Recommended methods for running the grounding electrode conductor (arranged by preference for
system performance; as acceptable by local and other applicable codes):
• Outside of conduit (where not subject to damage)
• Inside non-metallic conduit
• Inside non-ferrous conduit
• Inside ferrous conduit, bonded to the ferrous conduit at both ends, as acceptable by local and other
applicable codes
