Recently I was ?shot down? on an inspection by an Electrical Inspector in the county in which I work as a result of what he says is an incorrect installation of a few of my EMT connectors.
The problem;
When I installed the conduit run, the EMT connectors on one side of the run did not sit flat onto the cabinet. The locknut sits at ~1/8 of inch above the cabinet on one side and touching on the other side. The Inspector claims that since the conduit is used as a EGC, if a fault condition occurred on that circuit it would create a high resistance fault and would not clear the fault quickly. My argument is that as long as the connector is tight, even though the locknut is not fully touching the surface of the cabinet, then I have fulfilled the requirements of the NEC, 358.56. The Inspectors argument is that the connector is not ?Listed? for that purpose (must be installed so that the connectors sits flat against the metal cabinet).
I?m I correct in assuming that this installation is code complaint?
