Yes I always thought bonding neutral and ground outside of the first point of disconnect could create voltage in grounded appliances. Just trying to figure out if that was similar to the generator situation.No. I don't know what you mean by back feeding the ground. The grounding conductor (normally) doesn't carry any current unless there is a fault. The ground and neutral should only be bonded at one point (by code) and that is in the breaker panel. The why behind that is explained in a dizzying number of places and videos on the web and can be explained a lot better than I can here. Keep in mind we are not talking about a separately derived system where the neutral is switched as well as the hots, nor are we talking about a stand-alone generator feeding devices directly plugged in or on an extension cord.
