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.

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. [Linked Image]

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...." [Linked Image]

that looks like a new ungrounded receptacle... why would they still make these? [Linked Image]

Matt,
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
Edited because im in YIM mode and abbreviate everything
