I'm with
Hotline on this part
If it's the main panel, with the main disco, then that's where the neutral is bonded to the ground conductors, correct?
If you are adding another termination bar (neutral/ground) the bar you are adding should (IMHO) have a jumper connected to the "factory" bar. The "jumper" should be sized according to the incoming neutral that is connected to the "factory" bar.
and this part If it's a sub-panel, then there has to be a "ground" bar, and an "isolated" neutral bar, with a "ground" and "neutral" conductor for each.
but I'm not so sure about this part NEC proposal for the number of spaces on a noodle bar?
