092 series of standards
provides manufacturing requirements and characteristics of such cables
directly or in directly bearing on safety and specifies test methods
for checking conformity with those requirements. We propose to
reference this standard in Sec.  111.60-1(a). This will align Coast
Guard requirements with those of recognized classification society
rules and industry practice.
     IEC 60092-360:2014--Electrical installations in ships--
Part 360: Insulating and sheathing materials for shipboard and offshore
units, power, control, instrumentation and telecommunication cables,
Edition 1.0, 2014-04. This part of the IEC 60092 series of standards
specifies the requirements for electrical, mechanical and particular
characteristics of insulating and sheathing materials intended for use
in shipboard and fixed and mobile offshore unit power, control,
instrumentation, and telecommunication cables. We propose to reference
this standard in Sec.  111.60-1(a). This will align Coast Guard
requirements with those of recognized classification society rules and
industry practice.

     IEC 60092-376:2017--Electrical installations in ships--
Part 376: Cables for control and instrumentation circuits 150/250 V
(300 V), Third Edition, 2017-05. This part of the IEC 60092 series of
standards provides manufacturing requirements and characteristics of
such cables directly or in directly bearing on safety and specifies
test methods for checking conformity with those requirements. We
propose to reference this standard in Sec.  111.60-1(a). This will
align Coast Guard requirements with those of recognized classification
society rules and industry practice.
     IEC 60092-401:1980--Electrical installations in ships--
Part 401: Installation and test of completed Installation, Third
Edition with Amendment 1 (1987-02) and Amendment 2 (1995-04). We
currently reference the 1980 edition in Sec. Sec.  111.05-9 and 111.81-
1(d). This proposed rule would make formatting changes to the
standard's title for consistency with the titles of all other
referenced IEC standards, but does not alter the edition incorporated
by reference.
     IEC 60092-502:1999--Electrical installations in ships--
Part 502: Tankers--Special features, Fifth Edition, 1999-02. This part
of the IEC 60092 series of standards deals with the electrical
installations in tankers carrying liquids which are flammable, either
inherently, or due to their reaction with other substances, or
flammable liquefied gases. The standard details the zonal concept for
hazardous area classification. We currently reference the 1992 edition
in Sec. Sec.  111.81-1, 111.105-31, 111.106-3(b), 111.106-5(c),
111.106-15(a), and 111.108-3(b). We propose to remove reference to this
standard in Sec.  111.105-31 and add it into Sec. Sec.  111.105-1,
111.105-3(b), 111.105-7(a), 111.105-11(b), 111.105-17(b), 111.105-
50(c). This proposed rule would make formatting changes to the
standard's title for consistency with the titles of all other
referenced IEC standards, but does not alter the edition incorporated
by reference. Additionally, we propose to allow classification of
hazardous locations based on this document. That proposal is described
in more detail in section VI.D later in this discussion of the proposed
rule.
     IEC 60092-503:2007--Electrical installations in ships--
Part 503: Special features--A.C. supply systems with voltages in the
range of above 1kV up to and including 15 kV, Second edition, 2007-06.
This part of the IEC 60092 series of standards covers the design and
installation requirements for AC supply systems with voltages in the
range of above 1 kV. We currently reference the first edition (1975) of
this standard in Sec.  111.30-5(a). We propose to reference the more
recent second edition (2007) of this standard. The second edition
covers a greater range of voltages and has updated technical
requirements.
     IEC 60331-11:2009--Tests for electric cables under fire
conditions--Circuit integrity--Part 11: Apparatus--Fire alone at a
flame temperature of at least 750 [deg]C, Edition 1.1, 2009-07. This
part of IEC 60331 specifies the test apparatus to be used for testing
cables required to maintain circuit integrity when subject to fire. We
currently reference the first edition (1999) of this standard in Sec.
113.30-25. We propose to reference the more recent 1.1 edition (2009)
of this standard, which includes minor technical updating, to ensure
the latest industry practices based on changes in technology are
addressed.
     IEC 60331-21:1999--Tests for electric cables under fire
conditions--Circuit integrity--Part 21: Procedures and requirements--
Cables of rated voltage up to and including 0.6/1.0 kV, First Edition,
1999-04. We currently reference this 1999 edition in Sec.  113.30-
25(j). This proposed rule would make formatting changes to the
standard's title for consistency with the titles of all other
referenced IEC standards, but does not alter the edition incorporated
by reference.
