I completed the rewire ...yadda, yadda yadda (omitted for brevity)
My second protection device is a GFI. This is in line with my power cord. I did a test at my garage where I ran the space heater with the generator and grounded the hot lead to my house water pipe. The GFI did not trip. I also grounded the genset to the water pipe. I checked the voltage between the green wire and the hot lead and found about 60v as expected. When I grounded this 60v point the GFI didn't trip and the voltmeter on the genset didn't budge - 115v solid. Can anyone tell me what's going on here?
I have learned a lot from this thread. Thanks again for any help you can offer.
Scott,
Scottnjenrv:
Did you have the genset connected to an earth ground that would be common with the cold water pipe you used as a GFI test? I suspect the fault path the genset would see was incomplete.
If the genset is not grounded to an earth ground, then the GFI cannot see the ground return "fault" that it is designed to protect from.
Let me know if that helps the GFI work correctly to protect the user.

Ted,
Both the genset and my test set up were grounded to the water pipe. The genset was grounded at the external post where you normally connect the green wire to a rod driven into the ground. ???
