Help me find a new 30 amp breaker

[buster53]

Ok, I have a 2001, model 356, with 2, 30 amp connections. Pretty sure one of the main 30 amp breakers on my electrical panel is going bad and needs replacing. It is listed in my parts manual as #8900333, 30 amp, 3 pole main breaker. I’m sure this breaker was used in many hundreds, if not thousands of Carvers built in that time period.
Doing an internet search of marine breakers, I can’t find this breaker, including a search of West Marine. Any suggestions of where I can look? FYI, I did open up the panel to eyeball this breaker, so I do know what it looks like…just can’t seem to find a replacement.
Thanks.

Heh Buster....did it have an id tag on it ?....if so you can check blue sea systems for a match. I got some from marina chandleries and amazon. Just double check the panel fit....screw spacing.

If this is the one it seems like they are very rare which is reflected in the price. https://www.ebay.com/itm/404771292766

If you really want to verify it before just swapping out parts, then swap circuit #1 and circuit #2 breakers and see if your problem moves to circuit #1 (or the problem on circuit #2 goes away). When you pull them out, there is likely numbers stamped on the side identifying exactly what make and model the originals are.

Actually, I thought about doing just that. I’ve got a marina guy coming to look at it this week along with another problem I’m having. Will chat with him about it.

Just a follow up…
My repair guy took a look at it, determined it is an obsolete breaker. Put a new one in and all is good. Confirming it was a bad breaker all along, which I was 95% certain.

Thanks for posting, many times it is just the simple obvious heh. Enjoy your switching...