     IEC 60332-1-1:2015--Tests on electric and optical fibre
cables under fire conditions--Part 1-1: Test for vertical flame
propagation for a single insulated wire or cable--Apparatus, First
Edition with Amendment 1 (2015-07), 2004-07. This part of IEC 60332
specifies the apparatus for testing the resistance to vertical flame
propagation for a single vertical electrical insulated conductor or
cable, or optical cable, under fire conditions. This standard, along
with IEC 60332-1-2:2015, supersedes IEC 60332-1:1993 currently
referenced in Sec.  111.30-19(b). We propose to replace the superseded
1993 standard in 111.30-19(b) with IEC 60332-1-1:2015 and IEC 60332-1-
2:2015. IEC 60332-1-1:2015 covers the test apparatus and IEC 60332-1-
2:2015 covers the testing procedure. The technical content is similar
to the 1993 edition, but has been updated with greater specificity
regarding the ignition source, test sample size, and positioning of the
test flame.
     IEC 60332-1-2:2015--Tests on electric and optical fibre
cables under fire conditions--Part 1-2: Test for vertical flame
propagation for a single insulated wire or cable--Procedure for 1kW
pre-mixed flame, First Edition with Amendment 1, 2015-07. This part of
IEC 60332 specifies the procedure for testing the resistance to
vertical flame propagation for a single vertical electrical insulated
conductor or cable, or optical cable, under fire conditions. This
standard, along with IEC 60332-1-1:2015, supersedes IEC 60332-1:1993,
which we currently reference in Sec.  111.30-19(b). We propose to
reference IEC 60332-1-2:2015, regarding the testing procedure, in Sec.
111.30-19(b). The technical content is similar to the 1993 edition, but
the updates in the standard provide greater specificity regarding the
ignition source, test sample size, and positioning of the test flame.
     IEC 60332-3-21:2018--Tests on electric and optical fibre
cables under fire conditions--Part 3-21: Test for vertical flame spread
of vertically-mounted bunched wires or cables--Category A F/R, Edition
2.0, 2018-07. This part of IEC 60332-3 specifies the procedure for
testing the resistance to vertical flame propagation for vertically-
mounted bunched wires or cables, under defined conditions. Edition 2.0
(2018-7) retains and updates pre-existing categories of tests, adds a
new category (category D) for testing at very low non-metallic volumes,
and emphasizes that it applies to optical fibre cables as well as
metallic conductor cables. We propose this standard for incorporation
in Sec. Sec.  111.60-1(b) and 111.107-1(c).
     IEC 60332-3-22:2018--Tests on electric cables under fire
conditions--Part 3-22: Test for vertical flame spread of vertically-
mounted bunched wires or cables--Category A, Edition 2.0, 2018-07. This
part of IEC 60332-3 specifies methods of test for assessment of
vertical flame spread of vertically-mounted bunched wires or cables,
electrical or optical, under defined conditions. We propose to remove
references to the superseded first edition (2000) of this standard in
Sec. Sec.  111.60-1, 111.60-2, 111.60-6, and 111.107-1. Because Sec.
111.60-6 does not need to reference this test, we propose to delete
Sec.  111.60-2 and to reference the more recent edition 2.0 (2018) of
this standard only in Sec. Sec.  111.60-1 and 111.107-1(c). This more
recent edition retains and updates the pre-existing categories of
tests, adds a new category (category D) for testing at very low non-
metallic volumes, and emphasizes that it applies to optical fibre
cables as well as metallic conductor cables.
     IEC 60529:2013--Degrees of protection provided by
enclosures (IP Code), Edition 2.2, 2013-08. This standard describes a
system for classifying the degrees of protection provided by the
enclosures of electrical equipment as well as the requirements

for these degrees of protection and tests to verify the requirements.
We currently reference Edition 2.1 (2001) of this standard in
Sec. Sec.  110.15-1, 111.01-9, 113.10-7, 113.20-3, 113.25-11, 113.30-
25, 113.37-10, 113.40-10, and 113.50-5. In these sections, we propose
to reference the more recent edition 2.2 (2013) of this standard.
Edition 2.2 (2013) is a minor technical update to the standard.
     IEC 60533:2015--Electrical and electronic installations in
ships--Electromagnetic compatibility--Ships with a metallic hull,
Edition 3.0, 2015-08. This standard specifies minimum requirements for
emission, immunity, and performance criteria regarding electromagnetic
compatibility (EMC) of electrical and electronic equipment for ships
with metallic hull. We currently reference the second edition (1999) of
this standard in Sec.  113.05-7(a). We propose to reference the more
recent edition 3.0 (2015) of this standard. This edition includes the
following technical changes with respect to the previous edition:
    [cir] The scope and title have been modified to limit the
application of the standard to installations in ships with metallic
hulls only;
    [cir] The normative references have been updated;
    [cir] Further explanation for in-situ testing has been given in
section 5.1;
    [cir] Cable routing requirements in Annex B have been amended; and
    [cir] A new Annex C EMC test report has been added.
