Copper Clad Aluminum (CCA) wires do not follow the American Wire Gauge standard (AWG). AWG is developed for electrical resistance classification of Oxygen Free Copper (OFC) wires. High current application specifying AWG standard assumes the wire is OFC. Same conductor area CCA has higher resistance than OFC making AWG classification invalid. CCA wires are developed for low current applications (e. g. passing signals). As a rule of thumb, reduce CCA gauge size by 2 to achieve similar electrical
