electricaloutlets
If I am able to lower an electrical box by a few inches, I will have enough wire to avoid having to use a junction box to splice a nick I made in the insulation of the neutral wire. It's only a three-foot wall section and will be the only electrical outlet there, so it won't look too odd being slightly lower than the others in the room.
I've Googled this a bit, but all I see are lengthy discussion threads where people are simply not sure. Is there anyone who has the straight answer on this?
Tyco makes NM splices which are concealable and acceptable under NEC for use for rewiring in an existing building.
NEC 2008
334.40 Boxes and Fittings.
(B) Devices of Insulating Material. Switch, outlet, and tap devices of insulating material shall be permitted to be used without boxes in exposed cable wiring and for rewiring in existing buildings where the cable is concealed and fished. Openings in such devices shall form a close fit around the outer covering of the cable, and the device shall fully enclose the part of the cable from which any part of the covering has been removed. Where connections to conductors are by binding-screw terminals, there shall be available as many terminals as conductors.
We can't post what is not there. There is nothing prohibiting this and as Tester states, quite a bit of chapters 1 thru 3 apply in general, with spots in 4. The NEC is NOT written in a way that you can simply look up a specific job you are doing. It can be very general and very broad, yet also specific on certain things.
I realize this question is 3 months old and the project likely done by now, but what is being proposed in the original post is fine.

I wasn't able to find anything that limited the height of receptacles, in fact, they can even be in the floor.
I think typically they're between 16 - 18", but it doesn't look like there are any hard set rules on this for general purpose receptacles (at least as far as NEC is concerned).
