I saw this today. Most times I see neutral and ground on the same bar but different lugs. This panel has about 9 on the same lug. Is it acceptable?

this may help you (I believe someone posted this a while back)
Is it the entrance panel, or a distribution panel? Distribution panel must be separate bus bars; one neutral grounded conductor to one terminal screw; grounding can be doubled.
Lugs, Bugs, Bars, Oh My.
I’m getting the sense there is a miss communication going on here since there is a terminology mix up.
I believe the OP is asking if Equipment Grounding Conductors “Grounds” and Grounded Conductors “Neutrals” can be on the same bar? Even though they are under different terminal screws (what I think the OP is calling lugs). Under certain conditions this is ok. However, you compound two questions into one paragraph, and mention you see one with 9 ‘somethings’ under a ‘lug’. huh?
Rather than explain what you meant, a photo would be nice.

It was clarified here. . .
Ah, there is the photo I was looking for…
