But George... if you are supplying the circuits soley from the generator... it IS a seperately derived service by definition and would need a service rated bonding jumper.

Gfretwell, if you REMOVE the bonding jumper in the generator it is no longer safe to use as a seperate unit for just the 120v receptacles at another time!? Right? Should I make up a jumper to fix that and instruct some ignorant homeowner to use this thing everytime you want to use your generator for the receptacles only... That's NOT safe either!!

Finally, I have yet to find online, and havn't checked at wholesale house yet, a Trasnfer switch made for switching the neutral. In these units are the individual circuit neutrals brought to a isolated bar in the transfer switch and then a pole of the switch transfers which neutral feeds it? (all while keeping it isolated from the transfer switch can since it has to go back to gen for bonding)
