I think the reason is that an 8' rod in the soil will do no better than the equivalent of a #6 wire so they gave us a break. lol. Dangerous DIYer.But let's first look at what constitutes an equipment grounding conductor (EGC) and how it differs from the oft-misunderstood grounding electrode conductor (GEC) that connects noncurrent-carrying metal parts of the electrical service to the electrode buried in the earth. EGCs VS. GECs. Equipment Grounding Conductor (EGC): Table 250.122 Above the 800 amp breaker, the ratings hold a Amp 400 panel meter installed Meter amp 200 base 400 service replacing electrical subpanel Meter base amp 200 wiring diagram installation disconnect 200a … The ampacity of 4/0 aluminum per 310.16 is ...
