Amperage (Operating Current Maximum)
12 Volt 2% Wire Loss Chart
Maximum distance one-way in feet of various gauge two conductor copper wire from
power source to load for 2% voltage drop in a 12 volt system. You can go twice the
distance where a 4% loss is acceptable. A 4 to 5% loss is acceptable between batteries
and lighting circuits in most cases. Multiply distances by 2 for 24 volts and by 4 for 48
volts.
