My main question is, does the code allow me to run a smaller feed than the nameplate calls for? I dont see this anywhere in article 670. Any help is appreciated . Thank you
    This comment is based on your (purported) details notwithstanding other details you provided (eg) 192 FLA etc.
    The 33 HP name plate does make sense for existing #10 wiring

    I surmise this is a press trim guillotine type cutter?
    Most of this type machines are based on the GENEVA mechanism (i.e.) only one motor is running all the time while other motors that comprise the whole unit like indexing servos--only operate when called for. And when they do--they only operate momentarily.
    Typical machines found in book binding and CNC machines.

    Using the as-built info would resolve your dilemma.
