With the standard light load of most 15 amp general receptacle circuits in a dwelling, back stabbing is not a problem.

I have had service calls on all types of receptacles at one time or another, and in most cases it was evident the installer was the real problem, be it not tightening a screw, or not making sure the wire was inserted properly.

I must say a screw or pressure plate type installation is my preferred method, but I have back stabbed devices in my own home that have never given me any problems, and yes I installed them. [Linked Image]
