His corrosion issue may not be copper oxide, but a mix of various copper sulfate, chloride, or chloride salts, which turn the wire green. That is less conductive.
Yes, the green one. I have seen the plastic in the plug of a stove or heater melt away due to bad connection between the cable and the plug. And the issue was worse in the period when I lived in an old place in Madrid with 110 volts AC than at home, with 220V. When I opened the things I saw that green oxide or salts or whatever. Oxide, acting as semiconductor, causes a voltage drop of at least 0.1..0.2 volts. At 10 amps, that's 1..2 watts, that heat up the connection. - -- Cheers / Saludos, Carlos E. R.
