Hi,
I have a hot tub that I hooked up about 2 months ago and has been working great. Now it has just started to snow here in Michigan and gotten colder. The breaker has started to trip after about 10 minutes of the jets being on. I will then reset the breaker, go turn the jets back on, and they will run for about 10 minutes and then the breaker will trip again. It does not trip when the jets are off (overnight) although one pump does turn on during the night for circulation. (The spa has 2 pumps). It is currently wired from the spa to a 50 amp GFCI box and then from the GFCI box to the main breaker panel where I have two- 30 amp breakers connected to it. It is only one of the 30 amp breakers that is tripping and is always the same one. (Never the GFCI breaker outside) Could you guys help me to try and decide the steps to take to find out the issue? The spa is a 220v dual pump spa with ozonator. It also did trip once about a month ago but has not happened since. It was warmer then as well. Not sure if temperature has anything to do with it. I also would like to add that I just changed the filter to a new filter approximately a week ago. The filter is the same size as the old one. The breaker first started tripping the first time I had the jets on after I installed the new filter. Maybe just a coincidence?
Thank you!
