This is from the web site quoted- This is how how a house I used to own was wired for the few (at the time) obligatory three-prong sockets. I was told by the house inspector that this did meet code.
Drilling into the stud space from above or below (crawl space or attic) does work. I've rewired 3/4 of my current 100+ year old house that way in the past ten years. I had gas piping for lighting, knob and tube, lead-covered two conductor, BX, conduit, and both two and three wire Nomex (as well as a couple of runs of lamp cord) when I started. I've now got two runs of BX, a fair amount of conduit and the rest is three (or 4) wire Nomex. And it's all up to code for the time it was done. >What my plan is, is to run the conductor through the crawl space and >drill into the stud space from below running the ground wire as one >would run a new piece of romex.
