Industrial Cables |
THHN/THWN, 600V, Type TC control Cable
Application
Type TC Control Cable is for use in industrial power or control circuits where small diameter, flame retardant cables are desired. Primary installations include cable trays, raceways, and outdoor locations where supported by a messenger wire. Type TC is also listed for direct burial and for use in Class 1, Division 2 hazardous locations and Class 1 control circuits. Constructions with 3 or more conductors are listed for exposed runs (TC-ER) per NEC 336.10. Conductors may be used at temperatures not to exceed 75°C in wet locations or 90°C in dry locations. 130°C for emergency overload ratings, and 250°C for short circuit ratings. Not recommended in D.C. operation in wet locations.
Compliances
- NFPA 70 (NEC)
- UL 1581 - Electrical Wires, Cables and Flexible Cords
- ICEA S-58-679 - Control Cable Conductor Identification Method 1, Table 2
- UL 1685 - UL Flame Exposure Test (70,000 Btu/hr)
Construction
| Conductor |
Soft annealed bare copper, Class B stranding per ASTM B8 |
| Insulation |
Polyvinyl chloride (PVC) insulation over with a nylon (polyamide) jacket applied |
