I think you guys are right on this. I hope the fine folks of FPE can forgive me. I always wrap a solid wire around the screw and use the clamp on stranded. This had the solid wire using the clamp and as I recall it wasn't in the receptacle when I pulled it from the outlet.

Your experience is that the increase in resistance will melt the receptacle and conductor at under 20 amps?

I concur about the quality of P&S. I started using it a few years ago and never went back.

This was not fed through, it was the end of the circuit.
