Construction:

Conductor:Soild bare copper per ASTM B3, Class B compressed stranded copper per ASTM B3 and B8, or 19-strand combination unilay copper per ASTM B3 and B787
Insulation:Cross Linked Polyethylene (XLPE) Type RHH/RHW-2 or USE-2. Silicone-Free, High Heat, Moisture and Abrasion Resistant

Applications and Features:

Southwire's USE-2 600 Volts or RHH/RHW-2 1000 Volts power cables are suited for use in wet and dry areas, conduits, ducts, troughs, direct burial, aerial supported by a messenger, and where superior electrical properties are desired. These cables are capable of operating continuously at the conductor temperature not in excess of 90°C for normal operation in wet and dry locations, 130°C for emergency overload, and 250°C for short circuit conditions. Rated for 1000 lb/ft maximum sidewall pressure.

•Ampacities based upon 2023 NEC Table 310.16 and do not take into account the overcurrent protection limitations in NEC 240.4(D) of 15 Amps for 14 AWG CU, 20 Amps for 12 AWG CU, and 30 Amps for 10 AWG CU (independent of the conductor temperature rating and stranding if size is present in table). Also, see NEC sections 310.15 and 110.14(C) for additional requirements.
• Inductive Reactance is based on non-ferrous conduit with one diameter spacing center-to-center.
