I’m using a DuroMax12000EH Generator as a power back-up to my house for when the grid goes down. I’m feeding power from the generator directly into my house breaker panel (with an approved interlock device) from the generator’s 50amp 240volt receptacle. The two hot leads go directly into a bipole 50amp breaker on the panel, and the neutral and ground wires go (unswitched) directly into the respective neutral and ground busses in the panel. Because it is my house’s primary panel, the neutral and ground busses are connected together.
Because there is a grounding circuit established between the generator and ground at the panel with this particular set-up, it is redundant, and problematic, to ground the generator itself to a grounding rod as well. Further, it would be prudent to eliminate the possibility of grounding the generator through the frame via a circuit made by a human body!
Based on my review (captured in the picture below and verified by continuity testing between neutrals and grounds in each of the receptacles) my generator’s neutral and ground circuits are bonded to the frame.
Given this, I believe it would be prudent to convert the generator from a bonded neutral to a floating neutral configuration by disconnecting the short jumper wire that grounds the neutral (white wire) coming out of the windings to the generator casing. Check out the attached photo to confirm I’m doing the right thing.
I’m trying to be as safe/careful as possible!
Thanks for your guidance.
