OK.....I was thinking of 250.86 Exception 2. I guess it all depends on the interpretation of the word "short"
I've used them of course, but I never was a big fan of the grounding clips. Threaded screw and pigtail into the machine hole in the back of the box-yes, much better.
To paraphrase Gary Seinfeld, "Why have a box?"

yes.
in 4" square boxes (surface mount) I use a screw, in nail-up boxes (flush mount) i use a clip.
my reply was to post number two. Please show me a code article that says I have to ground the device along with the box. I'd like to see it.
Yep - them ones are the same in the '05 NEC too... Don't tell me mcclary, you're one of those who think all switches and recepticals are 'self-grounding', and don't need anything on the silly green screw on the device?2008 NEC
Receptacles 406.3(C)
Switches 404.9(B)

Well I guess it is 'this' again.... Not sure if 250.146(B) was brought up in that thread - but it is clear that self-grounding devices are listed for the purpose and required when the yoke is not in contact with the box to include removal of the little plastic screw holder... (Requiring the box or ring be proud of finish...) Otherwise the receptical yoke must be grounded with a wire EGC... And I only mention it because I often come across people from LaLa land who think otherwise.... :roll: Additionally - That somehow switches need no EGC... 404.9(B)1 is not worded as well - but I don't think many inspectors would accept a loose free-floating switch install to a metal metal box as "Effectively grounded" - otherwise 404.9(B)2 is in effect IMO....Not this again. Start reading here.
No, but they do not require removal of the plastic or fiber screw retainer. The piece on the yoke permits the screw itself to act as the conductor, and does not depend on yoke-to-box contact, which does require retainer removal.A "listed self-grounding" device yoke - like the one pictured on this receptical below are not found on many switches, and even fewer (if any?) dimmers.
Recpt.'s or switches??? For self-grounding type recept's - you would not have to remove the plastic screw retainer on the other screw....No, but they do not require removal of the plastic or fiber screw retainer.

Don't forget it (screw or whatever) HAS to be green, and not painted or sharpied green either.

Switches - while (like mentioned before) the wording of 404.9(B)1 is not as clear (true) - but a loose installation does not qualify for 250.4(A)5 IMO. The yoke is not "mounted to the box" - if anything in most cases it is mounted to sheetrock and loosely at that. Requiring a EGC IMO.
You guys install switches in a wall without a box? That just seems wrong to me.
