miller, as much as I appreciate 99% of your posts, I’m not sure how you defend your position on this. It’s simple. The ground is the only safeguard in the event that any metal item becomes energized due to an equipment defect or failure.
Our house was built in 1952. I can't tell you what the code requirements may have been then. Jim may know. Everything was wired with two-conductor cables, forerunner of romex, I guess. All the boxes, etc, were metal, and they all were connected with a dedicated ground wire, one to the other. I’ve yet to find a fault in any of it, I’ve probably modernized 30% of the home, at this point. There wasn’t a three prong outlet anywhere, (not sure if they existed at the time) so you’re on your own with the toaster, etc, but every box, switch, plug, etc, was grounded. Somebody knew it was important then. It still is.
