Calculate the maximum allowable wire ampacity for an insulated conductor as directed by the most recent NEC ampacity tables and charts.
On top of that, we also have toaccount for the 80% NEC (National Electrical Code) rule. This rule states that no 6 AWG wire can be loaded over 80% of its rated ampacity. We will explain what this means later on. Here’s a quick take: ...
Voltage Drop & Max Ampacity ChartsMaximum 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 ...
