seeing as we beat this horse pretty regularly around here...here is a pretty clear reference with pictures for grounding and bonding.

My dial-up delivers one electron at a time, so I couldn"t see yourpost, but a few years ago there used to be a very clear concise picture of all the grounding regs in the NEC Handbooks. Not the NEC Code book itself, but the Handbooks. Really clarified it.

You mean beat the horse to death? Some even beat their chest. When it comes to NEC decoder rings, it's like SSDD.

Whewwwwwwwwwwww lol looks like most of what I've been "preaching" on here is correct. I already had that excellent artice in my archives and its indeed a good article. Wayyyyyyyyy back in the day when we had to attend NEC Seminars I had the honor of having the likes of Joe Mc Partland and Mike Holt as instructors......

THANKS for the post it should help some of the good gents here and myself as well, Im rusty as an old nail on this having retired from active engineering design work in 1991

Notice how the neutral bars are isolated from the back boxes. . In a corrective situation when separating the grounds and neutrals the neutral bar you add must be up on plastic mounts. You are not just adding another bar and placing grounds in one neuts in another with them both still screwed to the metal back box.You want to purchase an isolated neutral bar.One thing I noticed in the pics was the ground lug mounted with a sheet rock screw and the paint not scraped off the back box Kinda bad practice.Wasn't sure if it was supposed to show bad work as the aluminum was wrapped around the copper but not landed in the lug. Good info for those who have a subpanel.

If you right click Zebs link and choose "save as" or "Save link as" you can download the pdf. It's about 4MB. Dialup should be able to download it after a while.
