I stumbled across this picture on a BBS for home inspectors. Have any of you seen anything like this before? If so, please explain, I'm dying to understand. To make matters worst, isn't this a Federal Pacific panel?
Looks like a "split bus" panel. The bus is in 2 sections, with the lower half fed through the double pole breaker connected to the pigtails welded to the busbars.

it looks like that breaker feeding the split bus section is damaged.
