Output cables and Interconnect cables are used between PV arrays, junction boxes, and/or inverters. Use them to extend module output cables or cut anywhere along the wire to obtain the needed length of male and female cable to run from the ends of a module string to a combiner box or to an inverter.
All cables are manufactured with #10awg PV Wire, which UL 4703 rated and double jacketed/insulated. PV Wire is now needed for ungrounded arrays in conjunction with transformerless inverters. This type of wire is required to meet the 2008 NEC if you are using a transformerless inverter.
