FAQ
Q1: What does the THHN designation mean?
THHN stands for:
- T – Thermoplastic
- H – Heat Resistant
- H – High Heat Resistant
- N – Nylon Coated
This designation describes the cable's insulation and protective jacket construction.
Q2: Is THHN cable suitable for conduit installation?
Yes. THHN wire is specifically designed for installation inside conduits, raceways, ducts, and cable trays where mechanical protection is required.
Q3: Can THHN wire be exposed to sunlight?
Standard THHN cable is typically intended for protected installations. For outdoor applications, users should verify whether the product carries additional sunlight-resistant ratings.
Q4: What are the benefits of stranded conductors?
Stranded THHN wire offers:
- Improved flexibility
- Easier routing
- Better handling during installation
This makes it ideal for larger conductor sizes and complex conduit systems.
