14 gauge flexible copper clad aluminum low voltage primary wire 6 color set, 100ft roll (600 ft total) for 12 volt automotive trailer harness car audio video wiring gs power <b> copper clad aluminum (cca) wires do not follow the american wire gauge standard (awg). </b> <br> this wire set uses the same 14 gauge standard as best connections (number of strands and strand diameter are the same) <br> awg is developed for electrical resistance classification of oxygen free copper (ofc) wires. high current application specifying awg standard assumes the wire is ofc. <br> same conductor area cca has higher resistance than ofc making awg classification invalid. cca wires are developed for low current applications (e. g. signal processing). as a rule of thumb, reduce cca gauge size by 2 to achieve similar electrical resistance as ofc wires. <br> for selection of ofc wires using awg standards, <b> visit www.amazon.com/gspower </b>
