Product Overview
This UL-listed Distributed Generation (DG) Cable delivers robust performance for solar and renewable energy systems. Engineered for exposed runs (ER) between cable trays and utilization equipment per NEC Article 691 and UL 3003, it interconnects PV modules, inverters, solar trackers, and energy storage units. Rated 600V, 90°C dry / 75°C wet with sunlight/oil resistance, it streamlines installations while meeting stringent safety and environmental standards.
Key Features & Benefits
-
Dual-Rated Insulation: THHN/THWN-2 construction eliminates wire changes between dry/wet locations.
-
Integrated Grounding: Optional bare/insulated grounding conductors (copper, aluminum, or CCA) sized per NEC Table 250.122.
-
Signal Integration: Twisted-pair data cores (20–22 AWG) reduce BOM costs and tray fill.
-
Certified Safety: Compliant with UL 3003, UL 83, ASTM B-3 & RoHS 2011/65/EU.
-
Environmental Durability: UV-resistant (720h Xenon-arc per UL 2556) and oil-resistant (IRM 902 tested).
