No-name hardware store variety.

My home-made power cord is based on the Volex shielded 14-gauge with lots of treatments. This particular cord has a hardware store replacement plug chosen because it has a rubber body, no steel parts, and heavy brass blades that I could remove. The wires were soldered to the blades separate from the body so that I could get good solder joints without melting the body.

Right before this experiment, I polished the blades with 600-grit wet-or-dry sand paper, Brasso, and cleaned the residue with Kontak.

I agree the results are plug-dependent, and different plugs have different plating recipes. Keep in mind, though, that the same plating materials used on the outlet receptacle blades are also present where the copper house wire leads are clamped to the outlet. Thus, the plating interface with pure copper is an unavoidable part of the outlet circuit.

Replacing the plug is a future experiment, and something I will have to think about.
