on 9/13 someone posted a picture showing aservice disc. with two lugs installed on the bottom of the enclosure that had a green gec and another black gec.because that enclosure comes with only enough lugs for the 2 neutrals and the egc to the feeder panel,you have to add a lug either inside the enclosure using the pretapped threaded hole or scrape the paint on the outside and attach the lug with nuts and bolts or a 10-32 tapping thread forming screw.the tek screws used in the picture from 9/13 are a violation.the installer probably would be better off using a split bolt to attach the #6 to the #4.even though the 10-32screw is code compliant i wouldn't use it for this application.
lugs used for egc

The GEC must connect directly to the neutral not the enclosure. You can split bolt the conductor from another electrode to the GEC and it then becomes a bonding jumper and is no longer considered a GEC. In the scenario that you've mentioned the EGC run with the feeder can terminate on the enclosure itself. Do you have a link to that old thread?

If there is an outdoor main the odds are even that they did not bond the GEC directly to the neutral. I don't know why they don't provide more spaces on the neutral bar.
