My electrician changed the 60A indoor circuit breaker on my breaker panel because the pin holding the two poles of the breaker broke. He replaced it with a 50A breaker that had a sturdy clasp over the two poles. After he did that I tried running the hot tub with the dip switch #10 setting to the high amp (50A) setting. My hot tub is now working exactly as it should! Does that make sense?
