The same is true for house wiring.

The real issue is voltage drop, particularly in a 12 volt system where you 
may not have a lot of spare volts to play with. I don't think #6 or #8, or their 
paralleled equivalents, are overkill in such applications.

We just installed #8 on a 240 line in the

#8 is the standard house-wiring size for 40 amps - #10 is only good for 30 
amps. And while the AC may not draw 40 A continuous, the initial starting surge 
may get up there. Don't want nuisance trips!

That's the way, regardless of short or long runs.
