Type-2 DC Circuit Breaker Question

Yahoo Message Number: 62866
Greetings campers,

The 20 amp DC type-2 circuit breaker on the domestic fuse panel that monitors the overhead lights in the bathroom(s) and the bath vent fan has begun to "chatter" with a full load (i.e. all lights and the fan on for 10 minutes or more). It doesn't totally open, as some (reduced) voltage will continue to power the fan (barely). The circuit breaker is scalding hot to the touch when it does this. After cool down, it resets itself and life is good, until full load is applied again.

Do these things fail? If so, where can I find a replacement?

Has anyone experienced similar circuit breaker behavior?

Thanks,
Jay

Yes, they do fail. Replace it as fast as you can get one. Do not put it off. What yours is doing is how they fail. Can we say FIRE HAZARD. All that heat is going into your wires. Overtime, that causes over problems.

If the new one does the same thing, then you have bigger problems.

Jay, they do fail. I had a devil of a time trouble shooting a low voltage on a dydronic system on a SOB some years ago. I finally probed the voltage on each side of the circuit breaker and found my problem. Replacement of the circuit breaker solved the problem.

Good luck.

I had a problem with a type-2 circuit breaker back in the days when there was Country Coach tech support. One thing that Brian, the genius of all things electronic, told me was, even though they reset, each time they do so there is a small weakening of the device. Which means they trip later and reset later. I concur with the recommendation of Leonard Kerns- replace the CB ASAP.
You should be able to find them at a good automotive supply store or automotive electrical shop in your area. If not, ask everyone you talk to where they might suggest you look. That technique has gotten me a lot of answers when, for some reason, they don't volunteer the information.
An on line source might be http://www.wiringproducts.com/contents/en-us/d28.html. If that doesn't do it, Google "type- 2 circuit breaker, 12 volt". And buy several!
