Surfinsparky, The GEC can be insulated but, Must still be bonded when it leaves a metal raceway. 95 % of fault current will be carried by the conduit not the wire. (Soares) Arcing at the end of the conduit could cut the GEC. leaving no fault path. Alan-- There is another photo of this in the Violations Photos "Store Wiring" showing an insulated GEC clamped with an NM connector.
