Routing feeder equipment grounding conductor OUTSIDE of conduit?
Routing feeder equipment grounding conductor OUTSIDE of conduit?
(OP)
Where it is desired in existing facilities to add an equipment grounding conductor to an existing feeder, is it allowed to route the equipment grounding conductor OUTSIDE and strapped to the existing conduit. If not, WHERE is this specifically prohibited by the NEC?
Article 250.118 discusses the equipment grounding conductor routed "with" or "enclosing" (metallic conduit path is conductor). I see nothing in the code that either allows or prohibits augmenting an existing feeder w/ an equipment ground conductor.
Thanks

We have someone in the field now tracing the conduit to ensure it is all 2.5" and either EMT or rigid steel.
Thank you both for the input.

You may help the owner "swallow the pill" by pointing out that copper theft is rampant and that he could easily have an exterior hung wire stolen. Inside a conduit protects it from not just accidental damage but from much more likely - theft.
