Full load for a treadmill would be the treadmill operating at the fastest speed available, with a person about 250 pounds, while also operating the incline function. As you can surmise, this would probably never happen, so there is plenty of safety factor included in the rated amp load or the unit.

With sine wave chopping controllers for speed as most of the newer things are it is no telling what a tru RMS value may be. Of course the listed values I was giving was at full load. What would be full load for a treadmill. Somewhere there should be info in the literature or on a name plate giving a wattage or amperage for the entire unit, which in your case is what is important.. Two and one fourth horse power is a non standard horsepower, which I have saw similar on imported equipment. Probably because it is designed for 50 cycle the horsepower rating changes for our 60 cycle.

I don't recall the formula for calculating the electrical current usage but I know that there are several on here who do know it off the top. It is on a fairly lightly used circuit but that of course depends on the time of day as outside lights ETC are also on that line. I can change things around here and need to know if I should or not.
