"In electrical wire sized 350mcm, what does the ""mcm"" stand for" In electrical wire sized 350mcm, what does the mcm stand for. kgb answers » Local & Lookup » Definitions & Word Origins » In electrical wire sized 350mcm, what does the mcm stand for. MCM stands for Thousand Circular Mils. For very big wire sizes (fatter than 4/0), the wire gauge system is usually abandoned for cross-sectional area measurement in thousands of circular mils (MCM), borrowing the old Roman numeral M to denote a multiple of thousand in front of CM for circular mils..

Ohmmeter An ohmmeter is an electrical instrument that measures electrical resistance, the opposition to an electric current. Micro-ohmmeters (microhmmeter or microohmmeter) make low resistance measurements. Megohmmeters (also a trademarked device Megger) measure large values of resistance. The unit of measurement for resistance is ohms (ω). The last ohmmeters were based on a type of meter movement known as a 'ratiometer'.

What does 500 mcm AWG mean? 500 mcm wire is a stranded wire with the equivalent of 500,000 circular mils in cross-sectional area. A c … ircular mil is a circle with a diameter of 1 mil, or 1/1000th of an inch. 500 kcmil means the same thing.t is a wire size, the equivalent cross sectional area in thousands of circular mils. e.g. 500 MCM or kcmil = 500,000 circular mils. The circular mil is a unit of area used especially when denoting the cross-sectional size of a wire. It is the equivalent area of a circle whose diameter is 0.001 (10-3) inch.
