According to 250-118 emt is an acceptable grounding conductor.250-134(a) again tells me that an emt raceway is sufficient for grounding a fixed piece of equipment as long as the race raceway can safely handle the possible fault current,250-2(d).So with this all said my question is this.In what situation is a wire conductor REQUIRED for an equipment ground. From what I've read in the '99 code I would think my pipe run would satisfy the equipment grounding requirements for anything from a subpanel to a motor. This isn't the normal procedure of course but what is wrong with my thinking?
Thanks for any answers. Barry
