WhisperFlo WF-24 rated at 1hp, then 746 watts, then would draw .746 kW
Can measure draw by counting beats / seconds on the meter and calculate with the formula
3600 * beats / seconds * kh * multiplier / 1000
where kh is a number from the meter, in this case .6
and multiplier is also a number from the meter, in this case 80
Measured draw is 2.34kW with pump on and 0.35 with pump off
Would seem pump draws 1.99kW
Why would measured draw be so much higher than predicted?
