What causes copper wires to turn green or black in an electric panel?
Normal oxidation darkens copper gradually over years, and this is observable in copper water pipes as they age. But overheated copper wires will form a dark-gray-to-black oxidation patina
My copper wire has turned black. Is it still ok to use? It
The black is cupric oxide. The corrosion to which you refer is likely copper carbonate. Cupric oxide has much higher resistivity, but it is only a surface layer. It has very little effect on the wire ampacity, but
Why is the copper wire in my cable black? | Prysmian
Sometimes, the copper wire in a new cable may have a mottled black surface when the insulation is stripped back. The black substance is most likely to be copper oxide, which is formed
