Adventures in electricity......

Here is the main breaker box at the house.  Installed in 1977 and lived a good life. 

Here are the original guts.  Crowded and scary looking!

Here is where the 200 amp component was "arcing" and buzzing. 

 

This shows where the unit had been heating up and burning.... 

The silver part with the two circular burn marks is the "bust bar."  Like my new electrician terms?!
Apparently things were not good and the whole thing needed to be replaced.
