I recently touched a wire on fuse box and now I have no power. Fuses are all good breaker good. Can the wire be dead? Is that a thing?
Wires don't go bad, but wire connections can become loose. They can also develop a burnish or tarnish on the surface which can result in a poor electrical connection, lading to an increase in electeical resistance, which in turn can create a hot spot and melt nearby wire insulation, maybe even start a fire.
