My question was is it ok to run the single green 12g wire in between the sole plate and the flooring, under the edge of the wall's sheetrock? So it will be lower than the top of the flooring, in that little 1/2 inch by 3/4 inch gap. If ok to do, this will be easy for me since we are replacing the baseboards anyway.

thanks!
If you can run a separate wire to ground the receptacles, why not do it right and pull new cables. Your exception may be valid.
What does the AHJ say about this project. I believe this is where you will find out if it allowed or not. We all know the AHJ has authority over the NEC.

I see no code violation in doing what your asking. You can fish that ground wire anywhere you want as long as it is free from physical damage. I don't think it's going to get damaged at the sill plate. Rodents sometimes chew wire but that is not easily prevented.

In accordance to 250. 130 (C) Where do you plan on terminating it?

Methods for running ground wire


(going around to the other side of the dead horse to continue beating it)

>>> ... all circuit conductors must be grouped together ...

My cursory look about the Internet tonight leads me to conclude that the ground wire (grounding conductor) is not a "circuit conductor"; we all know it does not normally carry current.

Back to the topic at hand, I would just merely go right ahead and run the ground wire in the channel between the lower edge of the drywall and the subfloor if that were convenient. This channel is very unlikely to be penetrated by nails.

I'm assuming such experts would have no problem with me notching the studs and using nail plates, but if that's what I have to do then it probably isn't worth it at this point. I guess I'll call the city; probably the best move anyway in cases where it isn't clear-cut to folks in forums like this.

thanks!

It (all) depends on your geographic location. Also, on what kind of lunch that particular inspector had. I'm not trying to be facetious. But there appear to be contradictory answers in the NEC. On the one hand, it appears that it is permissible to run a (supplemental; not really supplemental. Because that would create a potential parallel path to ground.) wire to the grounding rod. On the other hand, it appears that All the conductors must be in one cable. It must be well researched to see all the exceptions. (No matter what) Don't Drink and Drive, Ever!!!
