However, if the ungrounded conductors are increased due to voltage drop, you lose the curve that is built into NEC Table 250.122 for reducing the size of EGCs due to 250.122(B). Section 250.122(B) ...

The equipment grounding conductor’s (EGC’s) purpose is to provide an effective ground-fault current path ... NEC Table 250.122 provides the minimum size for equipment grounding conductors based on the ...

Lightning protection system ground. Both the NEC (NFPA 70) and the National Lightning Protection Code (NFPA 780) require a separate, ... Most electronic equipment uses the safety grounding conductor ...

Specialized grounding techniques have evolved to meet the perceived grounding requirements of electronic equipment performance but sometimes also violate the National Electrical Code (NEC).

The other type is the equipment grounding conductor (EGC), which connects exposed, possibly energized conductive surfaces such as module framing, racking, aluminum enclosures, and other noncurrent ...
