How To Size Cable -

Sizing cables for motors? Remember that the current depends on the power factor. A motor running at half load will have a lower power factor, drawing more current than you might expect for the output power.

[ I_b = \fracPV \cdot \cos\phi ] Three-phase AC: [ I_b = \fracP\sqrt3 \cdot V \cdot \cos\phi ] Where: (P) = load power (W), (V) = line voltage, (\cos\phi) = power factor. how to size cable
