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).

Electric Wire Model Selection Guide
- Lighting: Generally uses 1.5 square single core hard wire (BV1.5), divided into live wire and neutral wire by color
- Sockets: Generally use 2.5 square single-core hard wires (BV2.5), with air conditioners above 3 HP using 4 square (BV4) or larger single-core wires
- Home Bus: Generally uses 6 square meters (BV6) or larger single-core wire
- Consultation: Please consult online customer service for specific configuration and quantity requirements
