DESCRIPTION
Copper RHH/RHW-2 and USE-2 wires are single conductor, cross-linked polyethylene insulated cables rated for 600V. Designed for general-purpose wiring in conduit, raceways, or direct burial applications. They offer excellent fire resistance, thermal endurance, and wet/dry usability, meeting UL44 and NEC Article 310 standards.
APPLICATION
Type RHH or RHW-2 or USE-2 conductors are used with conduit as specified in the National Electrical Code. When used as Type USE-2, conductors are suitable for use as underground service entrance conductors for direct burial at conductor temperatures not to exceed 90°C. When used as RHW-2 or USE-2, conductor temperatures shall not exceed 90°C in wet or dry locations. Voltage rating for RHW-2 or RHH or USE-2 conductors is 600 volts.
CONSTRUCTION
Type RHH or RHW-2 or USE-2 copper conductors are annealed (soft) copper. Insulation is an abrasion, moisture, heat, and sunlight resistant black crosslinked polyethylene (XLP). An optional CT rated product is available upon request for sizes 1/0 and larger.
