Construction:

Conductor:7 strands class B compressed bare copper per ASTM B3 and B8 for 14, 12, and 10 AWG cables. Class K bare copper per ASTM B3 and B174 for 16 AWG (26 strands) and 18 AWG (16 strands) cables.
Insulation:Polyvinyl Chloride (PVC) with nylon layer. Type TFFN/TFN for 18 and 16 AWG cables. Type THHN or THWN for 14, 12, and 10 AWG cables. Types THHN or THWN are VW-1 rated.
Filler:Polypropylene filler on cables with 5 or less conductors
Binder:Polyester flat thread binder tape applied for cables with more than 5 conductors
Overall Jacket:Polyvinyl Chloride (PVC)

Applications and Features:

Southwire’s 600 Volt Type TC-ER control cables are suited for use in wet and dry areas, conduits, ducts, troughs, trays, 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 75°C in wet locations and 90°C in dry locations, 105°C for emergency overload, and 250°C for short circuit conditions. For uses in Class I, II, and III, Division 2 hazardous locations per NEC Article 501 and 502. Constructions with 3 or more conductors are listed for exposed runs (TC-ER) per NEC 336.10.
