I hooked up my pop up to my 5500 watt generator to the 220 hook up, turned on the AC full cold, about thirty minutes later the 20amp breaker popped. Switched it back, had it running on low ac, popped in about five minutes, did this 2 more times with the same result. Breaker seemed loose at times but after moving it up and down a couple times would return to its correct positive to allow power again. We go camping for the first time July 5th to Fort Wilderness, so I really need to make sure AC is working consistently. Any suggestions would be received with great thankfulness!!!!
