THHN stands for Thermoplastic High Heat Resistant Nylon, so just from the name we are able to tell that the wire is made of thermoplastic material, can withstand high temperatures, and features a nylon jacket.
THHN is UL listed with a rated 90 degrees Celsius in dry locations or 75 degrees Celsius in wet applications with a THWN rating. The vast majority of THHN building wire carries a dual rating on the cable marked THHN / THWN for both the wet and dry temperature rating. THHN building wire may also be used for wiring of machine tools, control circuits or on certain appliances.
