Argh.  Let's try that table again.

It's a linear relationship, so I can just drop this little table in here
for gauge vs voltage drop at ten amps and ten feet.  Y'all can multiply and
divide from there (my numbers are for 150F, figure a few per cent less drop
at 77F).  The only factors are the current and the resistance, so for a
given current you can just add up the drops from various segments of the
line.  Don't forget there are losses at the connectors too.

E (drop in volts)       I (amps)        Ft      Ga      ohm/k-ft
