[Wire] Photovoltaic Wire

See General Information for Wire

GENERAL

This category covers single-conductor, insulated and integrally or nonintegrally jacketed, sunlight-resistant photovoltaic (PV) wire intended for interconnection wiring of grounded and ungrounded PV power systems as described in Section 690.31(A) and other applicable parts of ANSI/NFPA 70, "National Electrical Code."

PV wire is rated 600, 1000 or 2000 V, and is suitable for ac and dc systems. This wire is rated 90, 105, 125 or 150°C dry and 90°C wet. PV wire employs 12 AWG - 2000 kcmil stranded aluminum or copper-clad aluminum, or 18 AWG - 2000 kcmil stranded copper conductors.

PRODUCT MARKINGS

PV wire is marked on the outer surface of the insulation with the manufacturer's identification, the words "Photovoltaic Wire" (or "PV Wire"), voltage rating, conductor size, dry and wet temperature ratings, the words "Sunlight Resistant" (or "SUN RES"), nominal outside diameter, and date code (if not marked on the tag). PV wire having aluminum conductors is marked "AL," with or without "ACM." PV wire having copper-clad conductors is marked "ALUMINUM (COPPER-CLAD)" (or "AL (CU-CLAD)") or "COPPER-CLAD ALUMINUM" (or "CU-CLAD AL"). PV wire complying with the VW-1 flame test is marked "VW-1." PV wire complying with a cold impact test is marked "-40 C." PV wire may also optionally be marked "Direct Burial" (or "Dir Bur"), or "for direct burial" if it complies with crush and impact tests.

Each package of PV wire is tagged or marked with the manufacturer's identification, the words "Photovoltaic Wire" (or "PV Wire"), voltage rating, conductor size, dry and wet temperature ratings, "Sunlight Resistant" (or "SUN RES"), and date code (if not marked on the wire). If the PV wire contains aluminum conductors the tag is also marked "Aluminum" (or "AL"), or the markings are overprinted with the words "aluminum conductors," with the additional marking "ACM" being optional. PV wire having copper-clad conductors has a tag marking of "ALUMINUM (COPPER-CLAD)" (or "AL (CU-CLAD)") or "COPPER-CLAD ALUMINUM" (or "CU-CLAD AL") and the following statements:

1. "Copper-clad aluminum shall be used only with equipment marked to indicate that it is for use with aluminum conductors. Terminate copper-clad aluminum with pressure wire connectors marked AL-CU or CC-CU."

2. "Where physical contact between any combination of copper-clad aluminum, copper, and aluminum of a type marked for such intermixed use and the connection shall be limited to dry locations only."

PV wire complying with the VW-1 flame test is marked "VW-1" on the tag. PV wire complying with a cold impact test is marked "-40 C" on the tag. PV wire may also optionally be marked "Direct Burial" (or "Dir Bur"), or "for direct burial" if it complies with crush and impact tests.
