if it was a cheap back-stabbed receptacle it could be eventually.Nor is this a problem.
I was going to say that too, but then I realized I was comparing apples and oranges here. A good tightened screw plate pressing down on a wire is inherently more secure (and contact made better) than a quick back stab connection.No but I have seen very good "backfed" connections and prefer to use them- These are tightened by the screw on the side of the receptacle- no twisting wire around a screw necessary.
