Underground Service Entrance Cable. 600 Volt. Copper Conductors. Cross-Linked Polyethylene
(XLP) Insulation. High-Heat, Moisture, and Sunlight Resistant. Sizes 6 Through 4/0 AWG Also
Rated SIS.
Southwire® Type RHH or RHW-2 or USE-2 conductors are used with conduit as
specified in the 2011 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 or
RHW-2 or USE-2 conductors is 600 volts.
Southwire® Type RHH or RHW-2 or USE-2 comply with the following:
• ASTM - B3, B8 (7, 19, 37, 61 Strands), B787 (19 Wire Combination Unilay Strand)
• UL Standard 44 for RHH or RHW-2
• UL Standard 854 for USE-2
• Federal Specification A-A-59544
• National Electrical Code, NFPA 70 - 2011 Edition
• NEMA WC 70 Construction Requirements
• RoHS/REACH Compliant
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 crosslinked polyethylene (XLP). An optional CT rated product is available upon request for
sizes 1/0 and larger.
