How do I choose a motor wire size?
The cable size is equal to the 1.5 times of the full load current of the motor/load. Hence the cable rating formula can be written as, Cable size = 1.5 x Full Load Current.
What size wire do I need for a 30 hp motor?

How do you determine amperage wire size?
Wire Size & Amp Ratings To calculate the load requirement for a circuit, first add up the wattage of all the electrical devices that will be on the circuit. Then, divide the total wattage by the voltage of the system, typically 120 or 240, and that will give you the required current or amps.
