The double marking THHN /THWN-2 indicates that the electrical wire is suitable for wet and dry conditions equally (The letter "W" means that it is water-safe). Additionally, the cable is resistant to corrosion, excessive dryness, and the impact of chemicals. The building wire is rated 90 degrees Celsius in both wet and dry locations. The electrical wire is rated at 600 V.
