Re: backup generator neutral ?
Ed. Are you saying you can not get electrocuted at this connection? I would agree that the possibility is very low. I understand that unbalanced load is trying to get back to the source. But it can choose the easist path and the grounding system at the pole to the generator may be that path. You would still have the concern of lighting or other voltages hitting the utility neutral as in a primary line falling on it. I stick to my guns that it is safier to use a 3 blade disconnect for single phase and a 4 blade for a 3 phase system.
