Interesting that the installer doesn't know hoe to use a (plastic) trowel.

I'm going to wire my whole house in flatwire! Have you ever played the game operation?

That is type FCC cable covered by Article 324. It has a grounded metal cover over the top of the conductor cable. The cover was heavy enough to prevent most damage to the actual conductors. I did one install using the product and was made by Wiremold. It worked well for an open office layout, and they also had flat phone and data cables so you could get everything you need to a desk that was not near a wall.

The product in the video is a concealable non-metallic extension.
Quote:
382.2 Definitions
Concealable Nonmetallic Extension. A listed assembly of two, three, or four insulated circuit conductors within a nonmetallic jacket, an extruded thermoplastic covering, or a sealed nonmetallic covering. The classification includes surface extensions intended for mounting directly on the surface of walls or ceilings, and concealed with paint, texture, joint compound, plaster, wallpaper, tile, wall paneling, or other similar materials.
The product is in the UL White Book under "Concealable Nonmetallic Extension (PXYC) and the white book says the following:
Quote:
This category covers assemblies of two, three or four insulated circuit conductors within a nonmetallic jacket, an extruded thermoplastic covering, or a sealed nonmetallic covering. These assemblies are intended for installation in accordance with Article 382 of ANSI/NFPA 70, "National Electrical Code." These conductors are intended to be mounted directly on the surface of walls or ceilings, and concealed with paint, texture, joint compound, plaster, wallpaper, tile, wall paneling, or similar finish materials.
Concealable nonmetallic extensions of a multilayer flat conductor design, including one or more ungrounded conductors enclosed by a layer of ground conductors (inner sectioned layers), and an overall layer of ground conductors (outer sectioned layers). All flat conductors are copper and are equivalent to 14 AWG or 12 AWG conductor sizes. The starting/source tap device for the extension provides the following protection for all load-side extensions and devices:
1. Supplementary overcurrent protection
2. Level of protection equivalent to a Class A GFCI
3. Level of protection equivalent to a portable GFCI
4. Line and load-side miswire protection
5. Protection from the effects of arc faults
There is one company, Nexovation, INC. that has a product listed to this standard.

I've used flatwire in commercial applications. 120v. It is a fairly simple and clean installation.

You lay a rubber vapor barrier down on the concrete floor and tape it down. You lay your flat wire out and tape it down. You then install thin sheet metal on top of the wire and vapor barrier, and then tape that down.

Bases for receps are installed under the wire (so it can be one long continuous piece) and then carpet is laid down. The floor guys cut out around the recep bases and you just screw the recep down onto the base. Everything is proprietary and designed for the application.

It gives a nice clean look and still allows stuff to be powered without power poles everywhere.

The carpet must be carpet squares no more than one meter square.

I'm thinking of troubleshooting issues and thinking it would be a pita.


No , I am the last to learn . Under Carpet , I have worked with many
moons ago . Never seen that , and not interested .

Looks like a way way longer install and finish process than simple fishing
procedures . Way more $$$$ .

Hope some one later hangs a picture ... I do not like it .

Are they going to paint the whole wall or room ? Spot paint ?

This product is listed , I just back read some post ... GFCI will not
make it better. The AFCI people must have a hand in this .

Yes sir. Pretty much every commercial job I go to the carpet tiles are about 2' square or maybe 3' square.

I've never been on a job where they used rolls of carpet. Tiles all the way.

The circuit conductors are sandwiched between two outer copper sheets, the GFCI protection is part of the listed system, and is to de-energize the flat conductor when someone drives a nail into it.
