Cajun Circuit Breakers

[Birddog22]

Need help replacing circuit breakers, this is what I have. The company Mechanical products Inc. out Jackson Mich. said I need a part #, without it they can't help me. I can't find a part# anywhere. Does anyone know what the amps might be? Thanks,

Unfortunately, mine look exactly the same - plain white breakers, no indication of amperage on any, no part numbers.
I did find this wiring diagram:

Sorry couldn't be of more help.
If you search on The Hull Truth, there are some good discussions on determining wire size and fuse/circuit breaker sizes for various boat electronic devices. Bottom line, you don't want to over size the breaker, or you risk meltdown and fire before the breaker ever trips.
