panelboards

I'm know that the main panelboard must have the grounded system and the grounding system bonded, and that at subpanels they must be isolated.

But for the life of me, I can't find the code section to reference it.

I believe the requirements are in 250.6(A).

Bonding the neutral to ground at the sub-panel will create another path for the neutral current.
