Opened the breaker panel and discovered this. The electrician was there and asked him about it. He said someone turned the power on when he was not ready. The arching power has destroyed the contacts for the rest of the bar and can not receive any other breakers. The top 50 amp breaker is burned on the side but functions as intended. The electrician has no intention of putting another breaker in the panel, but how about the next guy. My inclination is to call it as a safety hazard and have the load bar replaced. An hour job for him.
