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.

This is one of the products they were recommending

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.

324.12(4) states that flat conductor cable shall not be used in residential, school, & hospital buildings.

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