A/C tripping the breaker
Tough question here... Our 3 year old Coleman Mach air conditioner started tripping the breaker this week. It started Saturday. Breaker tripped. Reset, started and tripped again. This went on a...

Well, THAT was interesting!
Got down last week (post delayed a little bit) and everything was working fine. Let it run for 2 days and at 0300, the breaker tripped. I just happened to be awake so I checked. It wasn't the A/C breaker like wifey said, it was the MAIN!
That morning, I did some checking and thinking. On electric, I had the Fridge, A/C, Elec. hot water heater and an ice maker outside connected to the trailer. Perhaps a bit too much for the 30a trailer power. I decided to shut off the electric hot water and use gas. We don't use hot water that much.
Then I went and checked all connections and screws; they were all tight and fine. I cleaned the cooling fan under the power; it was a bit dusty and probably wasn't function to max ability.
Then I replaced the breaker. This Main blew several times before when I had electric heat going and some other stuff. Figured it may be weak from all the times it had been tripped. Problem is that the main was also part of the A/C breaker so I had to get a special 30/20 breaker. Not a Home Depot or electric supply breaker....as I found out the hard way. Quick trip through traffic to the RV supply and got the new breaker for $20
Installed and everything has been working for about 5 days now.
I'm guessing that all the appliances kicked on at one time tripping the breaker which would possibly explain the time between trips.
Thanks all for the help and suggestions!! Much appreciated!!!
