How do you upgrade a circuit from 120V/20 Amp to 230V/30 or 50 Amp?
I want to add an outdoor spa to an existing pool, but the pool electrical only has 120V/20 Amp breakers. For the spa, I need 230V/30 or 50 Amp breakers added. Is this difficult/expensive to do? Do I need to rewire existing wiring? Do I need a dedicated circuit just for the spa, or can the existing wiring be upgraded so as to also be able to power the spa? Thanks in advance.
To upgrade it to 220V you need to bring another leg from the curcuit panel to the outlet. To upgrade the amps you need to upgrade the breaker & wire carrying the juice. If you have to ask this type of thing…. you’d better call an electrician. I know how to do it & I’d be very careful & check/recheck my calcs on wire size.
The penalty of doing it wrong (your house burning down, maybe w/ you or your children in it) v. the little bit to put in a single curcuit.
Call an electrician. It shouldn’t be too expensive.