     IEC 60947-2:2019--Low-voltage switchgear and controlgear--
Part 2: Circuit-breakers, Edition 5.1, 2019-07. This standard provides
circuit-breaker construction and testing requirements. We currently
reference the third edition (2003) of this standard in Sec.  111.54-
1(b). We propose to reference the more recent edition 5.1 (2019) of
this standard. The 2019 edition of this standard contains numerous
technical updates addressing technical advancements, including circuit-
breaker testing, instantaneous trip circuit-breakers, and
electromagnetic compatibility.
     IEC 61363-1:1998--Electrical installations of ships and
mobile and fixed offshore units--Part 1: Procedures for calculating
short-circuit currents in three-phase a.c., first edition, 1998-02.
This proposed rule would make formatting changes to the standard's
title for consistency with the titles of all other referenced IEC
standards, but does not alter the edition currently incorporated by
reference. We currently reference this 1998 edition in Sec.  111.52-5.
This proposed rule would move the standard to the new Sec.  111.51-4(b)
because we propose combining the requirements of subparts 111.51 and
111.52 into a single subpart 111.51 (Calculation of Short-Circuit
Currents and Coordination of Overcurrent Protective Devices).
     IEC 61439-6: 2012--Low-voltage switchgear and controlgear
assemblies--Part 6: Busbar trunking systems (busways), Edition 1.0,
2012-05. This standard states busbar service conditions, construction
requirements, technical characteristics and verification requirements
for low voltage busbar trunking systems. We propose to add it to the
revised Sec.  111.59-1 concerning general requirements for busways.
     IEC 61660-1:1997--Short-circuit currents in d.c. auxiliary
installations in power plants and substations--Part 1: Calculation of
short-circuit currents, First Edition, 1997-06. This standard describes
a method for calculating short-circuit currents in DC auxiliary systems
in power plants and substations. We propose to include it in the
revised Sec.  111.51-4(b) as an alternative for short-circuit analysis.
     IEC 61892-7:2019--Mobile and fixed offshore units--
Electrical installations--Part 7: Hazardous areas, Edition 4.0, 2019-
04. This standard contains provisions for hazardous areas
classification and choice of electrical installation in hazardous areas
in mobile and fixed offshore units, including pipelines, pumping or
``pigging'' stations, compressor stations and exposed location single
buoy moorings, used in the offshore petroleum industry for drilling,
processing, and for storage purposes. We currently reference Edition
2.0 (2007) of this standard in Sec.  111.108-3(b). We propose to update
the reference in Sec.  111.108-3(b) to the more recent edition 4.0
(2019) and to insert new references to this standard in Sec. Sec.
111.105-1, 111.105-3(b), 111.105-7, and 111.105-17(b). The standard has
been completely rewritten. The Explosion Protection Level concept has
been introduced as an alternative risk-based classification method and
the requirements for installations in hazardous conditions reference
IEC 60079-14 and other relevant standards, as appropriate. The
incorporation of this standard into subpart 111.105 will provide an
alternate standard for classifications for hazardous locations.
     IEC 62271-100:2017--High-voltage switchgear and
controlgear--Part 100: Alternating-current circuit-breakers, Edition
2.2, 2017-06. This standard provides construction and testing
requirements for circuit-breakers having voltages above 1000 V. We
currently reference Edition 1.1 (2003) of this standard in Sec.
111.54-1(c). We propose to reference the more recent edition 2.2 (2017)
of this standard. There have been numerous technical updates to address
technical advancements in switchgear. To ensure we address the latest
technologies and industry practices, we are proposing to incorporate
the more recent edition of this standard.
     IEC-TR 60092-370:2009--Technical Report--Electrical
installations in ships--Part 370: Guidance on the selection of cables
for telecommunication and data transfer including radio-frequency
cables, Edition 1.0, 2009-07. This technical report gives guidance and
basic recommendations for the selection and installation of shipboard
and offshore unit cables intended for electrical systems used in both
essential and non-essential analogue or digital signal communication,
transmission, and control networks, including types suitable for high-
frequency signals (i.e., signals with a frequency of more than 10\5\
Hertz). We propose to reference this new standard in Sec.  111.60-1.
This will align our requirements with those of recognized
classification society rules and industry practice.
     IEC/IEEE 80005-1:2019--Utility connections in port--Part
1: High voltage shore connection (HVSC) systems--General requirements,
Edition 2.0, 2019-03. This standard describes the design, installation,
and testing of HVSC systems, on board the ship and on shore, to supply
the ship with electrical power from shore. Ships may be required by
state or local laws to connect to high voltage shore power (over 1000
V) rather than running their onboard generators. We propose in Sec.
