One fact to know is that many machine motors may not ever require the full amount of current rated on the motor (i.e. full load amps). This depends on what kind of machine it is and what you are trying to do with it. For example, a 5HP table saw that is rated at about 16 full load amps will only require about 1300 watts when just spinning the blade. A 16 amp full load would be about 3750 watts. But if you are pushing through some 2" dense hardwood, the current draw will definitely go up. Various machines machine pull different "actual current" depending on what kind of machine it is. One machine that will definitely pull "full load amps" is your dust collector when all blastgates are open.
