I am having problems with power to outlets. ive had several that had power than for no apparent reason they did not. and not in the same area. example, outlet in the salon, and one in the forward stateroom. and also in the engine room. I was discussing the problem with a friend and he seemed to think there are master circuit breakers somewhere close to where the shore power comes in, possible behind the AC circuit breaker panel. Does anyone know where these might be? I checked all the breakers on both the AC and DC panels and none where tripped. Any suggestions would be appreciated. Thanks

Your AC outlets are likely protected by a GFI outlet upstream. Look for a reset/test button on the face of a GFI outlet somewhere.

Another possibility is that there is a faulty connection in the ac panel. Have a qualified marine electrician check it out.

Hi,
If I am reading your post correct, you have some AC outlets that work and some that don't ? If so then I'd have a look how they are wired from the main AC panel, and is there one or multiple breakers for the outlets, if individually wired from the panel then there maybe connection faults in that area, but if they or some are wired in a radial system then there maybe connection faults behind the outlets.
Hope that helps

It would be helpful if you stated year and model of boat. My 3870 has GFI outlets in both bathrooms. If they trip I will lose power to both receptacles in salon ( as Builderdude stated correctly)
I would look at every receptacle on the boat and verify which have GFI's and then trip the GFI and check which receptacles lose power.

i would start at the post or outlet your boat power plugs into on the shore.

That outlet wired correctly, move on to your cord it ok etc you get the idea make sure power is getting to the boat sounds to me you have 220v one side is not getting power

Possible misconception and most definitely hard to follow.

First..... the OP does not mention whether or not the boat is equipped with 110 vac S/P or 220 vac S/P.
..... if the boat is in the US, and is equipped with 110 vac S/P, then he'll have one 110vac leg, one Neutral leg and an Earth Ground coming into the boat via his S/P connection.
..... if the boat is in the US, and is equipped with 220 vac S/P, then he'll have two 110vac legs, one Neutral and an Earth Ground coming into the boat via his S/P connection.

If 110 vac S/P....... a 110 vac outlet requires one 110 vac leg connection and one Neutral plus the earth ground.

If 220 vac S/P...... a 110 vac outlet require one of the two 110 vac legs, one Neutral and the earth ground. If one of the two 110 vac legs is not making continuity, that side of the panel will be in-active, in which case he will NOT have 220 vac available, but will have some live 110 vac circuits.

In other words..... we need more info from the OP!
