Not sure which wire your referring to. All references to neutral show as being there and there is a secific warning against removing the nuetral wire.

What I'm trying to do is use this gen. for my house.There is neutral bonding at the service panel therefore I need to make my gen. floating
Bonded.This will eliminate the neutral being bonded twice.I'm not using
A transfer switch.

I'm wondering if the jumper on the terminal block between ground and the and neutral if removed will solve the issue.

Remove the connection at P1-5

What people do, it make a twist lock plug with N and G shorted for those times you want to operate the generator stand-alone. Generally you don't need the 240 when doing this.

Hello,

I also have the same problem on my Generac GP8000E. I contacted Generac and they told me they could not tell me how to remove the bond to create a floating neutral when connecting to a 2 pole transfer switch. It would violate their UL rating to do so.

Then I asked if they would send me a picture of the wiring and point out the bond jumper on it and they said no.

I understand the code states to have the neutral bonded to the ground at one point only but what will happen if I use the generator as is connected to a transfer switch using a 4 prong 240 V plug? I guess the 120 V GFI outlets on the generator would see current on the ground and trip but would the 30 Amp breaker for the 240 V plug trip? I don't think it is also a GFI.

Thanks,

Rich
