Technical Glossary   120V AC The line to neutral voltage in a
single phase three wire AC system as commonly found in the US.
240V AC The line-to-line voltage in a single-phase three wire
(not including green safety ground) AC system as commonly found
in the US. 250V AC The line-to-line voltage in a single-phase
two wire (not including green safety ground) AC system as
commonly found in Europe and many other parts of the world. 3
phase see also Single Phase Refers to 3 phase power generation
typically 480V AC and higher. The AC utility is a 3-phase
system. In its simplest form there are three conductors
connected to three conductive coils, which pass through a
magnetic field, thus, inducing the electrons in the wires to
flow. As the polarity of the magnetic field changes from North
to South, electrons are induced to flow first one way then the
other. This produces AC current flow. The current that is
induced in the three wires is 120° out of phase. The current
flow in the first conductor starts 120° before the
