![]() Outside Diameter: 3.05 mm / 0.120 inches.Allowed for Exposed Run (ER) and be used in accordance with NEC.May be used in Division 2 hazardous locations.May be used in NEC Class I and II systems.ANSI/NFPA 70 for Safe Electrical Design and Installation.UL 1277 (Resistant to flame, moisture, and sunlight). ![]() The jacket is color-coded in accordance with ICEA Method 4. Without being too bulky, it ensures that the cable can be used in harsh conditions. The cable is insulated with a thermoset plastic jacket (PVC) that is flame-retardant, sunlight-resistant, lead-free, strong, and stable. THHN THWN-2 conductors are constructed of annealed soft copper that follows ASTM B3 and ASTM B8 standards. Small Appliances: Think of household items like blenders, chargers, or desktop computers.ġ2 AWG THHN THWN-2 Construction: Conductor:.Lighting Circuits: Residential and commercial lighting circuits, both for ceiling lights and wall-mounted lights.Standard Outlets: Most commonly used in residential settings for standard wall outlets.Service Entrance: While specific SE cables exist for this purpose, THHN wires can also be used for service entrances when appropriately configured and protected. ![]() Feeders and Branch Circuits: In electrical distribution systems, THHN wires can serve as both feeders (which extend from service panels to subpanels or major appliances) and branch circuits (which extend from panels to outlets, lights, or individual appliances).Motor Connections: For connecting motors in both residential and commercial settings.Large Appliances: THHN wires can be used for connections inside large appliances like ovens, ranges, and HVAC units.Machine Tool Wire: In manufacturing and industrial environments, THHN is commonly used to wire machine tools and equipment.Control Systems: THHN can be used for wiring control circuits, including those for machinery, HVAC systems, and other building automation components.It's also commonly used in cable trays in industrial facilities. Conduit and Cable Trays: THHN is designed to be pulled through conduit, making it ideal for structured wiring systems in commercial and industrial settings.Building Wiring: This encompasses everything from lighting circuits to outlets in homes, commercial buildings, and industrial facilities.The building wire is rated 90 degrees Celsius in both wet and dry locations. Additionally, the cable is resistant to corrosion, excessive dryness, and the impact of chemicals. ![]() 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). Known for versatility and durability, it is the most common type of building cable. THHN stands for thermoplastic high heat-resistant nylon.

Applications requiring Type THHN or THWN-2, the conductor is appropriate for use in wet or dry locations at temperatures not to exceed 90☌ or not to exceed 75☌ in oil or coolants. Type THHN/THWN-2 building wire is intended for general purpose applications as defined by the National Electrical Code (NEC). Type THHN-THWN-2 is permitted for new construction or rewiring for 600-volt applications.
