I found my mom's submersible pump wired to a two single pole 20amp breakers and there is a double pole 30amp breaker on the bus panel as well. I already know that all 220volt leads need to be on a double pole breaker in case one leg grounds out. So I switch the wires over to the double pole 30amp breaker and tested the voltage with a volt meter and it has the 110 volts on each leg. However the pump will not run on the 30amp double pole breaker,and the pump has been running OK on the two single pole breakers! Should I have a 40amp double pole breaker installed?
