Hmm, sorry to be so controversial!
I looked back at some old threads and saw the discussion about push-in vs. screw terminations on receptacles, but not the twist or no-twist wire nuts. Thanks for the recap.
At risk of another international incident, I have to say that I don't much like the idea of push-in terminations, maybe because I grew up without such things here.
First time I even realized these existed was about 14 years ago. I'd not been to the U.S.A. at that time and studied your wiring in detail, but I'd ordered a lot of computer equipment from California, and rigged up a transformer to run everything on 120V. I ordered a U.S. 6-way power strip which consisted of 3 duplex 5-15 recepts. and when I looked inside it I found that these used push-in wiring.
I'm not quite sure exactly what you mean by side-wired and back-wired. Every American receptacle I've ever seen has the screw terminals on the side. Does back-wire mean the push-in type of termination?
