Fuse Question

[BambiBirder]

My 20 amp fuse popped and I've tried to replace it twice. Each time it blows out right away. Anyone know what I can do about that?

Do you know what devices are on that particular circuit? If so, disconnect them and see if the fuse holds. If so, reconnect them one at a time. You could also use an ohm meter and look for the shorted device.

if the circuit not noted as to what it covers on the panel you will have to disconnect Every Thing powered by 120 volts in the trailer. The convertor, the frig, the microwave, the TV, the hot water heater if it has an electric element, and anything else that is so powered.

Once all are disconnected attempt to turn on the breaker. If it still blows it could be a failed breaker, replace and try again. If it still blows there is a shorted wire somewhere in the trailer, not that likely, or something 120 volts is still connected, more likely. If it holds reconnect, one at a time all those items you disconnected. If the breaker blows it problem is with the last item you plugged in.

The OP stated it is a problem with a fuse. I guess we need to know if it is a fuse or a circuit breaker. But he did say he replaced it twice and it blew. So I will assume it is on the 12 volt side of life and not the 120 volt.

That's correct I'm going to have it checked at an RV place now. Thanks for the help.
