ECN Forum Forums General Topics of the Trade General Discussion Area Sidewire vs. Backwire...

From an informed DIY'er, a question for the pro's regarding the use of push-in connections on receptacles compared to screw terminals. I personally never use them ( push-ins), I don't trust them, and I can't be sure of a solid connection, visually. Should I continue to avoid them, or is it a personal thing?

I'd say 99% of electricians don't back-plug. The other 1% are in tight competitive markets and are hoping the connections last the mandatory one-year warranty. Then it's a service call. I worked for an outfit once that gave me that very excuse, almost verbatim. I didn't work for them long.

Loose wires cause fires...

However, back wired receptacles are OK (and preferred by some) which differ by having the screw tighten the clamp rather than a spring. These are common in GFCI receptacles.

Thanks for the quick reply...I figured as much. As for the GFCI's, I've found that with many manufacturers, that's the only termination they provide.(back-wire) I really like those-a positive, tight connection.Incidentally, does anyone out there know if the NEC code re AFCI's will (or is) be applicable in Canada?
BTW, I am in Toronto.

Let me admit I might, occasionally, "push-in" a switch to control a lower wattage fixture(s) on a switch loop, or if I'm jumping to a second switch in the same box. They are UL listed as such. Sorry!

mickky,

Welcome!
We have several very knowledgable people that are familliar with the Canadian Codes. If you have anything specific code-wise for Canada you should post it there and they will see it.

Redsy, I only use pushin connections when I have two line outs on recepticles. To me its much cleaner than a pigtail. Tell you the truth though I've never had a recall on any pushin I've done. But have seen others fail.

When I use pushins I always give a little tug to make sure of a good connection.

As far as GFI's the munufacturers have got a good thing going in my opinion, I like the screw down clamps they are using.

Just say NO to push in connections! They will fail when heavily loaded.

Resistor,
Are you saying that you don't pigtail??

I'm not a fan of push-ins, but if they are that bad, how do they get listed? Arent they rigidly tested within their rating?

I've installed outdoor lamps (pedestal type) that had no box containing a splice in a teakwood frame, a typical porcelain keyless screwed to the wood, and this was a 120V light, 100W. The bulb was within 6" of the teakwood lid... No heat insulator of any kind... It was UL listed. They were very pretty when the lid was closed, however...

I'll only install UL listed devices, (that are listed for the purpose)... but I won't fall for the idea that UL equals OK...

Besides... the 1875W hair dryers with 15A plugs are UL listed... Need I say more?
