How many amps does a well pump use?

A 1 HP submersible well pump will require a 2.5 KW internally regulated generator to operate the pump. A 30 amp breaker means the pump is smaller than 2 hp will use ~13 amps/2300 watts during operation and will require a 4 KW internally regulated generator to operate the pump.

Why does my well pump keep tripping the breaker?

One common cause of a submersible pump tripping its breaker can be cracks or leaks in the housing. If your pump’s housing is cracked, water could be getting into the pump through these cracks and causing it to short circuit.
