AC blowing breaker in coach
SO it was 97 yesterday when I got home. The Coachmen is sitting in the cul-de-sac between trips and was 104 inside (DW closed all the windows vents etc., as it was thundering at 5:30 am but never rained).
Then found out the neighbor's A/C was out. Wanted to offer the camper to them, but I was uncertain if the A/C would run off the house. I have it plugged into a 20 amp run in the garage, but with 100ft of regular outdoor extension cord (not the heavy 30 amp cord) I sincerely doubted I was going to get enough juice out to the camper to urn the A/C. Went ahead and turned it on anyway.
It ran for about 10 minutes, and then blew the breaker inside the camper. Not the house...
This confused me. I would assume the 20 amp breaker in the camper would allow the A/C to pull 20 amps through it. Since I had at max 20- amps hitting the camper, and probably less, I assumed the weakest link was the breaker in the house.
The more I thought about it, the more I thought maybe the breaker in the camper is the problem. We have only ru the A/C a couple times, just have not been in hot weather, yet. I tried it again after letting it sit for a while and did the same thing. By that time the camper had cooled off a little from all the windows open and dinky little fan in the bathroom running.
Any thoughts as to why the A/C breaker in the camper blew but not the supply breaker?
