Replacing AC circuit breaker - Maxum Boat Owners Club

iceman · 07-17-2019, 05:40 PM

So the little plastic tab broke off of one of my AC circuit breakers. I would like to replace the breaker, so I tried to remove it today. I removed a clear plastic piece behind the labels, and the two wires. I don't see anything holding it in, but the breaker won't budge. I don't want to force it, or remove a bunch of other stuff unnecessarily. Does anyone know the secret of liberating one of these breakers?

Pics are attached showing the front panel, and a view from the rear with the broken breaker disconnected from the wiring.

2006 Maxum 2600SE. Thanks!

Something looks odd about that picture and I can't put my finger on it.

Is that factory wiring?

To the best of my knowledge, yes, it's original factory wiring. I'm not the original owner so it's possible he did something with it, but I doubt it.

So, an update: I got the breaker out. There is a plastic cover on the front of the breaker panel that hides two screws. After removing those the breaker was free, but I also had to partly disconnect the bus bar to get it out of the way.

Now I have the breaker in hand, and I've had no luck finding a replacement. It's a 5 Amp breaker made by Carlingswitch. See the attached pic, which shows the part number. Anyone know who sells these? Or if there are compatible alternatives? Thanks!

Thanks for the update on how to remove the breaker. Hopefully someone can point you to a source.

My bad. It's AC. Common positive and switched grounds. I was thinking DC, which is backwards. I was expecting all the wires to be yellow (or red), not black.

Simple failure to pay attention to details on my end.

No worries Shrew, yes it's the shore power panel, all AC circuits.

Thanks for the links folks. I called Carling, the breaker was a special order and is no longer made. They said it's possible some distributors have overstock, but they didn't know of any. Great Lakes Skipper has a Carling breaker that has very close specs and the same form factor. Has a white toggle instead of black but otherwise very similar. It's made for Carver yachts but it seems like it should work. I ordered it... keeping my fingers crossed.
