Virtually all of the power consumed by a microwave oven goes through the MOT
into the tube.  Maybe 10 watts is used for things like the timer, fan, etc.
The tube filament draws some power, but that goes through the MOT as well.
I would guess that the power limiting part of an MOT is the primary winding,
not the secondary.
