Is THW wire waterproof?
What Is THWN Wire? THWN is similar to THHN, except it is water-resistant, adding the “W” into the acronym. THWN is rated for up to 167°F or 75°C in wet environments, but its successor, THWN-2, is rated for 90°C in both wet and dry environments.
Is Thhn and thw the same?
The thermoplastic PVC is flame-retardent and the nylon jacketing is resistant to gasoline and oil. THHN stands for Thermoplastic High Heat-resistant Nylon-coated. THWN wire is the same, but the "W" stands for water-resistant. ... However, most of these wires, so you can use THHN and THWN interchangeably.
