Just curious if this practice is still out there. Recently talked with a new hire who has been trained in this fashion. Thought this went out back in the 90's.

I back stab all receptacles and have no problems from it.

I also backstab using pigtails, which I think is the more important part of the circuit.

Can't say that I know the law on this but the bottom line is that backstabbing was okay for just the convenience outlets that were typically for a lamp, or such device. These days when we are using extension cords and drill motors that can cause heating up of the contact point in a backstab application it causes a deteriorating effect on the metal in the receptacle. The metal heats up and over time can warp and the loose connections occur and the arc fault breakers trip.

There are still transformers with PCBs, and asbestos covered pipes as well. Bring your new hire up to speed. Back stabbing a receptacle gives you very little contact surface and will cause the connection to heat up under heavy loads.

aren't those contacts tested in a laboratory...

Yes they are. Which makes me wonder: Why can't you also stab the ground?

maybe the fault current would be to high for a back stab plus it is probably cheaper to just add lil piece of threaded metal then to an extra back stab feature..

I still see it but I don't do it. IF CMP had brains they would out law it... But that's what the AFCIs are for. :no:

If it's UL listed/labeled to backstab, then it's perfectly acceptable, no matter what an electrician's personal preference is.

 

[Magnettica]

Only a loser back stabs their receptacles.

I wonder why they did away #12?:whistling2:

 

[RGH]

ok i'll bite......:laughing: backstabbing provides work down the road.....just say'in:whistling2:....and that's All I am sayin..

it probably cost more to manufacture 12 slots when most of the wiring in a home is 14....just my guess..it all boils down to money...

In a typically wired residential kitchen, I would be leery of a 1200 watt broiler feeding through 2 or 3 other backstabbed receptacles.

 

[bkmichael65]

My comment was just that it's a compliant installation. I personally think it's a cheap and lazy way to work. The manufacturers are trying to cater to contractors trying to save a buck on labor at the expense of a quality installation

 

[J. Stedman]

No back stabbing here. :no:

 

[phil20]

i never backstab but im sure i do something somebody else hates lol

Supposedly of preventing backstabbing old aluminum, but where you see 12 you see the most loading. And the most failures of back stabbing occur on heavy loads where the ooutlet goes under constant heating and cooling.

One of my old houses managed to loose several outlets in the kitchen, pull them out and I find backstabbed #12:no:
