Applications:
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, conductor is suitable for use as underground service entrance cable for direct burial at conductor temperatures not to exceed 90° C. When used as RHH, conductor temperatures shall not exceed 90°C in dry locations. When used as RHW-2 or USE-2, conductor temperatures shall not exceed 90°C in wet or dry locations. Voltage rating for RHH o RHW-2 or USE-2 conductors is 600 volts.

Specifications:
Type RHH or RHW-2 or USE-2 meets or exceeds UL Standard 44 (for RHH or RHW-2), UL Standard 854 (for
USE-2), ASTM B3 Soft or Annealed Copper Wire, ASTM B8 Concentric Lay Stranded Copper Conductors or ASTM 787 19
Wire Combination Unilay-Stranded Copper Conductors, Federal Specification A-A-59544, and requirements of the National Electrical Code. Sunlight Resistant. Colors available. Type RHH or RHW-2 or USE-2 meets and exceeds all construction requirements of ICEA S-95- 658 (NEMA WC 70) - Nonshielded 0 - 2 kV Cables, with testing frequencies based on UL requirements.

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 cross-linked polyethylene (XLP).
