FAQs
Q: Can this wire be used outdoors or in wet locations?
A: Yes! The THWN rating allows use in wet environments when installed in conduit.
Q: What’s the difference between THHN and T90?
A: T90 meets Canadian standards (CSA) with a 90°C dry rating, while THHN is UL-listed for U.S. markets.
Q: Is nylon coating necessary?
A: Yes. The nylon layer protects against abrasion and moisture, extending wire lifespan.
