Breaker Tripping Problems


(Eric asks...)

I have a 31 ft. Fleetwood Prowler and when I plug the power cord in to any outlet it will trip the general purpose 15 amp breaker. I didn't have problems before winter storage. I don't have anything else on, either.


Coleen, the RVing editor comments:

I can't say for sure, but here are some possibilities on what might be causing your breaker tripping problem…

You may have bad batteries. They can go dead sitting over the winter and sometimes cannot be revived. If the plates have deteriorated, they may be causing an extraordinarily big draw on your converter.

Rodents. A mouse or some other rodent may have chewed on some of your wires. That could cause a short. They may also have made a nest in an electrical box, which in turn has drawn moisture and created a short.

Moisture may have gotten into your electrical boxes some other way. Instead of rodents, bugs could be the culprit for the nesting. Water may also have seeped into your electrical boxes through a crack in the caulking or other leak.

Your best bet may be to have a certified RV technician take a look at it.

Sometimes It's the Breaker
by: Dwight

Circuit breakers occasionally go bad in regular houses. So it only follows that is more likely to occur in an RV where the indoor climate is not as tightly regulated. Before tackling this, remove your unit from shore power first. Also, shut off the batteries if your unit has an inverter (a device that changes 12v DC to 110v AC). As an additional measure of safety, store the shore power cord out of sight lest some well meaning soul plugs it back in for you. Then remove the cover panel from the breaker box, remove the wires from the 15A breaker, and finally remove the breaker itself, usually by gently prying and lifting it out. Take it with you to a local hardware store first since it will usually be cheaper there than an RV parts store. Make sure you get an EXACT physical AND electrical replacement. If you managed to get this far, installing the new breaker should be easy.
