The formula you are looking for is I = kW x 1000/1.73 x E x pf. I = 1.5 x 1000 = 1500. 1500/1.73 x 400 x .86 = 1500/595 = 2.5 amps.
A standard motor's efficiency between 5 to 100 HP is .84 to .91.
A standard motor's power factor between 10 to 100 HP is .86 to .92.
A feeder for a motor has to be rated at 125% of the motors full load amps 2.5 x 125% = 3.1 amps
A #14 copper conductor with an insulation rating of 90 degrees C is rated at 15 amps.
No, a 4160 volt motor with a high inertia load will use a resistor bank in the starting of the motor.
5000 volt
Yes a 208 voltage motor will operate on 220 volts. You have to increase the motor overload protection by 10% of the motor's full load amperage to protect the motor.
Yes, but the motor's horsepower rating will not be reached.
It would probably be 20-30 amps. <<>> The electrical code book states a value of 18.7amps for a 3HP 208 volt motor. If the nameplate data is available it is always best to use it when calculating wire size and overload protection for the motor.

5000 volt
317.025280 KILOWATTS = 317,025.28 WATTS
Yes a 208 voltage motor will operate on 220 volts. You have to increase the motor overload protection by 10% of the motor's full load amperage to protect the motor.
20 HP Three phase 360 volt what is the amps
You can use an insulation rating 5000 volt to run 4160 volt supply.
Yes, but the motor's horsepower rating will not be reached.
It would probably be 20-30 amps. <<>> The electrical code book states a value of 18.7amps for a 3HP 208 volt motor. If the nameplate data is available it is always best to use it when calculating wire size and overload protection for the motor.
You can not change it. 440 volt is by design. However you run it with 220 single phase supply, but it would run far lower power.
Use a transformer.
If the motor wire numbers are L1, L2 and L3, it is not a single phase motor. It is a three phase motor. Also for future reference, a 220 volt single phase motor does not use a neutral.
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.
