PV-Cables 150' Huber & Suhner Radox PV Output Cable, 55.0150 Radox solar connectors consist of a housing and contact element. Lamella contacts made of high quality copper beryllium are responsible for the high current carrying capacity of the connectors. Without a lamella contact these advantages cannot be achieved. The lamella contact as a flexible element provides mechanical compensation between socket and pin. The lamella produces a large contact surface between the elements and guarantees a low, constant transition resistance. Made with PV-Wire that has an extra layer of insulation for use on ungrounded arrays in conjunction with transformerless inverters. All cables are manufactured with #10awg PV Wire, which is 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.
