Withing the last 2 months, my main 150 amp service breaker has started tripping when the Dryer and AC run at the same time. Non of the branch circuits are tripping. I borrowed the thermal imager from the plant and noticed that the left side is running hot at about 160 degf but the right side runs at about 115 degf. My initial thought was improper load balancing had ruined the main over the last 15 years but the guy at the local electrical supply shop said that main breaker rarely go bad. It does not appear to be a load balancing issue. Any ideas? It is a Cutler Hammer 150 volt panel.
