Situation: conductors run through conduit from service equipment to a subpanel. There is an appropriately-sized disconnect in the service panel.
Question: Does the NEC require that the equipment groundING conductor be run through the *same* conduit as the groundED (neutral) and ungrounded (hot) conductors?
I am unable to find any place in the Code where this situation is addressed, either permitting or prohibiting it, whether explicitly or implicitly.
Can anyone help?
