I have kind of a strange question. Today I was working on a lighting timer and shorted it. The 20A breaker flipped and I figured end of story; however half the building lost power, so I called in the power company. When they showed up, the guy opened the service disconnect (Fusible, 240V, 1000A) and the bus bars that connect the utility to our side were almost all the way out. Me shorting the power was the straw that broke the camels back. 2 phases were completely disconnected and one barely hanging on. The handle was in the fully on position. He asked me if anyone had messed with it and I said no. He ended up taking a dead blow and hammering the bars back in. Anyways, my dad and I were kind of curious if maybe after 26 years, the bars just vibrated out, or if it was kids who were messing with the switch (they broke our timer box, so they could turn off the lights to the building). I wouldn't think it was vibration, because it took some effort to put the bars back in fully, so there is plenty of tension. Anyone ever seen some thing like this?
