1 conductor per phase utilizing a #14 Copper conductor will limit the
voltage drop to 0.37% or less when supplying 0.41 amps (about 50W at 120V)
for 200 feet on a 120 volt system.

That's what I like about you, John -- a very practical guy! How would 
you like to coordinate our next Field Day?

For those not capable of doing the arithmetic, the voltage drop in 
several hundred feet of extension cord for a 50W soldering iron is 
pretty small.
