Sorry the pic is sideways. I can not figure out why that happened. Anyway I am stumped. I cant figure out why there are 2 70 amp breakers connected to each other. I have seen my share of split bus panels but this does not look like anything I have ever seen before. The bus bars look like they are one piece. From what I can see the SEC feeds both sides of the panel. Why the 70 amp double pole breakers?
