I just bought the $49 home depot spa box for my new build. All the wiring, connectors, etc. I bought are rated for 30A (which should be fine for my single 5500W element). In addition to the 50A gfci that came with the box, I want to use a standard 30A breaker to protect the circuits from over current. Can I put the 30A breaker in the main box and still use the 50A gfci in the spa box or should it be the other way around?
