To answer this question the pump's voltage is needed.
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.
100 amps
A 1 horsepower (hp) 240-volt single-phase submersible pump typically draws around 4 to 5 amps under normal operating conditions. The exact current draw can vary based on the pump's efficiency and design. To determine the precise amperage, you can use the formula: Amps = Watts/Volts, where 1 hp is approximately 746 watts. Therefore, the current draw is roughly 3.1 to 3.5 amps (746 watts / 240 volts), but factoring in inefficiencies and starting current could increase this value.
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.
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.
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.
It depends on the voltage-- I think at 110v it's 4 amps per hp
24.87amps 1 hp=746 watts P=IxV ... (746x8)/240
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
1 HP = 745.70 wattsPower (watts) = Current (amps) x VoltsSo if you use a 110 volt system, amps = 745.7/110 = 6.779 ampsIf you use a 220 volt system, amps = 745.7/220 = 3.389 ampsFor a 12 volt system, amps = 745.7/12 = 62.142 amps
Look at the motor nameplate and it shoud have the amp draw on it. If the nameplate is missing, then the amp draw depends on what type of motor it is. The basic calculation to get you in the ball park would be as follows: 1 HP = 0.75 KW 7.5 HP = 5.63 KW Assume the efficiency of the motor is 80%, then the power supplied will need to be 5.63/0.8 = 7.04 KW amp draw = 7040/220 = 32 amps <<>> For calculation purposes the electrical code book states that a 7.5 HP motor draws 40 amps.
