THHN/THWN-2 is a versatile building wire widely used in residential, commercial, and industrial electrical systems. Its key features include heat resistance, moisture/water resistance, and oil resistance, making it suitable for various power and control circuit applications.
1. Electrical Wiring (NEC Compliant)
✔ Residential – Lighting, outlets, and panel feeders
✔ Commercial – Branch circuits in offices, malls, hotels
✔ Industrial – Machine power supply & control wiring
2. Conduit & Cable Tray Installations
✔ Ideal for metal/PVC conduits (nylon jacket provides smooth pulling)
✔ Suitable for dry or wet locations (THWN-2 rated for water resistance)
3. Equipment & Machinery Wiring
✔ CNC machines, HVAC systems
✔ Control panels, relay circuits
✔ Pumps and compressors
4. Special Environments
✔ Oil & chemical-resistant (refineries, plants)
✔ Outdoor use (with waterproof fittings)
Conductor: Bare copper or aluminum
Insulation: PVC
Outer jacket: Nylon (for THHN)
1.Q: What's the difference between THHN and THWN-2?
A: THHN is rated for dry locations (90°C) while THWN-2 can be used in both wet and dry locations (90°C wet/75°C dry). THWN-2 has additional water resistance properties.
2.Q: Can THHN/THWN-2 cable be used outdoors?
A: Yes, but only the THWN-2 rated version can be used outdoors or in wet locations when properly installed in conduit. THHN alone is not suitable for outdoor use.
3.Q: What types of installations is this wire suitable for?
A: It's ideal for conduit and cable tray installations in commercial/industrial buildings, control panels, machine wiring, and general power distribution when installed according to NEC guidelines.
