What is the difference between MCM and kcmil?
MCM is the old way of denoting the size, and kcmil is the newer way of stating the same thing. So, here is an example of how this works: Lets say you are pulling a run of 500 MCM or 500 KCMIL. That means you are pulling a conductor that has a cross section of 500,000 circular mils.
What is 500 mcm wire used for?
What is 500 mcm cable used for? Southwire THHN/MTW/AWM Wire is primarily used in conduit and cable trays for services, feeders, and branch circuits in commercial or industrial applications as specified in the National Electrical Code.
What does 50 MCM equal in AWG?
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. Circular Mil means the area of a circle 1/1000 inch in diameter. AWG = -4.3125 LN (mm2) + 17.16 (approx interpolated) AWG = -4.3125 LN (inch2) - 10.74 (approx interpolated)

What is bigger 4 0 or 250 MCM?
Circular Mils Kcmil sizes are used instead of AWG for sizes larger than 4/0 AWG. The smallest standard size is 250 kcmil, the largest 2000 kcmil. The sizes follow no obvious logic.
