Grounding Electrode Conductor

[egoy]

I recently inspected an installation of a separately-derived system. The N-G bond was made in the panelboard rather than the transformer. The GEC went out the bottom of the panelboard in the same conduit as some circuit conductors. The GEC broke out on its own at a junction box below the panel and went to the grounding electrode. It seems to me that the GEC should not be installed in the same conduit as other circuit conductors, but I can't find anything in the NEC requireing this. Can anyone help?

Thanks,
Eric

Eric,
I see no reason why the GEC can't be in that raceway. Just make sure that the bonding required by 250.64(E) if the raceway is metallic.

I agree with Don.

It seems to me that the GEC should not be installed in the same conduit as other circuit conductors

And depending on their size, GEC's are not even required to be in conduit.

Maybe what you are thinking of is that the service conductors cannot be in a raceway with other conductors. The GEC is not a service conductor.
