ECN Forum Forums General Topics of the Trade General Discussion Area Raised floor receptacles

Is it permitted to installed a duplex receptacle under a raised floor and pass a cord through the tile to feed a workstation?
(This is not an enviromental air plenum)

Good question.

Is this one of those "tile" type floors like you have in computer rooms? I would think that the AHJ would prefer the receptacle to be mounted on or above the finish (raised) floor, for easier inspection/access.

If I was faced with this situation, I'd probably surface mount a J-box (or dedicated duplex box) to the tile, and attach that to the existing "sub" (real) floor mounted raceway system by means of MC/flex.

The closest ref. I can find is Underfloor Raceways (390).

When in doubt... ask your AHJ?!

400.8(2).


BTW: I'm a big fan of your music

The general answer is as stated by Ryan. There is a possibility that this can be done if you are in compliance with Article 645, and the cord is listed as Data Processing Cable.

Thanks to all, additional comments are welcome.

Good eye, Ryan!
