Damaged insulation

This was where I used to work. I stripped the cable sheathing and noticed the neutral insulation has been previously damaged, oops! I guess it was the last couple of foot from a reel xD.

Another thing, see the keyless socket underneath? Well it comes from a worklight a drywaller from the place asked me to repair. The cable partly hides it, but since it's cheapo, the aluminium screw broke off of one rivet inside. That rivet also connects the screw to the neutral terminals, so the lamp started arcing and flickering. Then it simply went out, but wiggling the lamp produced blue sparks inside the socket and lit the lamp a little xD
