Applications and Features:

Southwire SDN (Small Diameter Neoprene) flexible control tray cables 600 Volt are suited for use in industrial power or control circuits where small diameter, flame retardant cables are desired. These cables are suitable for use in wet and dry areas, conduits, ducts, troughs, trays, direct burial and where superior electrical properties are desired. Southwire SDN cables listed as THHN/THWN are capable of operating continuously at the conductor temperature not in excess of 75°C in wet locations and 90°C in dry locations, 105°C for emergency overload, and 150°C for short circuit conditions. For uses in Class I, II, Division 2 hazardous locations per NEC Article 501 and 502. Southwire SDN flexible control cable is CSA listed Type TC and as Control and Instrumentation Cable Type (CIC)

    † 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.
    † Ampacities have been adjusted for more than Three Current-Carrying Conductors.
    * Inductive impedance is based on non-ferrous conduit with one diameter spacing.
