Hunter 410 New Orleans
My 1999 Hunter 410 has never had a genset. I am presentlly installing one. The Hunter Owners Manual for this boat shows the Genset hot wire connects to the electrical panel at the same post that the shore power hot line connects to. The neutral line of the genset does connect to the genset on/off switch post, while the neutral line from the shore power connects to the 30A AC switch post. The slide prevents both switches being on at the same time. From that it appears that the ground circuits control which circuit is active. My original thought was that the power or hot circuits would be the switching circuits. I would appreciate any comments. Regards, Bobweiser

That does sound odd. that would make the genset windings "hot" while you have shore power connected.
There should be a source selector switch somewhere to prevent both from being on at the same time. Some are automatic and in the genset proper so perhaps the hot is switched that way. Both hot and neutral should be switched BTW to prevent the genset neutral to ground connection from, well, connecting neutral to ground when shore power is active.

When I installed my genset in my 1997 h40.5 my ship-off-shore switch interrupted the hot, neutral, and ground of my genset and shore power.
