What is your spin on Green wirenuts? i think using them in single-gang boxes is fine because the wirenut only allows 1 equipment ground out of the top to attach to 1 device. Now in a 2,3,4, or even 5 gang, Using a green wirenut seems rediculous if all devices must be grounded. What happened to those copper crimp sleeves, that made finishing a house so nice?!!!
In my home I have avoided anything more than 2 gang in most places, just to avoid that "need a map to turn on the light" problem. In the one big box I ended up with I used one of the #10 tapped holes for a 6 hole ground bus kit. Then I used #12 stranded pigtails with terminals for all the devices. It made a very easy install. This was piped in so all the conductors were stranded with terminals. (lots of colors too)
I think Greenies are nice, but a waste of money, and one more part to keep separated in the parts bag. I use tan wirenuts for 99% of my splices, the reds, grays or blues only when necessary, yellows very seldom. (And, of course, the oranges for fixtures.)
I never used them, becasue as a commercial installer my EGC's were insulated, and I don't like the idea of having bare conductors longer than needed. If I were doin residential, however, I would have used them.
