Most people are under the delusion that ground are for electrical safety. They are not.
No delusion there, a grounded system is safer in that it provides a known and low impedance path for fault current back to the source.
I think you are confusing Equipment Grounding Conductor (EGC) vs. Grounding Electrode Conductor (GEC).
The GEC or ground rods, building ground, etc. is used as a return path for high voltage events such as lightning.
The EGC bonds everything together and returns fault current back to the source. In this case the source would be the generator. For instance, if an extension cord rubs against the trailer chassis, rather than having the voltage sit there on the metal parts of the trailer, the current returns to the generator. If the fault is large enough, the low impedance path back to the gen should be high enough to trip the gen output breaker. |
Anyone knowledgeable about electric grounding on trailer mounted generator?
