Grounding

My dad and I got in a discussion about the grounding rod which is recommended in all cases by the generator manufacturer.  I told him that it just wasn’t feasible for a guy with a mobile attraction to drive a 4′ stake in the ground – a lot of times I will just be in the middle of a parking lot or tarmac!

250.34 Portable and Vehicle-Mounted Generators.
(A) Portable Generators. The frame of a portable generator shall not be required to be connected to a grounding electrode as defined in 250.52 for a system supplied by the generator under the following conditions:
(1) The generator supplies only equipment mounted on the generator, cord-and-plug-connected equipment through receptacles mounted on the generator, or both, and
(2) The non–current-carrying metal parts of equipment and the equipment grounding conductor terminals of the receptacles are bonded to the generator frame.
(B) Vehicle-Mounted Generators. The frame of a vehicle shall not be required to be connected to a grounding electrode as defined in 250.52 for a system supplied by a generator located on this vehicle under the following conditions:
(1) The frame of the generator is bonded to the vehicle frame, and
(2) The generator supplies only equipment located on the vehicle or cord-and-plug-connected equipment through receptacles mounted on the vehicle, or both equipment located on the vehicle and cord-and-plug-connected equipment through receptacles mounted on the vehicle or on the generator, and
(3) The non–current-carrying metal parts of equipment and the equipment grounding conductor terminals of the receptacles are bonded to the generator frame.

Ultimately, a guy on one of the forums that I like put it best.  It is a “floating ground” the same as the generator (alternator) battery and chassis ground in your car.  It is a closed system, every electron that leaves the alternator returns to the alternator… period.
