UL Certificated Electric THHN Cable Wire
Applications:
THHN or THWN-2 conductors are primarily used in conduit and cable trays for services, feeders, and branch circuits in commercial or industrial applications as specified in the National Electrical Code. Voltage for all applications is 600 volts.
When used as Type THHN, the conductor is suitable for use in dry locations at temperatures not to exceed 90°C.
When used as type THWN, the conductor is suitable for use at temperatures not to exceed 90°C in dry locations, 75°C in wet locations, or 75°C when exposed to oil or coolant.
When used as type THWN-2, the 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. Conductor temperatures not to exceed 105°C in dry locations when rated AWM and used as an appliance wiring material. The voltage rating for all applications is 600 volts.
