Reconnected to shore power last night at our slip and now no power when the AC main breaker is on. Verified 120 from shore is there with meter and the Lewmar is not tripped. Any ideas?
 
I will ask all the "Of course I did" ones first.
When you checked to verify power from shore did you test at the end connection you plug into boat?
You moved selector to shore power?
On mine I have two AC main switches. On on the panel and one all by itself a bit lower.
And last but not least - are you sure you have a good connection at both ends of the plug?
 
Yes to all. Using multimeter we have 120 at dock tower, and at boat end of cord. All right. Mine is 2015 R27 and have only one AC main on top right of panel.
 
I would look for a breaker labeled ELCI. that is the other one I mentioned that is all by itself. I believe it operates like a GFCI. Power goes from shore plug to boat connection to ELCI (looks similar to your other breakers) then to panel. If it is tripped you will not get power to panel. On some models it is next to panel. Some under AFT cockpit seat. Maybe someone with your year and model knows the answer. Seems it is either that or a bad main breaker. I would bet on tripped ELCI.
 
Another hint - regulations state ELCI must be installed within 10 ft of where shore power enters boat. I believe that confirms you have one and you only have to crawl around within 10 ft to find it. Here is a link discussing ELCI.

Thanks. I found another “main” breaker in the locker where battery switches are located. You’re absolutely right about electrical documentation, bit skimpy at best. All good
