What size breaker does a well pump need?

Reach4 Well-Known Member
The manual for your pump probably recommends a breaker size. For a 1/2 HP submersible pump, a 15 amp 2 pole breaker would be normal. You can run 12 AWG, but unless the run is very long, 14 AWG is sufficient.

Likewise, how many amps does a water well pump use?

For example, if the pump wattage is 2,200 watts, and the voltage is 110 volts, the current is 2,200 /110 = 20 Amps. This is the value of the amps drawn by the well pump.

Additionally, does a well pump need its own circuit? Check the power to your well pump Water well pumps are powered by electricity. They are usually run on their own circuit, which you can check in your home's breaker box.

Correspondingly, how many amps does a 1/2 HP well pump use?

Taking the 1/2 hp, 230 V example, when delivering 1/2 hp to the pump it draws 5.0 amps. However, if that same motor operates at its service factor of 0.8 hp (1/2 x 1.6) it draws 6.0 amps. In most installations, motors operate near the Maximum Load.

How many amps is a 3/4 HP well pump?

Re: Amp draw on a 3/4HP pump Running amps will be 6 to 8 amps.
