I just ordered a new Pentair Superflo 1hp uprated, 2 speed, for 230 volts. Thanks to all the great people on this forum. I'm replacing a vintage and rusty 3/4hp superpump that died on me last week. I've got a temporary replacement working till my new pump arrives.
I need help with the wiring.
Here's the current situation:
Main breaker box: I have two single 20 amp circuit breakers linked together, typical of 220v, like my dryer breaker. so i'm guessing that 220v is being sent out of main breaker. I will test it later to be sure.
At pump location: i have a sub-panel that has two seperate breakers running at 115v: both single 20amp gfci breakers; breaker #1- booster pump, which is no longer being used; breaker #2-pool pump(old 115v superpump). When i took off the subpanel cover, power off at main box, of course; i see the main power line in: red wire going to breaker 1 and black wire goes to breaker 2. Green to grounds.
Can i change out the two single breakers in the sub panel for a 220v breaker?
Is SJOOW wire, 12 awg the correct gauge for the task?
Does the breaker need to be GFCI protected?
Does it need to be sheathed with a waterproof conduit? the pump is in enclosed garage, so no elements get to it
I am not opposed to hiring an electrician. I have done a lot of 115v wiring around the house, so i thought i might be able to tackle it. But 230v is a lot of voltage and i'd like to be on safe side.
