Cerrowire’s 112-4201J provides good value with durable performance. The product is 6-stranded THHN, supplied in a 500-foot reel. While the listing emphasizes ease of use and durability, it is manufactured in China. Use in dry locations, conduit, and trays where reliable copper conductivity is required for general electrical installations.
Cerrowire 112-4205J 500-Feet 6 Stranded THHN (Green)
The green THHN variant offers identical performance and value, with green insulation suitable for grounding or color-coded installations. This 500-foot reel uses a 6-stranded copper conductor, designed for use in dry environments and is manufactured in China. Reliable for fixed electrical systems and compatible with conduits and cable trays.
THHN-6-YEL-19STR-CU-500R 6 AWG Reel Yellow
This yellow THHN cable is suitable for use in conduits and cable trays for services, feeders, and branch circuits in commercial or industrial settings. It features a copper conductor and is designed for general-purpose electrical installations where color-coding can aid installation and maintenance.
Buying Guide: Key Considerations for 6 AWG THHN Wire
Choosing the right 6 AWG THHN wire involves evaluating conductor material, insulation, jacket, temperature rating, and application environment. These cables are typically flexible enough for long runs and rugged enough for conduit, cable trays, and equipment wiring.
- Conductor type and count: 6 AWG copper with 19 strands improves flexibility and current capacity. For most residential and light commercial projects, stranded copper is preferred over solid due to easier pulling through conduits.
- Insulation and rating: THHN-THWN-2 insulation allows dry and wet location performance with high temperature tolerance. Ensure the chosen wire meets local electrical codes for your installation.
- Jacket color and protection: Black jackets are common for THHN/THWN-2. Green jackets typically indicate grounding use, while yellow may be used for identification in large conduit runs. Nylon or PVC jackets add rigidity and moisture resistance.
- Length and waste management: A 500-foot reel reduces waste from splices and connections and speeds up installations for longer runs. Consider spool quality and packaging for smooth pulling.
- Environmental suitability: Consider exposure to moisture, oil, or chemicals. Some jackets offer better resistance to heat and environmental factors, which is important for outdoor or industrial settings.
- Code and compatibility: Verify compatibility with conduit types, trays, and connectors in your project’s jurisdiction. Documentation and UL listings provide assurance of compliance.
