We want to protect an insulated #6 THHN with 1/2" EMT instead of PVC. Will running an insulated ground wire through EMT choke the current if it does return on that wire? I know if it is bare, EMT should not be used.
Thanks Tom, The insulated #6 is for a jumper that will go from a satellite dish grounding conductor to the building electrode. To tie the two grounds together for article 810.21(J) Its one of those ground items that does not come up very often, but we want to do it to code.
