Copper oxidizes. And this makes a bad contact, when two wires, or wires and connectors, join. A slightly bad contact heats up just a bit, which in turn increase the speed of oxidation, which then becomes worse and worse. You notice this first by plugs becoming warm to the touch, then hot, then melting the plastic.
Actually, you've just describe a problem with aluminum wire. Copper oxide is actually a fairly decent conductor, well semi-conductor, so that problem doesn't occur that much.
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. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
