RW> No, the wire is the same as used on 110v. I ran 100 feet of 3/12 to drop   
   RW> 220v at my milling machine. It has a phase converter on it that changes   
   RW> that 220v single phase to 3 phase. The phase converter manufacturer   
   RW> confirmed to me that there would be plenty of voltage at the end of that   
   RW> 100 feet. He was right. I have 219 to 232 volts.   
      
   Maybe I am thinking about a higher amp line.  I think my old hot tub needed to   
   be on either a 30 or 50 amp breaker.  I can't remember.  The issue was, the 50   
   amp wire is more difficult to work with due to the gauge being thicker.   
      
   I could tap into another circuit to the garage without too much trouble, but   
   believe they are all 30 amp 110v.  The dryer is on a higher one and 220v, but   
   I wouldn't want to share that with the compressor.     
      
   I also have a fridge in the garage, so I will already be pushing that one   
   feed.    
   If it is possible to tap into the existing 110v outlet that the fridge is on   
   in the garage and make another outlet that is 220v, that would work.  I didn't   
   think something like that was possible.
