WebThe actual area of a Circular Mil is: A =Pi x r². A = 3.14159 x (.0005)² inches. A = .0000007857 square inches. When wires get very large their sizes are sometimes shown as "MCM", such as 250MCM. MCM means … Standard sizes are from 250 to 400 in increments of 50 kcmil, 400 to 1000 in increments of 100 kcmil, and from 1000 to 2000 in increments of 250 kcmil. The diameter in the table below is that of a solid rod with the given conductor area in circular mils. Stranded wire is around 5% larger in diameter to allow for gaps between the strands, depending on the number and size of strands.
