Re: dimmers connected to receptacles
No. NEC 404.14 (E) Dimmer Switches. General-use dimmer switches shall be used only to control permanently installed incandescent luminaires (lighting fixtures) unless listed for the control of other loads and installed accordingly.
One example of the "other loads" is a kitchen exhaust fan. I have one installed in my kitchen, and the dimmer is listed for that specific load. A general purpose receptacle would not qualify, because the listing of the dimmer could not explicitly include every type of load that could be plugged into the receptacle.
(Looks like Don and I posted our answers around the same time. But at least we did not disagree too severely.)

wounder what would happen if that new 32" plasma screen tv was plugged into a dimmer controlled outlet.

Re: dimmers connected to receptacles
This is my first post here, and I'm bringing up an old thread on 404.14(E)... I guess what I don't understand is, can't you plug some other load into that kitchen exhaust fan receptacle? Realistically, couldn't you plug anything into any receptacle? i.e. what's stopping me from plugging in a car to a receptacle instead of an appliance (this may not be the best analogy, since a car would be running on DC, but you still have two terminals that you could wire into a standard plug). My understanding was that prior to these changes you could just label the outlet "lighting only" and you'd be ok. If someone has a lamp that can't be wired directly into the wall that they really want to dim, is there not some way to make it clear within the code that only this type of load can be plugged in? What about some way that would lock the load into the receptacle so that it could not be removed any more easily than rewiring the entire receptacle.

I guess I was right, there is a way: Lutron Fixes 404.14(E) Problems!

schalliol-
The change in the 2002 NEC was not really a change as the dimmers had to be installed per 110.3(B), the dimmer instructions would not allow this. It was added to the NEC as many electicians did not read the instructions and AHJ's had to write unnecessary violations

Re: dimmers connected to receptacles
I tried connecting a dimmer to a receptacle circuit several years ago, and when the homeowner tried to vacuum, the dimmer would burn out.
I tried posting a reply earlier and the message didn't show up. The luck of a first time user.

Re: dimmers connected to receptacles
Csn you tell me where this is listed in the 1999 NEC....just want to check something on the wording.
We are not using the 2002 NEC in VA so where is this info on the dimmer on a receptacle in the 1999 NEC edition.
