I have a motor home with a 12kW 120/240V 50A vehicle mounted generator. The ground and neutral are bonded together at the generator as well as a ground to the vehicle frame. There is also a 120/240V 50A "shore" input option. It is 4 wire and brings the ground and neutral from whatever source is providing the shore power. The transfer switch between these 2 sources are 2 3 pole breakers that switch the neutral. There is a slider bar that prevents them both from being energized at the same time.
My customer has a requirement to always drive a ground rod. By code with this motor home I do not have to drive one. My question is does it hurt to have the vehicle frame tied to the ground rod while running on generator power? It does however seem like a bad idea to have the bond to the ground rod while running on shore power? Any thoughts.
