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)
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?
As a general FYI, both NEC and CEC requires that all conductors for a circuit
are "together". Ie: same cable sheath or same conduit or same raceway etc.
Idea being that subsequent renovations don't leave you with something really
wierd. Neutral on wrong circuit. Etc.
Haywiring grounds (ie: separate grounding retrofits in old houses) is an exception
that the inspector will usually permit (depending on what the other end is attached
to). Ditto certain kinds of K&T fixes.
You could never do K&T techniques now, no matter what you used for wire, because
of these rules.
