100 amps
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.
Assuming the power factor is 1, a 10 hp motor operating at 600 volts in a three-phase system would draw approximately 13.33 amps.
To answer this question the pump's voltage is needed.
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.
A 10 hp pump operating at 480 volts would draw approximately 15.6 amps of current. This can be calculated by dividing the power in watts by the voltage.

106 amps
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.
To answer this question the voltage of the motor must be stated.
A single phase 10 HP motor will draw aproximately 50 amps. A three phase 10 HP motor will draw aproximately 28 amps.
It depends on the voltage-- I think at 110v it's 4 amps per hp
Assuming the power factor is 1, a 10 hp motor operating at 600 volts in a three-phase system would draw approximately 13.33 amps.
For a single-phase induction motor, allow 7 amps on a 240 v for a 1-HP motor. Therefore the formula is: current = 7 X HP x 240 / voltage
AWG #10 copper on a 30 amp breaker.
For a 1.5 hp 230v 3 phase motor, you can calculate the amperage using the formula: Amps = (HP x 746) / (Volts x Efficiency x Power Factor x √3). Assuming an efficiency of 0.85 and a power factor of 0.8, the amperage draw would be approximately 4.3 Amps.
HP = (Current x Voltage)/746, or HP = (IE)/746 (disregarding %Efficiency) So, you have to solve for I, current: I = (746 x HP)/E
current = power/ voltage current = 3700/ 240 = 15.4 amps
