This was a house panel on the back side of a strip mall. I was called out to trouble shoot and repair parking lot lights that were not working. After researching, I found the panel. First the total enclosure had been hit numerous times by trucks. I could barely access it with out pulling it from the wall. The problem, it turns out, was a loose main lug which eventually destroyed the conductor. But, as I looked at all the controls, nothing was right...

The conductors coming from the meter terminated at a 150 amp main breaker. (Barely held on by short screws) >From there the went to a old contactor which was operated by a time clock. The time clock in turn was powered by the load side of the main.(no inline fuse) back to the feeders. From the contactor they terminated to a federal pacific main lug panel. So the whole panel was being shut down during the day. The last 2 pics is what I did to repair it...
