OK The switch I posted is upside down.
It is an interesting point about how it operates 'Rotationally' but I have never seen that applied to lever switches like this.
When I see the 'Rotationally' exception used it is usual with a round knob, very common on equipment constructed with IEC parts and not NEMA parts. Any switch rotates about an axis even a simple light switch. Once you add a lever IMO it must be down for off.
Anyway once we open the switch it becomes apparent it is upside down.
Someone took the time to turn over the labels on the out side of the box.
General-use and motor-circuit switches, circuit breakers, and molded case switches, where mounted in an enclosure as described in 404.3, shall clearly indicate whether they are in the open (off) or closed (on) position.
Where these switch or circuit breaker handles are operated vertically rather than rotationally or horizontally, the up position of the handle shall be the (on) position.
Exception: Vertically operated double-throw switches shall be permitted to be in the closed (on) position with the handle in either the up or down position.
