Wrenches,
This may have been discussed previously but would appreciate input. I'm 
using a long run of wire 2/0 ga. copper would put me right on the line 
for 5% line loss (wind turbine @48v approx. 52 amps max. output, 2.5kw) 
. 4/0 aluminum would be about 6.3% voltage drop according to my 
calculations. The aluminum is a much bigger piece of wire but less than 
half the price. Any comments on working with one vs. the other?
