motor-T,
Go to "www.wago.com". The site has a button that takes you to a PDF brochure for the "wal-nut" connectors.
I saw 'em at ElectricWest last year in Anaheim and got a few. I was doubtful about the quality of the connection, but it's really pretty good. It's not cheesey like a back-stab device; on the wal-nut, there's a lot of wire-to-connector contact. And the thing really grabs the wire.
Now, I wouldn't use the WAGO for splicing in a a receptacle circuit except in a real pinch. But sometimes for old work where the conductor is cut off inside the box, they're a lifesaver.
If I'm doing commercial lighting circuits and my margin is real slim, I sometimes use 'em. No problems so far.
Ideal Industries makes a very similar product, but it's not designed for stranded conductors. The Idea product is easier to find, though. I just call them WAGOs, regardless of the source.
