I found this in a friends house a three way lamp was plugged into it. It works and is wired right But this is probably a violation.

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.

This probably has a plug on the other end of the zip cord. In that case, does NEC apply?

I don't understand, why not get one of those plug-in table top dimmers where you plug it into the wall, plug the lamp into the through-tap and there's a cord with a dimmer switch at the end?

Alternatively, you can get a dimmer switch that attaches to the lamp's cord like a regular on-cord switch, except that instead of a rocker, it has a knob that you turn with your thumb.

Either of the above solutions would have been simpler, cheaper and safer than this kludge that Peter shows us.

EDIT: Also, those boxes are not listed for that type of portable application. The metal ones have knockouts that can break off and the plastic boxes will shatter like a phonograph record if dropped on the floor, kicked or banged.

I definitely agree with the issues concerning durability, and I don't like the idea of this thing getting knocked around by that piece of zip-cord with no gromets or strain-relief to speak of.

But on the plus side, at least they had sense enough not to use a grounding-type receptacle and what appears to be heavier-than-normal 16 gauge lamp cord...

It's pretty bad when I look at something like this and think: "Well, it could be worse...."

that looks like a new ungrounded receptacle... why would they still make these?

Ungrounded receptacles are still made for situations where there is an existing ungrounded receptacle needing replacement. Instead of replacing the receptacle with a GFCI, you can use one of these. However... they are sold at "home centers" and the last time I looked, El Cheapo outlets from the big bin were about 40ยข, while these cost over $1.50. It's likely that the NEMA 5-15 outlets are used with nothing connected to the ground, instead of using these 1-15's
