[Amps] AC wiring

I just obtained a 2nd Alpha and thought about using the same 10AWG run for
both.  Then the fog in my brain cleared and I decided to pull another
circuit for it.

10AWG is probably the minimum I would use for a new electrical installation.

A few years ago,  I ran 4-pole 240VAC with #10 over a 60-foot run for use 
with my Alpha amps.   At 1500W, the line voltage sag is okay but not great. 
If I had to do it over again, I would probably double the wire size, then
meditate real hard before wrestling with the wire pull.  But I think the
results would be worth the extra pain.
