    RW>> That is true, but previously you based your figures on horsepower,

    TW> In the Electrical Trade as far as power consumption goes Horsepower

   Meanwhile, the utility company won't bill you for horsepower used. That's   
   the whole point of billing in Kilowatt Hours.   
      
    RW>> TW> IT is the Amps tiems the Voltage so the 220 volt motor drawing

   I did't imply that. I said that you can save money by running 220v vs   
   110v, but I didn't say how.
