shore/generator switch

scottgledhill · #1 (**permalink**) 12-04-2002

I am currently upgrading the wiring on a Norseman 447. It is equiped with a generator and has a switch to for shore, off, and generator settings. I can not locate a name on the switch. I am looking of a schematic for switches of the this type. Can you help?

Probably built by the folks who built your distribution panel. I have a similar set up and that was the case with mine.

cheers

Ship-Shore Power Transfer Switches come in a wide variety of confugurations. You can determine which terminals are open or closed to each other /w an ohmmeter.
The (usually blue body, black handle) Rotary style switches cannot be reliably switched under load, and are very failure prone. I''d replace this, if it''s what you have.
I''d suggest a pair (1 each: shore & generator) of Double Pole (if 120V) or Three Pole (if 120/240V) Breakers with a Lock-Out Slide Device, such as Blue Sea Systems #4130/4131.
