power , P=1.732*V*I*power factor
so, the formula for calculate the load current for a 3 phase motor is,
I=P/(1.732*V*power factor)

What amp would a 440 3 phase motor have?
Need to know the horsepower of the motor.
What should the amp reading be Amp on 11kw motor - no load?
hi.. this is pankaj working as power engineer. we have a 11 kw induction motor which is used in fluidising blower. its no load current i sarround 9.5 to 10.6 amp. and under load its ampere does nt exceed 15 amp. its winding resistance is 1.4 ohm.
How can you find motor FLA without the motor nameplate The motor is single phase 120 vac?
use clamp on amp meter
How do you take an amp reading on three phase motor without an amp clamp?
This can be extremely dangerous if you do not know what you're doing. If you are even the slightest bit unsure call an electrician to do it. To measure amperage you will first have to turn the circuits off that feed the motor. Next you will have to open one of the connections for one of the phases and wire your amp meter in series with the motor meaning you will have to make the current pass through your amp meter and go into the motor once it is running. Make sure that your meter is sized and fused appropriately or you risk injury and damage to your meter, maybe even death.
Will a 12 dc volt 8 amp power supply run a 12DC volt 9 amp motor?
Yes but only up to a load torque of 8/9 of the rated torque.
Is a double throw 15amp breaker the same as a 30 amp breaker amp?
You have a double pole breaker for 240Volt supply. The maximum current is 15 amp.
What size breaker is used for a 3 horse power motor with 3 phase 208 volts?
I would go with 20 amp 3 pole 15 amp will also do
What is the difference between a 40 amp and 22 amp motor?
The 40 amp motor probably produces double the horsepower of the 22 amp motor.
In a commercial building What is the maximum amp load you can install in a 200 amp load center?
200 amp maximum combined.
What is breaker size for 240 volt 9 KW?
The formula you are looking for is I = W/E.
What is the maximum amps each phase conductor carries on 200 amp residential service?
If the mains is a 200 amp two pole breaker each leg can carry up to 200 amps in relationship to the common neutral of the service.
Is a 2 pole 30 amp circuit breaker equivalent to 30 amp?
Yes.
Can a 6 amp switch control a 12 amp motor?
No. A 6 amp switch is rated at 6 amps. A 12 amp motor will melt the contacts in the switch mechanism.
Can 10-2 wire be used for an outlet?
Yes you can. The existing 30 amp breaker on the two conductor #10 wire will have to be changed out to a two pole 20 amp breaker. The reason for this change out is that the new 20 amp outlet is only rated at 20 amps maximum. If the 30 amp breaker were left feeding the 20 amp device, It would be unsafe as it is 10 amps higher that the manufacturer's specifications of maximum amperage handling capacity of a 20 amp device.If the 30 amp circuit is only 120 volts, the neutral will have to be lifted from the neutral bar of that circuit and that will be the second wire that will be connected to the new two pole 20 amp breaker. This action will give you 240 volts across the new 20 amp outlet.
What amp light switch used in common household?
That would be a single pole 15 amp switch
Can I put a 40amp 2pole breaker on a 1 horse power well pump I am using?
No, the breaker size is too big. A 1 HP, 230 volt motor draws 8 amps. The electrical code recommends for a motor with a full load amps of 8 amp that it use either 25 amp non time delay fuse, 15 amp time delay fuse or a 20 amp two pole breaker. These sizes will work up to 11 amp full load amps.
Will a 2 pole 60 amp ITE Gould or Westinghouse breaker replace a 2 pole 60 amp T and B unit?
If the breaker will snap on the bus bar, yes.
