The formula you are looking for is Amps = kW x 1000/1.73 x E x pf.
Use .84 for a power factor value.

How many amps will a 3 hp motor pull on 230 volts?
It depends on the voltage of the motor, and whether it is single-phase or 3-phase. A 120 VAC 2HP single phase motor draws almost 20 amps, a 240 VAC single-phase 2HP motor draws about 10 amps. A 480 VAC 2HP three-phase motor only draws about 6 amps.
How many watts is 1 hp at 480volts?
A 1-HP motor is reckoned to draw 7 amps at 240 v 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 the current in that case would be reckoned as 2 amps.
How many amps on 3 phase 225 amp panelboard each phase?
It means 225 amps on each phase.
How many Amps for 3 horsepower at 208 volts?
For a single phase 3 HP motor at 208 volts the amperage is 18.7 amps. For a three phase 3 HP motor at 208 volts the amperage is 10.5 amps. This figure is derived at by taking the full load amps at 230 volts and adding 10%. As the voltage goes down the amperage goes up. For 200 volt motors 15% is added to the FLA of a 230 volt motor.
How many amps required to run 10 ton air conditioner?
Your question is incomplete, but given the information presented if your motor was 100 percent efficient the current drawn by each phase would be 8.97 amps. No motor is 100 percent efficient so this number will not be the real world representation of your motor. answer= (746 w * 10hp) / (480 volts * Root 3) = 8.97 amps
Why is my single phase induction motor drawing to many amps?
I have a single phase induction motor. It draws 8 amps on start up and climbs to 14-15 amps when I put a load on it. When I don't have a load it runs at 1 and climbs to 2-3 amps. It is normal operation for this motor to run at the lower number of amps with a load. But I don't know what is wrong.
How many amps will a 3 hp motor pull on 230 volts?
It depends on the voltage of the motor, and whether it is single-phase or 3-phase. A 120 VAC 2HP single phase motor draws almost 20 amps, a 240 VAC single-phase 2HP motor draws about 10 amps. A 480 VAC 2HP three-phase motor only draws about 6 amps.
How many amps does a 3 phase 22kw motor use?
22 kw motor how much takes ampares with load
How many amps does a 50 horse power electric motor use?
Need to know the voltage of the motor.
How many amps does a 5 hp 208 volt 3 phase motor draw?
read the name plate on the motor
How many watts is 1 hp at 480volts?
A 1-HP motor is reckoned to draw 7 amps at 240 v 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 the current in that case would be reckoned as 2 amps.
How many amps does a 1 hp electric motor pull under a load?
T430.247 of the NEC shows that a 1 hp motor operating at full load on 115v will draw 16 amps, called Full Load Current (FLC). Conductors supplying this motor are required to be 125% of FLC which is 20 amps. Motor circuits are complicated things and do not follow the rules of other circuits. This motor, while drawing a maximum of 16 amps at full load and supplied with #12 AWG copper conductors can be protected by a breaker of 40 amps.
How many amps on 3 phase 225 amp panelboard each phase?
It means 225 amps on each phase.
How many amp does a three phase 430 volts 1 hp motor draws?
About 3 amps, maybe slightly less.
How many amperes for 3 phase 220v 5 tonner?
50 Amps Single Phase 20 Amps Three Phase
How many Amps for 3 horsepower at 208 volts?
For a single phase 3 HP motor at 208 volts the amperage is 18.7 amps. For a three phase 3 HP motor at 208 volts the amperage is 10.5 amps. This figure is derived at by taking the full load amps at 230 volts and adding 10%. As the voltage goes down the amperage goes up. For 200 volt motors 15% is added to the FLA of a 230 volt motor.
How many amps does a 2 hp 210 volt single phase motor draw?
Then you are trying to get more HP out of the motor that it can supply. Back off on the load that the motor is driving or put a bigger motor onto the load.
