UL Industrial Cables THHN / THWN-2 / MTW

American Standard UL Industrial Cables THHN THWN 2 MTW

Application and Description Type THHN/THWN conductors are primarily used in conduit for services, feeder, and branch circuits in commercial or industrial applications as specified in the National Electrical Code®.
When used as type THHN, conductor is suitable for use in dry locations at temperatures not to exceed 90°C.
When used as type THWN, conductor is suitable for use at temperatures not to exceed 90°C, dry locations or 75°C wet locations or not to exceed 75°C when exposed to oil or coolant.
When used as type THWN-2, conductor is suitable for use in wet and dry locations at temperatures not to exceed 90°C or not to exceed 75°C when exposed to oil or coolant.
When used as type MTW, conductor is suitable for use in wet locations, or when exposed to oil or coolant at temperatures not to exceed 60°C, or dry locations at temperatures not to exceed 90°C (witd ampacity limited to tdat for 75°C conductors per NFPA 79).
Conductor temperatures not to exceed 105°C in dry locations when rated AWM and used as appliance wiring material. Voltage rating for all applications is 600 volts.
Cable Construction
Conductor Soft annealed bare copper, Class B
Insulation Tough, heat and moisture resistant Polyvinyl chloride (PVC) insulation over which a nylon (polyamide) jacket is applied.
