1 Answer

Answer :

Stranded wire gauges should be measured by calculating the equivalent cross sectional copper area. First, measure the bare diameter of a single strand and locate the circular mils value in the row that matches your measurement. Second, multiply the circular mils by the number of strands in the cable.
