I would use solid bare copper. would it be ok to run a bare solid copper wire thru the conduit, would the bare copper wire short to the conduit? I just realized that this was a stupid question! since the ground bar kit would be screwed to the metal box to which the conduit is attached... Last edited by jeffrey mays; 10-13-2012 at 10:02 PM.
