I thought I could go right to a chart for the capacity of amps on wire size. I cannot find the chart I used before.  I have a 24 v system and need to go either 420 ft or 375 ft from the solar panels to the control room. 5 panels 240 w 24v. ea panel is fused at 10 amps. 2 wires from the combiner box to controler. Could some one direct me to a chart. 13

I made a cable calculator a while back where one can calculate needed size for a given length/load/max-loss, or loss in a given length/load. All in metric, though... ;)

A simple program that need little: http://mwlmf.net/prog/CableCalc11US.zip
