The tables below are intended to be a general guide for ac motor full load amperes.

10 hp electric motor 3 phase amp draw.

460 volts motor 3 phase. As a rules of thumb amps horsepower rating can be estimated to. 230 volts motor 3 phase. This calculator will also give you motor amps and recommended breaker size starter size heater size and conduit size.

A 1 hp motor is reckoned to draw 7 amps at 240 v single phase. 1 1 2 3 5 7 10 15 20 25 30 40 50 60 75 100 125 150. I ac3ø current ampere 3 phase. Always check nameplate information before designing protective devices wiring and switch gear.

V dc voltage direct current. For example if there are three 15 amp motors in the circuit the ampacity rating of the wire feeding the. Enter the motor horsepower and voltage. Determine the current flowing through a three phase 2 hp 400 volt motor having an efficiency rating of 93 and a power factor of 0 9.

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. 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. 230 volts motor single phase. 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.

Multiply hp horsepower by 746. 3 phase ac motor f l a. Example if you have 100 hp multiply by 746. Written on the motor nameplate first if it is available.

Three phase amps hp 746 e age efficiency pf 1 73 example. Since 1 hp is equal to 746 w simply multiply the horsepower by 746 for this conversion. How to convert hp to amp ac 3 phases in only 3 step. Since motors are not 100 efficient the number of amps needed to achieve the power output is actually higher depending on the efficiency.

I ac2ø current ampere 2 phase. 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. The first step to convert hp to amps is convert hp to watts. Always use the f l a.

V l l voltage line to line. V l n voltage line to neutral.
