Default Generac XC8000 E dead out of the box

I purchased a Generac XC8000 for a replacement for an older generator supplying primary power to my camp. Model is G0068260 Serial Number 3003887515. When I hooked the unit up to my power panel cable I could not get AC at the 220V socket. I could get 120V at the appropriate socket but when the plug is put into the 220V socket the GHCI circuit breaker trips and disconnects power. Every time right out of the box. Unit now has 9 hours on it as I used it with an extension cord from the 120V plug. I purchased the unit on line from Home Depot who have a no return policy on generators. I have not yet contacted Generac customer service. Would anyone have an idea as to what would cause this to always trip the GFCI breaker. Cable and inside wiring have been checked and work fine with a borrowed generator. Thanks guys.

My guesses are that (A) your borrowed generator does not have a GFCI on its "220V socket", and (B) the camp you are trying to feed has one or more neutral to ground bonds that are causing the GFCI to trip.

There is a very good chance that the generator is working as it is designed to. Generac will probably advise you to correct your camp's wiring.

I took the unit into the dealer for check out. Apparently the XC8000 comes from the factory with a bonded neutral. Here in New Brunswick the electrical code calls for a floating neutral. Hence the GFCI tripped when plugging into a floating neutral system. Easy solution seems to be remove the frame to neutral bond in the generator and adhere to local codes. Now to get back to the camp to test the theory.

Anytime the generator is used as a portable, the neutral should be bonded. It's not a difference in code it's a difference in intended use. The newest codes can cause these conflicts now due to some people use this generator as a portable (like camping or construction) and some will connect it to a pre-existing electrical system.

My son in law had the same issue with a brand new 10,000 watt Honda generator. I think when the dealers sell you a unit, they should be telling you this. It was just a matter of removing one wire in the unit and taping it up, but that's not the point. Some people lack the confidence to be messing around with the wiring on their brand new generator.
