6 AWG 19-Stranded THHN Black Copper Building Wire (100FT)
Stock Wire offers a 6 AWG 19-stranded THHN black copper building wire with a 100-foot length. The product uses annealed copper conductors and a high-heat, moisture-resistant PVC insulation. The nylon jacket provides abrasion and chemical resistance, making it suitable for wet or dry locations. This option is designed for reliable power distribution to outlets, switches, and other loads in residential or commercial settings. The 19-strand construction enhances flexibility during installation while maintaining strong electrical performance.
500 Foot Spool 6 AWG 19-Stranded THHN-THWN-2 Copper Building Wire
Arizona Electrical Solutions provides a long 500-foot spool of 6 AWG copper building wire with a THHN-THWN-2 rating. The 19-stranded copper conductor delivers good flexibility and conductivity for complex runs, while the continuous length reduces waste and splicing. This versatility supports both dry and wet location installations and is well-suited for larger residential or commercial projects where long runs are common, such as feeders or subpanels.
6 AWG THHN Stranded Bare Copper Wire 100FT Green Grounding
XRDS -RF offers 6 AWG stranded bare copper wire with a 100-foot run, emphasizing pure copper for robust conductivity and reliable performance. The THHN insulation provides heat resistance and protection from moisture, while the bare copper conductor is ideal for grounding, panel wiring, and control systems in various environments. This option is particularly suitable where bare copper grounding pathways are required in conjunction with insulated conductors.
THHN Wire 6 Gauge 100 FT Stranded Copper Wire (Kimbluth)
Kimbluth markets a 6 AWG THHN stranded copper wire with a nylon jacket designed to withstand higher temperatures and provide resistance to heat-related jacket migration. The 100-foot length is suitable for mid-scale installations, and the combination of copper conductors with a nylon jacket supports use in both dry and wet environments when installed in conduit. The product emphasizes safer, lighter wiring with durable insulation properties for residential or industrial projects.
6 AWG 19-Stranded THHN Green Copper Building Wire (50Ft Cut)
Stock Wire provides a 50-foot cut of green copper THHN 6 AWG, featuring annealed copper conductors and a PVC insulation jacket with a nylon overcoat. The green variant is commonly used in grounding or as part of color-coded installations, offering the same moisture and abrasion resistance as the black version. This shorter length is convenient for smaller projects or specific circuit requirements where color differentiation is helpful.
XRDS-RF THHN Wire 25FT, 6AWG Stranded Copper
XRDS-RF offers a 25-foot segment of 6 AWG stranded copper THHN electrical wire with a black nylon-coated thermoplastic insulation. It is designed for indoor conduit wiring and rated up to 600V. The nylon jacket protects against oil, abrasion, and chemicals, making it suitable for tight conduit runs and professional installations in both residential and light commercial projects.
6 AWG 19-Stranded THHN Green Copper Building Wire (100FT)
Stock Wire’s 100-foot green THHN 6 AWG option emphasizes the same copper conductors and protective jacket design as its black counterpart, with a color variant for grounding or identification in complex installations. The combination of annealed copper, PVC insulation, and a nylon jacket supports durable performance in both wet and dry locations when used within conduit or raceways.
Buying Guide
- Conductor material: All listed options use copper conductors, which offer superior conductivity and durability compared to aluminum.
- Insulation and jacket: THHN insulation with nylon jackets provide heat resistance, moisture protection, and abrasion resistance. Some variants also meet THWN-2 requirements for wet locations.
- Location considerations: For wet environments, THWN-2 capable cables or jackets designed for moisture exposure may be preferable. For dry indoor runs, standard THHN with nylon jackets is typically sufficient.
- Conductor count and flexibility: 19-stranded conductors offer greater flexibility for pulling through conduit and for installations with tight bends, compared to solid or fewer-strand options.
- Color coding and grounding: Black, red, white, and green variants help identify circuits and ground paths. Bare copper is often used for grounding connections specifically.
- Length and waste: Longer spools reduce waste on large projects but require proper storage and handling. Shorter cuts are convenient for small tasks but may require splicing.
- Voltage rating: Most 6 AWG THHN wires are rated up to 600V, suitable for residential feeders, subpanels, and industrial controls within standard electrical codes.
- Installation environment: Consider conduit type, weather exposure, and mechanical protection needs when choosing a jacket and insulation system.
- Standards and compatibility: Ensure products meet local electrical codes and certifications for your region and project type.
