What size breaker should i use for a pool pump?

Question

the outlet the pool pump will be plugged into outside is coming into my house with a 12gauge wire, I want to connect the wire to my panel, is it ok to use a 30 amp breaker?

Answer 1

Best not to use a 30 amp breaker, as the cable is probably only good for a 20 amp load. Your pump can draw as much as 9 amps on start up, or under max load, depending on size. Ideally I would put a 16 amp breaker on the circuit (enough capacity for a salt chlorinator, pool light, party lights, etc.) If you really wanted to do it right, a separate earth leakage breaker is handy to stop all your power going off when the pumps decides to trip

Answer 2

Use the lowest breaker you can. Never more than the max amps for the cable?

Whats the power of the pump?

--------------------------------------...

Whats the max amps the pump will take

1.5 hp x 750 watts = 1125 watts

1125/ 240volt = 5 amp ?

pump may take higher amps on start up

Answer 3

you should check maxinum amp load of motor and size for that....the purpose of a breaker is to save the wire from burning out

Answer 4

NO use a 20 amp breaker.
