1 Scope
1.1 This standard covers latching or locking type PV connectors either as a free connector (separate entity) or as a fixed connector (panel or bulkhead type) and rated 1000 V dc or less. These connectors are intended for use in wiring methods detailed in Part IV of Article 690 - Solar Photovoltaic Systems of the National Electrical Code, NFPA 70.
1.2 This standard is intended for single polarity PV connectors suitable for use on insulated, stranded copper type USE-2 or Photovoltaic Wire (PV Wire) rated 90C, 105C, 125C, or 150C dry; 90C wet; 600, 1000, or 2000 V.
1.3 This standard also covers latching or locking type multi-pole PV connectors rated 1000 Vac or dc or less. Multi-pole PV connectors consist of connectors, panel mounted connectors, distribution blocks and splitter connectors for the purpose of facilitating connections to and from inverters and like devices in a PV system.
1.4 This standard is also intended for multi-pole PV connectors suitable for use on insulated, stranded copper type TC-ER, USE-2 or Photovoltaic Wire (PV Wire) rated 90C, 105C, 125C, or 150C dry; 90C wet; 600, 1000, or 2000 V.
1.5 This standard covers PV connectors whose dimensions are not defined in any national or international technical standard. Connectors are identified and tested with compatible mating part (or parts if multiple exist) and are to be of the same brand, unless multiple product manufacturers are submitting under the same evaluation for the purpose of proving intermatability.
1.6 This standard does not apply to PV wiring harnesses or cable assemblies consisting of connectors (single pole or multi-pole) assembled on to cables, which are covered by the Outline of Investigation for Distributed Generation Wiring Harnesses, UL 9703. PV Wiring Harnesses may use PV connectors covered by this standard in their assembly. Harnesses have PV connectors factory assembled onto each end of the cable.
