    Typically motor ratings would be for the entire motor, i.e. 6kW total power consumed (not 6kW per phase).

    The power rating should be for the unit on which the power rating is being given.

    As an aside: this raised an interesting discussion at the office on the consequences of a phase going down i.r.o. motors vs heaters.
    The trouble with opportunity is it normally comes dressed up as work.
