In the NEC, there appears to be two tables that contradict each other in regard to the minimum sized equipment grounding conductor.
In Table 250.66, it lists a 4 AWG copper grounding conductor for 2/0 copper or 4/0 aluminum service conductors, which are the sizes used for 200A services. However, in Table 250.122, it lists a 6 AWG copper grounding conductor for 200A service.
Could someone clarify this, or explain the differences?
