Southwire 12 Gauge THHN Building Wire, 500-Feet
Southwire’s 12-gauge THHN building wire features stranded copper conductors housed in flame-retardant PVC insulation. Primarily designed for conduit runs in commercial and industrial settings, it is suitable for dry locations up to 90°C and wet locations up to 75°C. The flexible stranded design eases pulling through conduits and trays, supporting services, feeders, and branch circuits where reliability matters.
Paladin 12 AWG THHN/THWN-2 Copper Wire, 500′ Roll
Paladin’s 12 AWG copper wire is a stranded THHN/THWN-2 option with a PVC insulation jacket. It is suitable for use in wet or dry locations and is commonly deployed in conduit systems for outlets, switches, and other loads. The jacket and insulation combination provides durable resistance to heat, moisture, and various environmental conditions, aligning with typical commercial building requirements.
XRDS -RF 12 AWG THHN Bare Copper Grounding Wire, 100FT
This 12 AWG THHN bare copper conductor delivers high conductivity for panel wiring, grounding, and various control systems. The THHN insulation provides protection against heat and moisture, making it a versatile choice for residential, commercial, and industrial projects where reliable grounding is required.
FIRMERST 12 AWG THHN/THWN-2 Three-Color Set
FIRMERST offers a 12 AWG THHN/THWN-2 tri-wire bundle (Black, White, Green) in a 100-foot roll. The wires are stranded copper with PVC insulation and a nylon jacket, designed for dry and damp locations. The jacket enhances abrasion resistance and outdoor suitability, while the triple-color set helps with clear identification and easier conduit pulling for commercial installations.
Generic 12 Gauge THHN Copper Wire, 500 ft, Yellow
Generic 12 AWG THHN/THWN stranded copper wire comes on a 500-foot yellow reel, with dual ratings for THHN and THWN. It is designed for 600V systems and is suitable for both dry and wet locations. The nylon jacket and heat/moisture resistance support longer runs and broader environmental use.
Buying Guide
Key purchase considerations for 12 AWG THHN wire include conductor material, insulation and jacket, location type (dry or wet), temperature ratings, and intended use (distribution, grounding, or control circuits).
- Conductor type: Stranded copper offers greater flexibility and easier pulling, especially in conduit runs, compared to solid copper.
- Insulation and jacket: PVC insulation with nylon jackets provide resistance to heat, moisture, and abrasion, improving installation durability in demanding environments.
- Location rating: Dry locations typically tolerate higher temperatures; wet or damp locations require materials with appropriate moisture resistance and corrosion protection.
- Voltage and temperature ratings: Most THHN/THWN-2 wires are rated up to 600V; check the maximum operating temperature (often 90°C for dry and 75°C for wet).
- Identification and color coding: A three-color set (Black, White, Green) can simplify circuits, while color-coding helps prevent wiring errors during installation.
- Jacket materials: Nylon jackets improve abrasion resistance and flexibility, aiding long conduit pulls and resistance to chemicals or oils in industrial settings.
- Compliance: Look for UL-listed or equivalent certifications to ensure safety and compatibility with building codes and standards.
