[QUOTE="Phil Graham, post: 129226, member: 430"] Re: How much generator? Ben, A path to ground via Generator ->GEC -> Grounding conductor is [B]not[/B] a safety component for portable generator systems. Indeed the NEC in article 250 specifically [I]excludes[/I] this as a compliant ground fault return path. The bonding between the neutral and the EGC at the genset provides the fault current return path to trigger the OCPD. Bonding of the GEC/GC pair to the EGC, Neutral, and genset frame at the generator [I]does not[/I] provide the fault current return path. The grounding conductor serves to hold the bond point at a potential that matches the local earth potential. [/QUOTE]
