A/C Breaker

[whaler23]

My 74 36C's A/C panel is located in the locker in the head, it looks and I'm assuming it's original. It appears I may have a breaker going bad on the salon unit (the breaker on the left side of the box) as it will consistently blow after about 6 hours of use. I have checked to make sure it isn't water flow, load, etc... the unit routinely cycles on and off throughout the 6 hour period. The front unit does not have this problem. It's a double breaker and my question is how should I determine what kind it is, where can I get a new one, and can I swap it with the front unit to make sure it's the breaker.

as long as they are the same, you can swap them or swap the wires if long enough.

you should be able to look at the size printed on the back or side.... I've replaced/added a couple on my 1970 panel. the only problem is that most of the breakers you will find don't use stud and nuts but screws which make it a little harder to connect. overall size should be the same.

it coudl be the breaker, but it could be something inside the unit, so swap the breaker first to eliminate that.
