To approximate the actual load, run the motor uncoupled and record the no-load current Do not take shortcuts here! If you run the motor coupled but “unloaded,” the value obtained will be wrong Driving an unloaded pump, conveyor, or fan still takes some torque, so your estimation of hp load won’t be correct
