If I'm understanding 702.10 correctly, 702.10(A) discusses separately derived systems where the neutal gets switched in the transfer switch and the neutral and ground on the portable generator are bonded. In a non-separately derived system, the neutral does not get switched and the neutral and ground on the generator are not bonded.
A customer picked up a portable generator with the neutral and ground bonded together from the factory. They plan to feed lights and the frig with extension cords only. They didn't want to main transfer switch installed at the panel (residential home), but ordered a 15A furnace transfer switch to have just the boiler hardwired. It has a male inlet for an extension cord feed. The TS only breaks the hot leg of it's 120V branch and not the neutral.
My confusion is since the neutral for the TS remains unswitched going back to the panel, then should the bonding jumper be removed on the generator? If yes, now we have a floating neutral for the lights and frig that will be fed with extension cords. We left the bonding jumper on the generator since the recepatcles are not GFCIs, but I don't want to create a potential shock hazard. My suggestion was to install a seperate ground rod for the generator, but the customer questioned it.
Is a ground rod needed? Any thoughts?
