UL 6703A OUTLINE

Description / Abstract: This Outline covers latching or locking type multi-pole PV connectors rated 1000 Vac or 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.

Multi-pole PV connectors may 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.

Multi-pole PV connectors are suitable for the termination of insulated, stranded copper type TC-ER, USE-2 or Photovoltaic Wire (PV Wire) rated 90°C, 105°C, 125°C, or 150°C dry; 90°C wet; 600, 1000, or 2000 V.

This standard does not apply to:

a) Single polarity dc connectors covered by the Outline in Investigation for Connectors for Use in Photovoltaic Systems, Subject 6703, and

b) PV wiring harnesses or cable assemblies consisting of connectors (single or multi-pole) assembled onto cables.
