I didn't mean to start an arguement gentleman. Did I mention the line was 400 feet in length? I think I will just install a transformer at the beginning of the line and install low voltage. I can still use the existing #10 if I can just figure out how to get those small little low voltage clips to attach to the #10 sheathed electrical cable. any suggestions? By the way Dodgeman, I have only (7) 50 watt mini floods and (2) 15 watt light on the line. I guess its all in the lenth of the run. Maybe I can re-run the first 100 feet in #8 to give me the last 40 feet of amps that I need to carry.
