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. 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. The letters TFFN stand for:.

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.

Run the grounding wire alongside the circuit wires. For end users, this means greater flexibility for applications like push-button stations, fire alarm controls, and temperature control systems. Take care of general purpose wiring in branch circuits, control circuits, machine tools, and appliances with THHN, the most commonly used building wire. These characteristics make THHN wire an excellent choice for controlling outdoor factors that would otherwise alter the performance of wire cable. Cost Effectiveness THHN wire has grown in popularity since it is a cost effective alternative compared to other types of building wire. THHN wire has a voltage rating of volts. THHN is a thermoplastic, high-heat resistant, nylon coated wire. Licensed electricians or electrical engineers can provide guidance on determining the appropriate gauge wire for your specific application. TFFN is generally used for fixtures or branch circuit wiring. There are a variety of connector types, such as twist-on wire connectors or push-in wire connectors. Typically, the higher the amp rating, the larger the gauge wire will need to be. The NEC also permits versions with seven strands. 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. Run a grounding wire from the main service panel to a grounding rod driven into the ground. Run the wire through conduit or protective sleeves where necessary to protect it from damage.
