RHH/RHW-2/USE-2 COPPER CONDUCTOR

Introduction

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.
Standards: ASTM-B3, B8 UL44, UL854
