Hello, my name is Kevin, I have a 1984 Beaver Regency 38. We bought this a little over a year ago and have put about 7,000 miles on it since then, we have been to many camp sites and have had no problems until this last week end we took a short trip close by our home to a state park. I plugged into a 30 amp post that had gfci breakers and immediately tripped the breaker, I turned all my breakers of in the rv and reset the breaker on the post, it stayed on. I turned my main breakers on in the rv and the post breaker still remained on, when I would turn on any of my ac, heater, refig, it would trip the gfci. I have checked all my receptacles for proper wiring, and have checked my breaker box to make sure I had a ground tie bar and a neutral tie bar and that there was no mixing, or that there was none tied together.
I have been told by some that older ac units or any kind of older appliance can cause a gfci breaker to trip, if this is true is there a work around for this, or is there something else that I should be looking for.
