UnderTile Cable

[Castrovinci]

Hi All,
I have an application in the mall where they will not allow power poles, and due to the config and location core drilling and going into the first floor ceiling and back up to the second floor is cost prohibitive. Does anyone know of any cable where we can bury directly under new tile. Like a heated mat, without the heat. I have heard of a mineral insulated cable, but have never worked with it and it is approved to go under tile? Do you know any restrictions?

I don't think that MI cable is suitable for your application. There's flat conductor cable, Type FCC in Article 324 but that's designed to go under removable carpet squares. You cannot cut/chop a small groove and install a raceway like 1/2" or 3/4" EMT?

If you put EMT in a groove in the floor, do the cover requirements come into play?

Not the ones in T300.5. Just chop it shallow enough to get the raceway in and patch over it.
