Use and Installation
This category covers multi-conductor, non-integrally jacketed, distributed generation (DG) cable. This cable is intended for use with specific distributed generation equipment/devices such as photovoltaic modules, inverters, solar trackers, etc. DG cable is suitable for use between cable trays and utilization equipment.
Structure
These cables are constructed with or without:
a) One bare or one or more insulated grounding conductor(s), and/or
b) One or more twisted pairs used for signal or communication,
all under an overall jacket.
Standard:
- ASTM-B, B-3
- UL Standard 83 for THHN/THWN-2
- UL Standard 3003
- RoHS environmental conductive requirement
Insulated Power Conductors
- Bare, annealed copper per ASTM B-3
- Compressed stranded per UL-83
Insulation
- Color-coded thermoplastic insulation/nylon jacketed per UL-83
Grounding Conductors
The cable may contain one or more grounding conductors. Each grounding conductor that is provided shall be of copper, aluminum, or copper-clad aluminum.
