Do not twist the wires before you put the wire in the wire nut according to
code and do not use the push in terminals on the plug and when you put the
wire on the screw wrap it around the screw and pinch the wires tight

the "code" only says follow the manufacturer's instructions and most
manufacturers (Ideal, 3M )say "it is not necessary to twist" They do
not say "don't twist". It is really up to the installer. You can get a
good connection or a bad one either way. That is where skill and
experience come in.
I agree with the old-timer and tighten with the screw. I have had push
in connections. I think they have failed most often in my case, where
the wife use to plug a vacuum in regularly.
"Well, it doesn't happen all the time, but when it happens, it happens
I suspect they're okay for the terminal junction.
But look how they work. Like an alligator clamp.
If several outlets are daisy-chained, the final current draw on the first
plug-in may be significant - and greater than the miniscule contact area can
handle. This results in charring, overheating, and (if you're lucky) loss of
I've never seen how they're constructed internally, so I can't say anything
for sure. But it seems like losses in a circuit due to bad connections
would be measurable and testable.
I know I have seen a lot of wire nut connections that seemed firm - until
the wire is twisted as it's being pushed back into the box. That's one of
the bigger advantages over wire nuts that I saw there - unlike a wire nut,
the push in connector has all the wires in a line and easily routed out of
the way back in the junction box.
Go to HD and buy a cheapo outlet with push-in connectors ($0.39). Whack it
with a hammer.
Now you can see the miniature speed-nut that is the electrical connection.
Put 15 Amps through that teeny surface area and you've got molten brass.
Yes, and 35 years ago the electricians
used aluminum wire with the "stab in"
outlets in my neighborhood. Many have
had electrical problems, even fires.
I was lucky. They started learning of
the problems. In my house, the still
used aluminum, but used the screws. I
have pigtailed copper to these and
have never had a problem. Houses built
a half a year later than mine, used
the special switches and outlets rated
for aluminum. Houses built a year or
2 later, didn't use aluminum for branch
Purely option, of mine and asking others. The dislike I noticed comes
from bad results from 'backstabbing' receptacles and switches. So
these connectors have to overcome past dislike.
I don't like them because a tan wire nut will handle so many ranges of
wire combinations, and number of 14# wire (1-5).
Just my option, and my observations.

I just used them in a junction box for my bathroom remodeling
project...seemed very secure and i liked the fact that they wires were
easy to tuck back into the box.
I did dissect one of them and it seems it is beefier and more secure
than a stab-lock fixture might be...there is a hump that the wire has
to ride over which increases the contact with the "fingers"
I bought a halo new construction lighting can to go over my shower
(with a shower trim, of course) and when I opened the J-Box on the can
lo and behold...push in wire terminals.
I do like the fact these have a port on them for checking continuity.
I dont forsee an immediate problem with these connectors...
funny story when i was learning house wiring in electronics I had a
teacher who would yank the wirenuts on our connections VERY hard..and
if ONE nut gave..he cut all the wires and said "DO OVER".
Now in my home wiring I am just about as anal about tight
conenctions...I tighten those damn nuts up so tight that a few times
the plastic has seperated from the cone...these are Buchannan wire nuts
I am talking about here...
Well I did the same "Yank Test" on these push on connectors and those
damn things didnt budge...irregardless if it was 12 or 14 guage wire.
I feel pretty confident using them..
