Grounding a portable generator for house use
I have a generac XP8000E that I want to connect to my house. I plan to connect its 30A output to the main panel via backfeed through a 30A breaker. An interlock switch will be used for safety.
The manufacturer says that, if I unbond the neutral and ground within the unit, this will void the warranty.
Are there any other grounding strategies I could use? For example, what if I carry the ground from the panel only as far as the house inlet receptacle box, and then provide a separate earth-ground for the generator?
