If I was going to put carpet on a wall I think that I would install some sort of backer board behind it such as sheetrock, plywood, ect. To install carpet by itself would make for a flimsy wall or a floor that I would fall through.
I ?think? that the protection outlined in 300 is for the fasteners that hold the wall board. There is no way that the code making panels can assure the protection of electrical equipment after the final inspection. The home owner is the ?authority having jurisdiction? at that point.

JW remember we are talking about a solid masonry wall, not a stud wall.

A typical movie theater for example will have carpet glued directly to the masonry.
 
Re: Arnored Cable

Now I have to deal with this same inspector on the installation of romex above 3 stories.
150 unit condo 5 stories high

The approved plans call for Bx cable for branch circiut, and copper risers rated for 100 amp @ 75deg C.

I told the developer after signing the contract that I can save him some funds if we went with Romex and SER Alum. risers rated the same.
He got a woody :)

The inspector said no because the approved plans are for Bx Etc.....

Another battle awaits me !!!!

Why are we so close minded as to only think of shag glued to walls? There's no limitation in the code only to walls. Carpetlayers around here use tack strips nailed to the floor in the corners. :D
 
Re: Arnored Cable

Interesting that the AHJ sided with you......congrats on your outcome with this .

My concerns would be of some wheres along that 6000 ft. of block wall something is going to get anchored into it sooner or later .....

like a fire extinguisher cabinet / bracket, hand railing or something along those lines.

You have won today....... but for myself I would check before doing a project like this....
my worrys would be that the end results may not be the same as yours .
 
Re: Arnored Cable

mrmax. Is the groove wide enough to cover the MC with wiremold and the plaster over the wiremold. You could use adhesive to secure it. I know this sounds like your getting a hack method but sometimes you just have to be creative. :confused:
 
Re: Arnored Cable

Bob,
what is the need for the nail plates under carpet?

I haven't seen a lot of carpet on walls, myself. But I understand glue.

Think about all the drywall that has been glued to walls. In my experience, the rockers never use a jig to hold the rock in place until the glue sets, rather, they fasten it with screws or nails. I suspect carpet, if glued, is handled similarly. All but the flimsiest of gossamer carpets would weigh too much for most adhesives until cured.

Going back to my illustration using notches in wood studs in an existing wall points, IMO, to the inconsistancy of 300.4. There is no unified field theory here.

Lastly, this underplaster extension permitted use is also part of 330.10(11) MC, and 332.10(6) MI.
