main breaker

The main breaker on our Oceanis 36cc will not turn on the land landshore electricity.

Any ideas what can be wrong ?

Re: main breaker

What happens? Does it click off immediately or stays on but no juice? If it clicks off you might have a short somewhere, maybe in battery charger or elsewhere. Maybe the breaker went bad.

If no juice check with ac voltage meter that you are getting juice at end of plug where it goes in to boat, behind breaker (one probe on screw behind breaker and other on negative bus bar). Track down where you have juice and where it stops.

When I had my 36CC, this was usually caused by the shore power being miswired...or missing gnd/neutral. You might start by using another drop/pedastal or digging out the DVM and checking the voltage at the plug.

Re: main breaker

I would respectfully suggest that dealing with the main breaker of your shore-power circuit is not a good place to start learning about trouble shooting marine electrical circuits. Incorrect testing/repair/installation procedures can lead to really undesirable consequences.... as in damage, fire, death.

Not an alarmist by nature (running with scissors is ok if you point them away from you), but you might want to get hold of a good marine electrician for this one. Then get a good book on marine electrical systems (Google Nigel Calder or John C Payne) and follow along learning how to understand and troubleshoot your vessels AC and DC systems in future situations.

If your electrician doesn't charge extra (Labor 35.00/Hr, 50.00/Hr if you watch, 70.00 if you help) ask some questions and pay attention while he solves this issue for you.

Re: main breaker

Our Jeanneau has a separate ELCI (similar to a GFCI) breaker in an aft locker near the power inlet. The delivering dealer relocated it from the nav station electrical panel to meet North American rules requiring the breaker to be within 10 cable feet of the inlet. Maybe you have a second inlet breaker that's tripped.

The problem has been solved.

The culprit was corrosion on the CEE (male) and NEMA (shemale) connectors on the landshore cable.

Cable and connectors are produced by Marinco and cofigured for 220V/50Hz.

Thank you very much to all for tips and advice

Replaced both connectors.
