A months back the a breaker on my consumer unit tripped. I flipped the breaker back and approx 20mins later I heard a pop sound from a socket. I removed the faceplate and could see the earth wire was blackened and a fair amount of blue dust around the earth wire at the point where the white insulation was cut. The red and black wires were perfect. The entire wire was blackened when I removed the earth sleeve.
I have about 8 inches of slack wire and when I stripped the earth back six inches its still blackened with small amounts of blue dust. I think this is copper sulfide.
I think the wire runs under screeded floor but in a cavity.
Can I clean the wire with sand paper or will it need replacing?
Any advice would be helpful
