Grounded Conductor Connection

[Little Bill]

I'm having a brain lapse and can't find a code article/requirement. Where does it say not to use a cabinet for a path for the grounded conductor? After I find this I have something else to find that supposedly changed in the 2017 for the EGC in a cabinet.

Its in that article I always forget exists: 200.2(B) 2014. Not sure if its the same in 2017.

All I can find right now is 250.6(A).

Aha! I was looking in 250.

I just found it and was about to post when I saw this!

The reason I was looking is I had an inspector tell me that because I added a ground bar to an existing panel that I had to run a jumper between the two ground bars. These were not neutral bars, I had to separate the grounds and neutrals because I installed a service rated transfer switch and it made the existing main panel a sub panel.

I asked him why was that and he said it was similar to 200.2(B). I told him that was for current depending on the cabinet for continuity not the EGC. He said it changed in the 2017 but couldn't tell me exactly where it was. All he said was in 250 somewhere!:rant:

There are many mentions of continuity in article 250 but none states what your inspector is saying. We attach the equipment grounding conductor to boxes all the time which in term get connected to another box via conduit and then attached back to the box.

If that change is there I would demand he show it to me
