Introduction

Application Suitable for use as follows:

• Southwire Type RHH or RHW-2 or USE-2 conductors are used with conduit as specified in the National Electrical Code 1

• 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 or RHW-2 or USE-2 conductors is 600 volts

Standards&References:

Southwire 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), Federal Specification A-A-59544, and requirements of the National Electrical Code.

Construction:

• Southwire 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).

Specification:

• Conductors shall be UL-listed Type RHH or RHW-2 or USE-2, suitable for operation at 600 volts or less in wet or dry locations, including direct burial in the earth.

• Conductors shall be annealed copper, cross-linked polyethylene (XLP) insulated,

as manufactured by Southwire Company or approved equal.
