The Motor Wire Size Calculator will calculate the proper wire size for a given motor HP and voltage. This applies to three-phase AC motors. This calculator will also give you motor amps and recommended breaker size, starter size, heater size and conduit size.
3 Phase Motor Wire Size Calculator Micro Wiring
Calculate Reset Voltage - Enter the voltage at the source of the circuit. Single-phase voltages are usually 115V or 120V, while three-phase voltages are typically 208V, 230V or 480V. Amperes - Enter the maximum current in amps that will flow through the circuit. For motors, it is recommended to multiply the nameplate FLA by 1.25 for wire sizing.

The calculator is designed to accept the total line voltage and current of the combined three cables. The equation for the area of a single wire is modified to: A = \frac {\sqrt 3 I \varrho L} {V} A = V 3I ฯฑL. The factor of \sqrt 3 3 is needed to convert between the system's phase current and line current.
