This Southwire 500-foot THHN (Thermoplastic High Heat-Resistant Nylon-Coated) wire, Model 22974057, is a single-conductor 10 AWG stranded copper building wire designed primarily for installation inside conduit or cable trays where it protects and distributes electrical power. THHN is a widely accepted trade designation for building wire that meets stringent electrical code standards, offering durability and versatility for branch circuits, feeder runs, and control wiring.
The stranded construction of the copper conductor increases flexibility compared to solid wire, making it easier to pull through conduit and around bends during installation. Thermoplastic PVC insulation and a nylon jacket provide resistance to heat, moisture, gasoline, oil, and abrasion, enhancing service life in demanding environments.
Rated for 600 V and suitable for use in dry and, in some applications, wet locations when properly terminated, this THHN cable is a reliable choice for commercial and residential electrical systems requiring dependable conductor performance and code-compliant wiring solutions.
