What is MCM in cable size?
circular mils
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 is the size in square millimeter mm2 is the cable of 250 mcm size?
Standard sizes
| Area | Diameter | |
|---|---|---|
| (kcmil, MCM) | (mm2) | (mm) |
| 250 | 126.7 | 12.70 |
| 300 | 152.0 | 13.91 |
| 350 | 177.3 | 15.03 |
How is mm2 cable measured?
Measure the diameter with calipers. Place an electrical wire between the jaws of a set of Vernier calipers. Slide the movable jaw around the cable without compressing the insulation and read the measurement where the line from the moving indicator meets the stationary scale for a diameter.

What is 300 MCM wire?
Our THHN 300 37 wire is part of our large catalog of hook-up and lead wire. This wire features a 300 AWG stranded bare copper conductor, PVC insulation, and a Nylon jacket. This bare copper building wire has a voltage rating of 600V and a maximum temperature of 90°C.
When to reduce the ampacity of a cable?
Where the number of current-carrying conductors in a raceway or cable exceeds 3, the allowable ampacities shall be reduced per the table below. For ambient temperatures other than 30°C (86°F), multiply the allowable ampacities shown above by the appropriate factor shown per the table below.
What does MCM stand for in wire chart?
MCM means 1000’s (M) of (C)ircular (M)ils
How is the ampacity of a wire measured?
Wire Ampacity – Metric compared with English Wire size is usually identified as the area of the conductor in square millimeters. The following sizes are for 60ºC insulation, copper wire, 3 current carrying conductors in a raceway. Sizes over 6 square millimeter are normally stranded so the measured diameter will be slightly larger.
What does MCM and kcmil stand for in AWG?
AWG Cross Reference Wire Sizing Chart. MCM means 1000’s (M) of (C)ircular (M)ils. kcmil means 1000’s (K) of (C)ircular (M)ils. Mil means 1/1000 inch.
