Industry-standard locking-style MC4 PV cable 15-foot extensions from Colorado Solar. This extension is perfect either to extend one wire 15 feet to another MC4 connection, or cut in half to extend both positive and negative wires 7.5 feet to normal bare wire connections (circuit breaker or bus bar in combiner box for example). UL listed 10 AWG size PV wire. This wire is PV rated, but does not have an extra thick insulation or extra fine stranded wire, so this wire will work with standard cable grips and connector contact sleeves.
