NeilDR Posted September 18, 2009 Report Share Posted September 18, 2009 I just installed a new hot tub. I have two 100 amp panels. The hot tub 50 amp breaker is in a panel for lights and outlets. The tub will run for about 20 minutes and then the main breaker overheats and shuts off. I have shut off all breakers except the hot tub breaker and the 100 amp breaker still gets hot. The 50 amp breaker and the 50 amp GFCI never trip or get hot. Could the 100 amp breaker be weak? I am open to any suggestions. Thanks.

canadianrepairman Posted September 19, 2009 Report Share Posted September 19, 2009 check your wiring for a loose connection. If that doesn't work call an electrician Quote Link to comment Share on other sites More sharing options...
d1dennis2009 Posted September 19, 2009 Report Share Posted September 19, 2009 I would have to agree, you will need an electrician for this issue. Quote Link to comment Share on other sites More sharing options...
bart6453 Posted September 19, 2009 Report Share Posted September 19, 2009 I would have to agree, you will need an electrician for this issue. Need an electrician for sure....but it could be a voltage drop from your feed line. It sounds strange, but a voltage drop with the same amperage draw will cause an increase in temperature, possibly causing a trip in your breaker. Just an idea, most likely just a weak breaker or something simple. Quote Link to comment Share on other sites More sharing options...
stryker709 Posted October 4, 2009 Report Share Posted October 4, 2009 If you are turning off every other breaker in the panel and the 100 amp breaker still heats up and trips then I would say it's a bad breaker. I would probably make sure the 100 amp breaker was seated properly and ensure the lugs were tight on the wire first before changing it though. If it's a sub panel as you suggest, make sure you turn of the breaker that feeds this panel first. If it's the main panel, call an electrician.

Thanks for the suggestions, after checking the load limit on the panel, everything was fine. However, it seems that the main wire going to the panel from the service was loose. The tub is running fine. Thanks again. Quote Link to comment Share on other sites More sharing options...
