I need help here guys. Here is scenario. Customer rents Warehouse space with offices. Customer did not want to connect to Utility with a transfer switch because he does not own the place. So he wanted a portable generator set up that powered some Troffer lights and outlets to network equipement and computers without running extension cords every where when power was out. So basically it is a stand alone system that is only powered when fired up with Generator.
Connection = Generator 50 amp outlet to cord that enters a outlet that feeds a Subpanel with 50 amp breaker inside. Neutral and ground Not bonded. Ground to steel and not using ground from generator.
Problem = Full GFCI protected Power from Generator keeps tripping the GFCI when a flourescent light breaker is turned on whether the Generator ground is bypassed and connected to steel or if I send the ground back to the Generator itself. Trips right away.
Lights work fine with no ground to steel or no ground to Generator. ( I set up 2 of these systems in 2 of warehouses next to each other) ( both have same flourescent lighting issue. 2 different brand new Generators with same result)
Generac xp10000e that has a bonded neutral. I needed this generator for the true power to use on the Network equipement.
No sign of a actual ground fault and tried a light right next to Generator with same tripping result. Outlet powers a shopvac fine. No tripping.
I can understand the tripping if I was using the ground back to the generator. But how does it trip when I wire nut off the ground back to generator and do ground to steel?????
Any help would be deeply appreciated.
Thank You
