Forget scraping paint! That's a concentric knockout hole, so you have to use an Eq. Bond. Conductor, and appropriate bonding fitting.

I'm not sure it is a fitting at all. It could be we're seeing the material that the panel itself is mounted to, and what has been cut off is EMT. ?

Back to the nylon cable ties for a minute. Have any of you out there come behind on a project where these were installed, with the tails cut off with a dykes or Kleins and done minor surgery on your hands and forearms? I know of an electrician that required stiches to close the would produced by one of these short tails.

A good practice is probably to turn the tie so the little "buckle" faces the rear of the panel before tightening it all the way. That way all sharp edges are nowhere near someone's fingers.

Don't know if anyone is still reading old posts.... But reguardless of the connector, this is a three phase residential service?
Now the zip tie thing. Up here, ( San Fran )310-15 is required. Not just for that piece of plumbing nipple they ran through, but the zip tie too!

e57, 310.15 does not apply to bundles less than 24" in length, most times in a panel you would not exceed this, are they making you apply this for all lengths? 2002 NEC 310.15(B)(2) Adjustment Factors. (a) More Than Three Current-Carrying Conductors in a Raceway or Cable.
Where the number of current-carrying conductors in a raceway or cable exceeds three, or where single conductors or multiconductor cables are stacked or bundled longer than 600 mm (24 in.) without maintaining spacing and are not installed in raceways, the allowable ampacity of each conductor shall be reduced as shown in Table 310.15(B)(2)(a).

To iwire:
Exactly! From what little we can see from this picture, ( I figure this to be a Meter / Main with distriution. 12/24 100 - 200a Breakers in a single row up one side.) The conductors could be easily be more than 24".
And, the conduit "could" run half way through the house. From the picture alone we really can't tell.
I just figured I would chime in on those upset about zip tie knicks. Maybe just iliminate them?
And, I think the original point was that none of these circuits have a viable ground.

If this "connector" wasn't 1" tradesize, I'd say it was an airduct sampling tube cut off just past the flange. The notches on the flange aren't really deep enough either to support this theory, but perhaps it's something similar. Probably a work-around for not having the proper tool to make room in the masonary for a 1" connector. I'm assuming the enclosure is mounted to masonary by looking at the tapcon, but who knows, perhaps this assumption is also unfounded. In any case, it's clearly not street legal!

Maybe that is 'METALLIC COATED PVC WITH A NEW SNAPIN CONNECTOR' (doesn't require a ground) I am sure you have all seen one, they are very common, they are UL listed under the code letters CRAP.
