Welcome to our forum.
I am buying a Hot Spring Prodigy Hot Tub that's running 220 (I know it can also use 110, but this one is on 220.) It's a 2007 model. I'm having an electrician come over and install the correct wiring, but I don't know what I need, can someone chime in? Is it 50 amp, 30 amp, or something else? What EXACTLY do I need to tell the electrician I need? By the way this Hot Tub has a normal 220 plug on it that will just plug up directly...Thanks.
Chas, what exactly is the sales pitch for that type of breaker? Something about freeze protection? That if the heater breaker trips then the pump will still work? How often does that kind of situation actually occur?
