White (N), Black (L), Green or Cu (Gnd), standard for 120v  circuits.  For 
240v use, the white wire should be marked red at the ends,  and the Gnd becomes 
the 240 and 120 N-Gnd. 









A standard 120v line with a black, white, and bare or green wire can ONLY  be 
made into a 220v line. NOT a 220/120v line.  The outer covering of a  Romex 
does not offer the insulation factor that is required to carry current in  a 
bare wire inside, only fault current that may occur during a fault.
 
  In some cases MC cable may be present which is armored cable with an  
insulated bond wire (green) which (by nature) can carry current, but is legally  
not allowed (by code) because of the color green.  Electrically this would  be 
OK, but still violates code.
