I installed a Gentran swith in a house the other day and I checked out the generator (Generac 4000w), when I checked it I found the voltage from the hot leg to ground was 0 zip nada.... I tried to call Generac, and got a local sales rep who knew jack about it. I had a similar problem with a Honda generator (hot to ground was 65volts) and when I called them they said that was normal for that model.
Ok, so when these generator's are being used as a back up power source in a dwelling doesn't it become a seperatly derived system? And shouldn't the neutral be bonded to the ground in the generator?
I would appreciate anybodys input. Thanks in advance.
