How much current does a 1 hp motor draw?

What is the full load current of a 1 hp motor?

Full Load Current: Three Phase AC Motors

Motor Horsepower Motor Ampere
1 230V 460 V 4.2 2.1
1-1/2 230V 460V 6.0 3.0
2 230V 460V 6.8 3.4

How many amps does a 1 hp pump draw?

A 240 volt, 1 horsepower well pump draws 10 amps of current. When the pump starts, it can draw up to 35 amps, but only for 5–10 seconds.

What is the power of 1 hp motor?

If the motor is fully loaded, it will provide output power of 1 HP = (1 X 0.746) kW = 0.746kW. Electrical Input Power = (Output Power/Efficiency). Assuming 90% efficiency, Input Power = 0.746/0.9 = 0.83kW.

How much current does a 1 hp submersible pump draw?

A 1 HP submersible pump engine will draw a 3.2-amper current if it is a single-phase motor at 230 volts of voltage. If it is a three-phase motor at 440 volts, it will draw a maximum 1.7-amper current.

How much power does a 1 HP well pump use?

Different Sizes of Well Pumps and Wattages

Size of Pump Motor Running Wattage Starting Wattage
1 HP 2,000 to 2,400 4,000 to 7,200
1.5 HP 2,500 to 2,800 5,000 to 8,400

3 HP 5,000 to 5,500 10,000 to 16,500

What size breaker do I need for a 1 HP well pump?

So, the horsepower of the pump is the factor. For example, ½ HP pump needs a 15 amp breaker. But the ideal circuit breaker will be 25 amps for a 1 HP pump.

How do I calculate amps?

Calculating Amperage

A simple formula for calculating amps is to take the watts and divide that by the volts. So, for instance, if the wattage of the lighting fixture you’re working with is 60 and the volts are 12, divide 60 by 12 and you will get five, which are the amps.
