THHN wire is a relatively stiff single conductor wire with solid or stranded copper conductors, PVC insulation, and a nylon jacket. It's a tough, abrasion-resistant wire suitable for use in conduits and raceways. THHN wire has a voltage rating of volts. You can use THHN wire for branch circuits in building and commercial wiring installations. The letters THHN have the following meaning:. Fixture wire is a single-conductor, flexible stranded copper wire with PVC insulation and a nylon jacket.

Considering its specific rating in Code, testing has shown that Copperweld CCA is the most energy-efficient conductor with the lowest voltage drop on the market. This offers energy savings to owners of homes and buildings, performance enhancements, and energy conservation for the good of society. Installed to NEC requirements and built to UL standards, Copperweld NM-B cable offers more electrical efficiency than its alternatives, pointing to lower monthly utility costs and smoother running equipment for homeowners. Its light weight and flexibility create opportunities for labor savings. Disincentivizing theft, it offers thieves only a small fraction of the scrap value of copper NM-B cable. Not for use with aluminum wire. Copperweld's Century family of grounding conductors have been installed in the harshest environments for over years. Copper is a valuable resource. CCA offers a fraction of the scrap value of copper building wire. When sized per Code, CCA delivers improved energy efficiency over alternatives.

Take care of general purpose wiring in branch circuits, control circuits, machine tools, and appliances with THHN, the most commonly used building wire. THHN wire is a relatively stiff single conductor wire with solid or stranded copper conductors, PVC insulation, and a nylon jacket. Run the grounding wire alongside the circuit wires. Contact us for help and technical advice on selecting the right building wire. These characteristics make THHN wire an excellent choice for controlling outdoor factors that would otherwise alter the performance of wire cable. Use a stud finder to locate the framing members and avoid running the wire through them. THHN thermoplastic high heat-resistant nylon wire is available in a wider range of gauges and is more heat resistant. Because THHN wire is UL-approved for permanent installation, it is commonly used in new construction and a variety of other projects where the wire will not need to be removed. You can use this wire for wiring luminaires to branch circuits and for internal wiring inside luminaires and other enclosed equipment where the wires aren't subject to movement, bending, or flexing. Ampacity tables that list the maximum ampacity for different gauges of wire at different wire lengths are available in The National Electric Code NEC. The letters TFFN stand for:. For twist-on wire connectors, simply screw onto the stripped wire. See The type of wire you should use for your industrial project depends on the specific application and where the wiring will be utilized.

For twist-on wire connectors, simply screw onto the stripped wire. Run a grounding wire from the main service panel to a grounding rod driven into the ground. The gauge of wire you should use for your industrial project depends on the amount of current amps that will be flowing through the wire and the length of the wire run. When using a push-in wire connector, inserted the wire into the then release it. THHN thermoplastic high heat-resistant nylon wire is available in a wider range of gauges and is more heat resistant.
