RW> Amps = Power in Watts divided by Voltage.   
   RW>    
   RW> 5000 Watts of Power / 220v = 22.7 Amps.   
   RW> 5000 Watts of Power / 110v = 45.5 Amps.   
   RW>    
   RW> Nope. As indicated above, 220v is more efficient than 110v...by 3 Amps.   
   RW>    
   RW> And at the end of the day, you're not charged by the voltage used, but by   
   RW> the Power you have consumed. If there's 220v available, why use 110v?   
   RW>    
   RW> As indicated above, equal power usage leads to doubled amperage use on a   
   RW> 110v motor thus leading to a higher bill at the end of the month.   
   RW>    
   RW> Your bill is determined by how much wattage you use, not by how much   
   RW> horsepower your motor is rated.   
      
   Thanks for the detailed information on 110v/220v!  An electrician friend of   
   mine had told me the basics before, but not in detail with the actual   
   calculations.     
      
   Why doesn't everyone run everything at 220v?  I know the wire itself is much   
   more expensive and bulky.  Seems it would save money on everything if they   
   were made for 220v.     
      
   My guess is what 220v transformers (power bricks) would be much more expensive   
   and the products would cost more.   
      
   I should have run another 110v and one 220v to the garage before the basement   
   was finished.  It would not have been that difficult at the time.
