I go with Grampa Jim. Not knowing how many times that pad braker tripped, it should have been replaced. People don't realize that each time it trips, it gets a little weaker, till you could plug a light in and trip it.
If your at Disney now and nothing has tripped since you have been there tells me the Electrical Service at the Campground was wacky. Love Fort Wilderness go there 2-3 times a year. Matter of fact heading there next week for the Halloween party.

The electrician measured 26 to 27 amps while the breaker was still not tripped. That is very, very close to 30 and I would agree that a "weak" 30 amp pedestal breaker might trip in that range after 10 of 15 minutes of running. In addition, all it would take at that load is for your converter to cycle to a higher output(maybe turn on one more 12V device), or your water heater to cycle and down you go. Energy management is probably the key and I would guess that nothing is wrong as your next campground experience confirms. Lots of 30 amp breakers will trip after half an hour at 27!
