The top 100amp breaker is the real main with the bottom one labeled "main" is the 100 amp breaker for the sub panel and the sub-sub panel.
I figured labeling both breakers as "main" was a no-no.

Kevin,
You may be looking at a “split bus” panel. ITE used to make those years ago, and I still see them every now and then in my area. They typically only had one main though, which cutoff all of the 110v circuits, with no more than 5 other 220v circuits. That allowed them to stay within “6 moves” rule without the expense of a 150 or 200 amp main (cheap, cheap, cheap). I’m just wondering if for some reason they might have wired this one with a second main for the 220’s.
