I have always hated seeing outlets that had the wires in the back instead of on the screws, but I have seen a new (well, somewhat new) type of backwire, where yu put the wires in the back and tighten the screw and it holds the wire securely into place (and has more surface contact area - i took apart a GFCI with this kind of connection). I would lke to know, whether opinion or study, how safe this is compared to wrapping the wire around the screw (assuming wire is Cu and the proper gauge)
... In my honest opinion,they should stop producing the back-stab,spring loaded connection,I can't believe UL lists that method as a sound,good connection,...and use only screw terminals,or..back-wire with screw terminal compression,like in the GFCI's as previously stated. Russ

I agree with Russ, I think they should stop making the back stab recpts. Just yesterday, I had to go to a neighbors house to troubleshoot a problem with a room of recept. not working. Once again, the back stab connection was the culprit. I've found this problem over the years more than I can count. This time the wires had burnt in the back of the recpt. I've found them both ways; just loose in the back of the recpt. and also burnt up in the back. Years ago when aluminum was on the "go", it was really a bad fire hazard; seen them really destroy the wires and recpts Steve

I'll pretty much go with everyone else here, The backwire outlets seem to have a much higher failure rate in general... the amount of surface contact on the connections is too minimal IMO.. I pull out backwire outlets all the time & the wires just pop out .. The outlets with the pressure plates which you tighten down via the side terminals are built much better & these are what I generally use (P&S BR15/20) I've never had a call back on them yet... Tom, I've never come across those outlets yet, they 'look' pretty well built...
i wire we have several tubs of these show up at work some of the guys like them i personally dont, but in checking them i dont find a list/label for stranded wire, am i just missing it or has the label changed i the last year. guys like them for the rotozip repais so common on agressive cuttin boxes.....(gotta love the roto zip) As for me personally we backstab only one brand of device(by bosses orders) if its not brand X then it gets the screw terminals i remember the old ones rated for 20 amp and remember doing a lot of R and R after they melted i dont mind them on brand x for a 15 amp. but im leery of the 20 a on the ideal setups
