I'm stuck with saying it's a "Grounding" conductor. It is used to ground the system. It is a Grounding Electrode Conductor. It is not a grounded conductor as discussed in Article 200. I guess that's why we have this forum to resolve these issues ha ha ha. We are not talking about any branch circuits, or feeders or Service Entrance Conductors we are talking about the GEC and I say it could be bare if that's what you choose.
