cross-sections, and allow only alimited number of ampsto flow through them. To adequately figure out what size AWG wire you need, you require at least a wire gauge chart.
Calculate the maximum allowable wire ampacity for an insulated conductor as directed by the most recent NEC ampacity tables and charts.
Maximum distance in feet of various guage two conductor copper wire from power source to load for 2% voltage drop in a 12 volt system. Do not exceed the 2% drop for wire between PV modules and batteries. A 4 to 5% loss is acceptable between batteries and lighting circuits in most cases....
