10 Hp Electric Motor 3 Phase Amp Draw

The first step to convert hp to amps is convert hp to watts.

10 hp electric motor 3 phase amp draw.

Always use the f l a. The same power of motor would draw 3 5 amps at 480 v single phase but a 480 v supply could most likely be a three phase suppy and. Branch circuits that contain two or more motors must have wire in which the ampacity rating of the wire must be at least 125 of the full load current of the largest motor plus the sum of full load currents for the rest of the motors. Motors ac vfd drive 3 phase power training about 90 marketing may 17 2020.

Motors horsepower and amps of 230vac and 460vac 3 phase 60hz electric motors here are the full load amp fla values for typical 230vac and 480vac 3 phase motors. Always check nameplate information before designing protective devices wiring and switch gear. I ac3ø current ampere 3 phase. Multiply hp horsepower by 746.

Since 1 hp is equal to 746 w simply multiply the horsepower by 746 for this conversion. As a rules of thumb amps horsepower rating can be estimated to. I ac2ø current ampere 2 phase. This calculator will also give you motor amps and recommended breaker size starter size heater size and conduit size.

The are only intended to be guidelines and in all cases the full load amps of the motor nameplate should be used for final calculations. The tables below are intended to be a general guide for ac motor full load amperes. 3 phase ac motor f l a. Since motors are not 100 efficient the number of amps needed to achieve the power output is actually higher depending on the efficiency.
