    Convenience. Many terminals with few threaded holes in the enclosure.

      It's not, however in your example you could only have one EGC under the screw.

        Umm, multiple ground wires maybe? It's not required but it does make the job a lot easier. What would you rather do, drill & tap a bunch of holes for ground lugs or screws or just one to mount a ground bar that could take up to a dozen ground wires?

          Not required. Who says it is and what is their reference in requiring so? If a local rule then I guess you have no choice, NEC doesn't require it, it is just convenient in many cases.

            Maybe we're talking about in a sub-panel?
            I can build anything you want if you draw a picture of it on the back of a big enough check.

            There's no substitute for hard work....but that doesn't mean I'm going to give up trying to find one.

              I assumed we were. Where does it say you must have a "ground bar"?

              You can't land grounded and grounding conductors in same place beyond service/first disconnecting means of SDS, but there is more than one way to connect EGC's, a bar just happens to be a fairly convenient method, especially if the cabinet already has a prepared location to mount it.

                It occurs to me that The Ground Bar would be a good name for a drinking establishment catering to electricians.

                    Is that grounded or grounding?
