THHN wire

THHN wire is a type of electrical wire commonly used in building wiring and conduit systems. The letters stand for Thermoplastic High Heat-resistant Nylon-coated, meaning it’s insulated with a durable, heat-resistant plastic and coated in nylon for extra protection. It’s designed to handle different voltage levels and temperatures, making it suitable for indoor and outdoor use, including residential, commercial, and industrial applications. The wire typically comes in copper or aluminum and is rated for safety and reliability. Overall, THHN wire is a versatile, safe choice for conducting electricity in various wiring projects.
