Glossary Term: kcmilMCM is an abbreviation for thousands of circular mils, an old measurement of wire gauge. 1 MCM = 1 kcmil = 0.5067 square milimeters. A mil is 1/1000 inch. A wire 200 mils in diameter is 40 MCM. MCM is generally used for very large-diameterwire.

What is 350 MCM wire? 350 MCM THHN CU wiring is made from annealed copper wire. It has anAWG of 350, which means its cross-section features 350,000 circular mils. The wire also has a diameter complete cable (O.D.) of 777 mils, a phase conductor insulation thickness of 60 mls, and a jacket thickness of 8 mils.

Is MCM and Kcmil the same thing? One circular mil is equal to the area of a circle with a diameter of one mil (one thousandth of an inch). The circular mil is intended for reference to the area of a wire with a circular cross section. MCM is the old way of denoting the size, and kcmil is the newer way of stating the same thing.

What is the cross sectional area of a 500 Kcmil? 0.7073 sq in