111.83-7 that these ships meet the requirements of this standard.
     International Convention for the Safety of Life at Sea
(SOLAS), Consolidated Text of the International Convention for the
Safety of Life at Sea, 1974, and its Protocol of 1988: Article, Annexes
and Certificates. (Incorporating all amendments in effect from 1 July
2014), 2014. SOLAS provides requirements for vessel construction,
arrangement, and management on international voyages. We reference
SOLAS 2001 requirements in Sec. Sec.  111.99-5, 112.15-1, and 113.25-6
and propose to incorporate the latest 2014 edition of SOLAS. While the
applicable sections of SOLAS referenced in these requirements have not
changed, for completeness we are incorporating the latest SOLAS
amendments because industry is likely to use the more recent edition.
     International Maritime Organization Resolution
A.1023(26)--

Code for the Construction and Equipment of Mobile Offshore Drilling
Units, 2009. We propose nonsubstantive formatting change to the listing
of this resolution in Sec.  110-10-1(b). Chapter 6 of this resolution
is referenced in Sec.  111.108-3(b). The resolution provides
requirements for machinery and electrical installations in hazardous
areas of mobile offshore drilling units.
     International Society of Automation (ISA) RP 12.6--Wiring
Practices for Hazardous (Classified) Locations Instrumentation Part I:
Intrinsic Safety, 1995. We are proposing to delete this standard from
reference in Sec.  111.105-11. It has been withdrawn by ISA, is no
longer supported by ISA, and is not available at www.isa.org. Instead,
we propose to reference NFPA 70 and IEC 60092-502:1999 for the
intrinsically safe system requirements in Sec.  111.105-11.
     ISO 25861--Ships and marine technology--Navigation--
Daylight signaling lamps, first edition, Dec, 1, 2007. We are proposing
to reference this standard in Sec.  111.75-18 regarding daylight
signaling lamps. This standard provides performance requirements for
daylight signaling lamps pursuant to chapter V of SOLAS, 1974, as
amended, and chapter 8 of the International Code for Safety for High-
Speed Craft. The performance standards for daylight signaling lamps
currently in Sec.  111.75-18 are based on the international
requirements in place in 1996. These requirements have been superseded
by the requirements contained in ISO 25861.
     Lloyd's Register Type Approval System-Test Specification
Number 1, March 2019. This specification details performance and
environmental testing required for products used in marine
applications. We currently reference the 2002 edition of this standard
in Sec.  113.05-7(a). We propose to reference the more recent 2019
edition. It has been updated several times to keep pace with changes in
environmental testing.
     National Electrical Manufacturers Association (NEMA)
Standards Publication ICS 2-2000 (R2005)--Industrial Control and
Systems Controllers, Contactors, and Overload Relays, Rated 600 Volts,
2000. This edition is referenced in Sec.  111.70-3. NEMA reaffirmed the
edition without change in 2005. We propose to reference the reaffirmed
date in the standard's title, which would result in no substantive
changes.
     NEMA Standards Publication ICS 2.3-1995--Instructions for
the Handling, Installation, Operation, and Maintenance of Motor Control
Centers Rated not More Than 600 Volts, 1995 (R2008). This edition is
referenced in Sec.  111.70-3. NEMA reaffirmed the edition without
change in 2008. We propose to reference the reaffirmed date in the
standard's title, which would result in no substantive changes.
     NEMA Standards Publication No. ICS 2.4-2003 (R2102)--NEMA
and IEC Devices for Motor Service--a Guide for Understanding the
Differences, 2003. This edition is referenced in Sec.  111.70-3. NEMA
reaffirmed the edition without change in 2012. We propose to reference
the reaffirmed date in the standard's title, which would result in no
substantive changes.
     NEMA Standards Publication No. ANSI/NEMA 250-2018--
Enclosures for Electrical Equipment (1000 Volts Maximum), Edition 14,
2018. This standard covers classification of enclosures for electrical
equipment as well as the requirements for these enclosures and tests to
demonstrate conformance with the requirements. We currently reference
the 1997 edition of this standard in Sec. Sec.  110.15-1, 111.01-9,
113.10-7, 113.20-3, 113.25-11(a), 113.30-25(e), 113.37-10(b), 113.40-
10(b), and 113.50-5(g). We propose to reference the more recent 2014
edition in these sections. The 2014 edition added several new enclosure
types as well as several minor construction details.
