What is the meaning of kcmil?
thousands of circular mils
Glossary Term: kcmil
MCM 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.
What size is kcmil?
0.5067 mm²
kcmil—In the North American electrical industry, conductors larger than 4/0 AWG are generally identified by the area in thousands of circular mils (kcmil), where 1 kcmil = 0.5067 mm². A circular mil is the area of a wire one mil in diameter.

What is KCM of a conductor?
KCMil – A method of measuring conductor size that stands for thousand circular mils. K represents kilo for 1,000. C represents circular, and mil, M, is 1/1000 of an inch. A wire that is one mil in diameter has an area of one circular mil or 1 KCMil. KCMil replaced MCM for sizing conductors.

Is AWG same as gauge?
Both Gauge and AWG are ideally the same. When writing, we call it a gauge for clear understanding. AWG measurements do not consider the insulation of the conductor. The higher the AWG number, the smaller the conductor.
How do I calculate wire size?
How do I calculate wire size for motors?
- Multiply the resistivity (Ω•m) of the conductor material by the peak motor current (A), the number 1.25, and the total length of the cable (m).
- Divide the result by the voltage drop from the power source to the motor.
- Multiply by 1,000,000 to get the result in mm2.
