12 Volt Wiring Distance & Gauge Chart
12 Volt Wiring Distance and Gauge Chart
Just like 110 house current the type of wire must be matched to the voltage/amperage carried. This chart is configured for a 5% voltage loss for maximum one way travel. Simply find the amperage on the left...then look to the right in the same row for the distance traveled in feet (estimated) and then go up to find the gauge wire needed.
Example: 4 amps traveling 542 feet would need 1 guage wire.
