Quote: Originally posted by CheckItOutThis is a subpanel in a 1966 house. Neutrals are on buss bars. All of the available bars are tied together we can't just add grounds to bars the neutrals are on. Grounds are connected at a variety of places including under one of four screws holding the buss/breaker assembly to the panel box. Another example is a bunch of wires twisted together that are too short to reach a connection point so another wire is twisted to them and placed under a screw. Is the proper ground wire attachment point the lugs on either side of the box? Just stuff a bunch of wires under the lug and snug? Click to View

No. The proper attachement point would be an accessory grounding terminal kit.

What Jim said. Here's a couple of pics. The Cutler Hammer bus bar shown here allows the grounding wires to be spread out, two to a hole, but I see older Square D's that tell the sparky to twist them together and jam them into a big lug. That was then, this is now.
I suppose it depends on the panel brand and the vintage, but the best fix of course is the long bus bar with plenty of connectors.

BTW, those feeders from the main panel are kinked, so I would have the electrician check them too. There's a max bending radius for those conductors.
