WebThe following AWG “American Wire Gauge” table shows the AWG Size and diameter in millimeter “mm” and inches in “in”, its cross sectional area in mm2, Inche2 and kcmil or MCM and resistance in ohms per 1000 feet and 1000 meter. The AWG size chart also shows the current in amperes for chassis wiring and power transfer application. AWG ... WebNov 28, 2024 · The wire size for a 12 V DC depends mainly on the current and the wire length. Follow these steps to calculate it: Determine the electric current I (i.e., 20 A), cable length L (i.e., 5 m), conductor resistivity ϱV (typically 3% of the source voltage). Input the values in the formula: A = (2IϱL) / V = (2 ⋅ 20 ⋅ 2.22 × 10⁻⁸ ⋅ 50 ...
