    Nothing required the manufacturer to list a maximum breaker size, so why list it? It's just going to be the same thing the Code already tells you.

    But there is a difference,

    422.11(e) indicates "Not to exceed 150%".
    422.13 refers to 422.10 which indicates "Shall not be less than 125%".
