THHN Wire Service Performance
Working Temperature: Rated drying temperature 90°C, nominal temperature 75°C wet, rated
THWN. Most THHN building wire features THHN/THWN double rating for
wet and dry applications.
When used as Type THHN, suitable for oil or cooling liquid
temperature not exceeding wet or dry places at 90°C or 75°C. When
used as MTW type, for conductors of 90°C in dry places, moist
places, or places exposed to oil or coolant not above 60°C.
Building Applications
THHN Wire represents high heat thermoplastic nylon coating.
Suitable for machine control circuit wiring or device applications.
Ideal for new configurations or rewiring at 600 volts applied, and
suitable for general use as defined by the National Electrical Code
(NEC).
