Cold weather and electricity was going off and on very often for about 3-4 hours before I thought to turn off breaker to spa. Once outages quit happening is when I tried to turn it back on and the breaker started tripping.
Guess I will start unplugging different circuits tomorrow and find what is tripping breaker.
Most of the time it trips immediately. The last time I shut off main breaker and left off for 30 minutes to let any internal resets to reset if there are any. When I turn the 30 amp back on, it took about 5 secs to trip.