     NEMA Standards Publication No. WC-3-1992--Rubber Insulated
Wire and Cable for the Transmission and Distribution of Electrical
Energy, Revision 1, Feb. 1994. This is one of many options listed as a
standard for allowable current-carrying capacity. We propose to delete
it from Sec.  111.60-13(c) because NEMA rescinded the standard.
     ANSI/NEMA WC-70 ICEA S-95-658--Power Cables Rated 2000 V
or Less for the Distribution of Electrical Energy, Feb. 23, 2009. This
standard applies to materials, constructions, and testing of 2000 V and
less thermoplastic, cross-linked polyethylene, and cross-linked rubber
insulated wires and cables which are used for the transmission and
distribution of electrical energy for normal conditions of installation
and service, either indoors, outdoors, aerial, underground, or
submarine. We currently reference the 1999 edition of this standard,
NEMA WC-70ICEA S-95-658, in Sec.  111.60. We propose to reference the
more recent 2009 edition with the updated naming convention. The 2009
standard contains updates based on advancements in technology including
new cable jacket types and updated testing methods.
     National Fire Protection Association (NFPA) 70--National
Electrical Code, 2017 Edition. This code is referenced in many sections
of subchapter J and is the basis for electrical regulations worldwide.
Currently, both the 2002 and 2014 editions of the code are incorporated
by reference in Sec. Sec.  111.05-33, 111.20-15, 111.50-3, 111.50-7(a),
111.50-9, 111.53-1(a), 111.54-1(a), 111.55-1(a), 111.59-1, 111.60-7,
111.60-13, 111.60-23, 111.81-1(d), 111.105-1, 111.105-3, 111.105-7(a),
111.105-11, 111.105-17(b), 111.106-3(b), 111.106-5(c), 111.107-1(b) and
111.108-3(b)(1) and (2). We propose to reference the 2017 edition in
all the aforementioned sections where the NFPA 70 code is referenced.
We also propose to include Sec.  110.15-1 in the list of sections
referencing NFPA 70 because NFPA 70 is currently used in the definition
of ``Special Division 1''. Substantive changes to the NFPA 70 articles
between the previous editions include the following:
    [cir] Article 240--This article on overcurrent protection raised
the threshold for high voltage overcurrent protection from 600 V to
1000 V. Additionally, it addresses arc energy reduction of fuses rated
at 1200A or higher.
    [cir] Article 250.119--Section 250.119 details the identification
requirements for equipment grounding conductors. The 2017 and 2002
editions are similar, but the 2017 edition contains greater specificity
for specific installations and prohibits other cables to be covered in
manner that could confuse them with equipment grounding conductors.
    [cir] Article 250.122--Section 250.122 details requirements for the
size of equipment grounding conductors. The content in the two editions
is similar, but the 2017 edition adds requirements for multi-conductor
cable, consideration of instantaneous-trip circuit breakers or motor
short-circuit protectors, and greater specificity for flexible cord and
fixture wire.
    [cir] Article 250--This article on grounding conductors has been
updated based on changes in technology and has added requirements for
conductors in raceways and multiconductor cable.
    [cir] Article 314--This article on outlet or junction boxes has
several minor updates based on changes in technology or industry
practices.
    [cir] Article 368--This article on busways was reformatted and the
threshold for high voltage busways was raised from 600 V to 1000 V.
Additionally it provides more detailed wiring requirements.
    [cir] Article 400--This article on flexible cords and cable
provides several additional types of flexible cords as well as
conductor sizes, but the allowable

ampacities for the existing types of flexible cords and cables have not
changed. Additionally, it requires that the maximum operating
temperature be added to the required markings.
    [cir] Article 404--It has been clarified that this article on
switches in <1000 V systems and several additional switch types have
been added.
    [cir] Article 430--This article on motors now raises the threshold
for motors requiring additional protective measures from 600 V to 1000
V. Part X has been added to provide greater detail on adjustable-speed
drive systems. Additionally a variety of minor technical updates made
as well as referencing the latest standards.
    [cir] Article 450--This article on transformers raised the
transformer threshold for high voltage transformers from 600 V to 1000
V. Additionally minor editorial changes were made. For example, in
several sections the word ``sufficient'' was replaced with ``not less
than'' to ensure the intent was clear.
    [cir] Article 504--Sections 504.10, 504.30, 504.50 and 504.60 on
intrinsically safe system design are proposed to be added in Sec.
111.105-11 because ISA RP 12.6 has been withdrawn by ISA. The
requirements are similar and NFPA is the authoritative standard for
electrical engineering design.
     NFPA 77--Recommended Practice on Static Electricity, 2019
Edition. This recommended practice applies to the identification,
assessment, and control of static electricity for purposes of
