Is there a listed flat cable solution that can be used under a carpet. Amazon sells one but I do not see any reference to it being listed. I bumped into this on a homeowner BB and I did not address it. The object is to get a receptacle in the middle of a room without trenching the floor.
AFAIK, the onl listed use of flat carpet cable is under carpet tiles, not ‘one piece’ carpeting. (Commercial)
I guess one could request a variation from the AHJ. From my experience with tools, it is a PITA on the install. I last did it in a few offices for conference table locations in lieu of cutting the slab.
To me, this just doesn't seem like a good idea, even under carpet squares.
It always reminds me of when I worked for a Moving Company and we regularly had to wheel dollies with full double-wide File Cabinets across them. I don't know what they weighed, but I'm guessing over 1000 lbs. We did mostly put down sheets of Masonite to keep the squares from popping up, but I still think there might be a chance for cable damage below.

Looks like the '17 limited it's usage even more.....?
