Floor mounted Electrical outlets

Building out a new office on the 1st floor of our house and I have a full basement below.

I need to install an electrical outlet beneath the desk and I am thinking of installing one of those brass electrical outlets that I have seen in concrete floor and drop floors. Any Internet links on how to do this? I have done quite a bit of electrical work in the past just never floor mounted outlets.

Has anyone ever installed floor mounted outlets? Any specific code I need to know or worry about?

How hard is this? What did you use to cut through the carpeting & padding to get to the subfloor - I would prefer to not pull up the carpeting as I am not very good installing carpet.

Rasguy, the floor outlet box must be one for a floor mounted receptacle. As for the carpet , nothing like a carpet knife or utility knife to give you access to the subfloor......RL

There are several types. One I have used is a full assembly made by Lew. It's the round one with a duplex receptacle and is the nicest and toughest. You can get plastic or brass carpet flanges to finish off the edge with your carpet.
This one is the more difficult to install though. You need to hole saw a hole in the subfloor. Luckily with carpet you only need the one size hole for the box itself. Then you cut the carpet around the box flange and install the carpet flange. With hardwood you need to cut a "stepped" hole. One size in the subfloor and a larger "recess" in the finished floor.
The other is just dropped receptacle and a cover plate with a closure plug. This fits in a standard deep gem box. The drawback is that the cover is sometimes stamped brass and some are only a single receptacle.
The ones from Lew are the nicest whichever you go with. Not a Depot item though. From some of your previous posts I see you as much a fan of the big stores as I am. Lew Electric Fittings
