Howdy,

I need to run some 220v single phase outlets in the garage.  I'm using 
range plugs and 50A breakers.

Looks like I should be using 6/2 wire w/ground for this right?  I.e. two 6 
guage shielded conductors, w/ a single (smaller, solid) bare ground wire?

As I recall, 220v single phase has all the current going through the two 
shielded conductors (which are tied to the two 110v legs in the box, one 
on one, one on the other), and the ground doesn't come into play, correct?

I'm asking because the 6/2 wire I just bought seems to have a much smaller 
bare ground wire, which I wouldn't think would cut it if there was any 
current normally going through there.

Thanks!

Mark
