I just had a job not pass inspection because the inspector said I had 2 ground wires under a lug designed for only one conductor. So here is the scenario. I had to run a feeder with a #4 ground wire. At a midpoint of the run I installed a 18"x18" junction box with a ground bar that had 12 position in it, one for a 1/0 and the balance would be for up to #6. I did not cut the #4 ground just stripped back about 3" of insulation put some green tape on each side of the bare exposed copper about 6" back. I then folded the exposed copper in half and then took my pliers and squeezed the end together to make it fit into the lug for the 1/0. torqued the connection to the specified setting and as far as I was concerned it was a good install.
The inspector would not pass the install insisting that the lug is not designed for 2 conductors. I pulled the ground wire out to show him it was still only one wire but still failed. Small town not sure if he just want to show his knowledge. He would not sign off on the permit and also said he was not going to give me in writing the code violation he alleges that is present. He is required to do here in MA. Sure I know some will say to just add an approved lug to the ground bar to make it compliant. But it was the end of the day and I was out in the boonies, supply house would have been closed by the time i got to it so I just let it go. It is 2 hours one way to the site and I am not going back.
