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.

Greg:

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.

If you are looking for a UL/CSA listed product, here is this from TYCO. https://www.graybar.com/documents/te-connectivity/power-distribution-products.pdf

Looking at the documentation it looks like as Hotline1 said for use under carpet tiles only.

I don;t remember all the details, but it was an involved install, and that tenant was in and out in a few months & space was renovated.

There was a base of vinyl, the FCC, another layer of vinyl, and a roll of sheet metal over that, and then wide tape cover. It was 120 volt and data.

Nice product description in the link. One would think that a perfect translation into the English language would be mandatory when selling stuff..

This could be a fire waiting to start, UL?? You have to be kidding.

You can see my concern. I suppose a product like this could be made but I am sure this is not it.
