I doubt it is anything but 30 amps. Make sure it is a double pole breaker that breaks both hot and neutral wires.

A proper shore power panel for 30 amp service has a double pole breaker (30 amp) as a main breaker with other breakers for each circuit, usually 15 amps, each wired with 14 gauge wire. The wire from the shore connection to the panel is 10 gauge wire. The panel includes reverse polarity indicator lights. This is a good example of a proper panel.



Many older boats came with just a single double breaker of 30 amps and that should be corrected so any individual circuit cannot draw more than the current it is rated for, typically 15 amps. I would think any good surveyor would consider this a requirement.

Ok I think I was about to screw up. I was getting ready to order the 30 amp. This breaker only controls the 115 shore power outlets. Maybe I should wait till my next trip down and pull it and then order.

For an individual circuit you want a 15 amp breaker. Blue Seas model # 7210 or similar.

You have two circuit breakers but no 30amp main ????
Is the polarity indicator wired across both circuits ?

I'm assuming the double pole main is above the reverse polarity light. There certainly has to be one.

I'd hope so but in my experience I wouldn't bet on it

Funny but scary.

The op's picture looks like a factory panel to me. He should have taken a pic of the entire panel.

Probably 15 amp. You will likely have a 30amp main breaker which feeds a 30 amp dual on your panel, that feeds 15 amp outlet breakers from there.

The 30 amp main double pole main breaker will feed the 15 amp circuits directly if done properly.

Agree with a GCFI on the first outlet in line on each circuit - it will protect any outlets downstream on the same circuit.

About 80% of the boats I see have significant electrical issues caused by inexperienced hands. I'd guess about 15% are potentially lethal and I don't understand why more people don't die.

Just for fun I threw up a little photo album of the stuff I see on a daily basis. I think it will be easy to see why I am a little cynical on the topic.

I agree - I too have seen issues such as live AC wires a few inches from bilge water covered with electrical tape and other disasters waiting to happen. I've wondered why more boats don't catch fire or injure as well.
