I think the trick here is that they aren't given the flc for the test, only the motor power rating (it's not a real motor IIRC, just a terminal box). But on the basis of post #6 the power quoted is not given as normal on a motor (output power) but the electrical input power. Or whoever wrote that suspect-looking page was even more barking.
