On a service call at a mobile home, one leg of service wire heating up and bubbleing at main breaker,any thoughts.
Initial thought is as kwired's: insulation was stripped too short and got under the lug, resulting in a loose connection on the wire. Poor contact will cause overheating. Could just be a loose terminal lug. Could be corrosion too, whether by water or something like mouse urine (seen that twice now, once in a panel. Critter went phase-phase; rest in place. No missing KOs, no idea how it got in there).
Years ago I was sitting in my living room watching TV when I heard what sounded like a shotgun blast and the lights went out. A squirrel managed to get himself (or herself - it was impossible to tell) phase to phase across the terminals of the pole mounted transformer supplying the houses near me. This was forensically determined by a linesman I talked to at the scene; he found tiny bits of squirrel surrounding the point of the fault.
