As a rules of thumb amps horsepower rating can be estimated to. Written on the motor nameplate first if it is available. If service factor is 1.15, increase above amp values by 15%. View wire size charts from the list below. Always check nameplate information before designing protective devices, wiring and switch gear.
Web for more details into sizing wire and circuit protection devices for motors, view the motor wire size and circuit protection chart and the motor wire size calculator. The lower the fla, the more efficient the equipment is. Fla is usually determined in laboratory tests. Web three phase motor full load amps table. (1) when motor service factor is greater than 1, increase full load amps proportionally.
The voltages listed are rated motor voltages. Most motors are rated using peak hp consumed which is much higher than true continuous hp. (table by acme electric corporation). Written on the motor nameplate first if it is available. Always check nameplate information before designing protective devices, wiring and switch gear.
