Keep in mind it is possible to trip the TT or 30 amp campground breaker. I had this happen once. The ac, tv and microwave were on and I turned on the hot water. When the electric element in the water heater kicked on the breaker in the TT tripped. I am glad I had read a post here about this or I would spent considerable time troubleshooting a nonexisting problem.
