Breaker Tripping at the Pole - Culprit Found
We have a 2015 29QBS and a few camping trips back we came across an issue whereby after about 30 minutes of being hooked up to shore power (30 amp) the breaker on the pole would trip. The plug itself was incredibly hot but not the breaker which indicated to me this was the trailer and not the pole. Further verifying this is it happened during two subsequent camping trips. I began trimming down the appliances we were using until it stopped tripping. Unfortunately, I could not run anything on electric at the same time as the A/C and in Florida that can be problematic.
Luckily, the solution was an easy one. Our dealer found that a wire on the back side of one of the breakers was about a half a turn loose. This causes the camper to draw way more amperage than needed, popping the breaker at the pole and not in the camper.
So, if you are tripping at the pole, and your plug is hot, check to see if a screw on a breaker has backed out a bit from road vibration.
