Someone retro installed a load controller several years ago at this residence. After they slipped the amp reader coils around the service conductors, they forgot to re tighten the lugs.
I don't mean that they didn't tighten them enough, they didn't tighten them at all. I pulled them out without losening the lugs
The two wires were melted together at the top where they touched. It was coming close to a phase to phase short. When I pulled them apart, about 2" of bare wire was exposed.
The POCO guy noticed it when they were temporarily borrowing a neutral for the neighbors house. They left their split bolt and wire stub in there when they were done
I replaced the breaker and shortened up the wires a bit.
