RHH / RHW USE-2 Solar Wire

RHH Wire, RHW WireType USE-2 Solar Wire—UL 44, NEMA WC 70

RHH, RHW, and USE-2 Solar Wire is designed for rugged performance in photovoltaic (PV) systems, offering long-lasting reliability in aerial, raceway, and direct burial applications. Made with cross-linked polyethylene (XLPE) insulation, this wire combines the flexibility of rubber with the chemical resistance and strength of polyethylene for a thermoset jacket that withstands extreme thermal, electrical, and environmental stress.

Commonly used in residential, commercial, and utility-scale solar installations, USE-2 cable is UL 44 rated and compliant with NEMA WC 70 standards. It’s built to perform in outdoor, exposed, or underground environments where traditional wiring may degrade or fail.

Whether you're wiring solar panels, inverters, or long conduit runs, our RHH/RHW-2/USE-2 cable is in stock in multiple gauge sizes and ready for immediate shipment. Ideal for green energy projects that demand efficiency, durability, and code compliance.
