RW> RW>> The difference of course is in how much it costs to run the   
   RW> RW>> compressor. In an industrial environment, running anything on 110v   
   RW> RW>> costs twice as much to run as the same piece of equipment on 220v.   
   RW> RW>> Even less if it's 220v 3 phase.   
      
   RW> TW> That statement got lost in this old Brain. cost of rinning an   
   RW> TW> electric motor for an air compressor is a function of the horsepower   
   RW> TW> of the motor.   
      
   RW>Roy> No, it's more than that. When you use 110v at 10amps to run an   
   RW>Roy> electric motor, it will cost you twice as much as a 220v motor,   
   RW>Roy> because the 220v motor will use half the amps.   
      
   RW>Right, but the wattage used is the same, and it's watt/hours you're billed f   
   RW>iirc.   
   RW>RW> Power used in Watts is equal to Amperage times Voltage.   
      
   GOOD Recall   
      
   Roy can get me easily about Automobiles but Electrical/Electronics in MY   
   field and he is missing something in this discussion.
