Single phase voltages are usually 115v or 120v while three phase voltages are typically 208v 230v or 480v.
Ampacity rating copper wire conductors.
For motors it is recommended to multiply the nameplate fla by 1 25 for wire sizing.
Amperes enter the maximum current in amps that will flow through the circuit.
Voltage enter the voltage at the source of the circuit.
Specify cosf load power factor when load is specified in kw or hp.
Now you can take the advantage of this calculator to do this job j you can also check the classical wire cable size calculator in awg calculating wire cable size formula for single phase circuits.

Wire is sized by the american wire gauge awg system.
Wire gauge refers the physical size of the wire rated with a numerical designation that runs opposite to the diameter of the conductors in other words the smaller the wire gauge number the larger the wire diameter.
