thanks for the reply. I guess it's okay amp range. I'll have to check those records you mentioned and see what they have on file. strange why the math for back calculating the horsepower doesn't come out quite right. given there's 746 watts per horsepower..a pump drawing 12 amps should be: 12amps x 240v = 2880watts / 746w = 3.85hp. I guess these pumps are operating at higher horsepower than their rating.. unless the 1.5hp is just a static rating,, as in pumping no water
