Can anyone tell me how far DC travels with efficiency. I am trying to rig a small water wheel within 100-150 feet of my country cabin. What size wire?
the resistance/1000 feet of #10 is
about 1 (0.001 ohms/ft), #20 is about (0.01 ohms/ft), #30 is about (0.1
ohms/ft), and #40 is about (1 ohm/ft). Voltage drop for most stuff should not exceed 10%
Why not just put an AC generator there? DC won't do you much good, anyway. If you want, I have some links about this subject that might be helpful, although you've probably read the same sites.
