MCM (kcmil) Wire Size. MCM and kcmil are interchangeable terms measuring wire size in thousands of Circular Mils. A Circular Mil (cmil) is the area of a circle with a diameter of a mil. A mil is a unit of length equal to 1/1000 of an inch. MCM wire sizes have larger diameters than AWG wires.We also have to account for the 80% NEC rule (10.91A × 1.25 = 20.45A); this is the minimum ampacity of a wire we need. Choose the wire size based on the minimum ampacity. 12 AWG wire has 20A ampacity; it’s too small. 10 AWG wire has 25A ampacity (above the required minimum of 20.45A). That means that we need to use a 10 AWG …Table 3.10.1.19 Allowable Ampacities of Single-Insulated Conductors, Rated 0 Through 2 000 Volts, 150°C Through 250°C (302°F Through 482°F), in Free Air, Based on Ambient Air Temperature of 40°C (104°F) Size mm 2 (mm dia.)
