    Makes sense. So in order to change the NEC, I'd need to change 99, right?

    Probably no need to do anything with the NEC. Just a requirement that in 99 that those facilities have AC systems supplied by a back up power system.

    This type of requirement, if proposed should be in the building code, not the NEC
