Tripping Breakers

We have a Sydney Outback 340 FBH. We a 50 AMP reducer plugged into a 20 AMP extension cord. It has worked fine since we plugged it in last Sunday, but yesterday it tripped the breaker after running the A/C. My husband has unplugged everything to check the connections. He reset the breaker and has even turned the Main off in the camper, but it is still tripping the breaker in the garage where it is plugged in. We have been staying in it because, subsequently, the air in our house is not working either and it is 85 degrees. Does anyone have anything else we can troubleshoot? It is hot, I am tired, and my husband refuses to go to a hotel. Thank you!

    You are saying the breaker "where it is plugged in", but is it actually the GFI that's tripped? If so, the GFI will not reset if the breaker in the basement for that outlet is also tripped. You must reset the basement breaker before the GFI will reset.

    I think the AC won't run on 20amp efficently you need 30amp. Rent a 3000 watt generator and put it in the garage.



    Surely you don't mean running that generator in a garage ????

    Sometimes, over time, a breaker will get more sensitive and trip. Replace it and see what happens.

    Hi,

    Are you saying the breaker for the garage trips when the main breaker in the RV is turned off?

    If so, unplug the RV from the cord. Does the garage breaker still trip? Then the problem is in the cord.

    If the breaker does not trip with just the cord, then check to see if the battery bank in the RV is fully charged. Set the fridge to propane, and the water heater to propane.

    Do you have a meter to monitor the voltage inside the RV? It would be best if it were no lower than about 108.

    Something in the house is running on the same circuit that the camper is plugged into. Once the AMP draw reaches the breaker capacity, the breaker pops. The breaker doesn't care if the electricity is going to the camper or to the refrigerator in your house. All that breaker knows, once it hit it's maximum load, it pops it's top. Check inside the house. You may find you have things plugged into the same circuit that's drawing electricity. Unplug everything on that circuit in the house, turn everything off on that circuit. That's why so many install a dedicated RV electric box for use with their campers at home, to make sure nothing else is drawing power through the same circuit.

    Bad connection or ground on the adapter, the extension cord or your main power cord
