Nassau Electrical Supply: 100FT 2 AWG THHN
The Nassau 100-foot THHN/THWN2 copper building wire is designed for versatile electrical installations. Copper construction ensures good conductivity, while the 600V rating supports typical branch-circuit and feeder applications. The black jacket provides a classic, low-visibility appearance in finished spaces. Useful for longer runs where continuity and resistance to heat are critical. It is suitable for both wet and dry locations as THHN/THWN2 standards allow flexibility in conduit systems.
Nassau Electrical Supply: 25FT 2 AWG THHN (Black)
This 25-foot length offers a compact option for short runs or tight spaces where a continuous pull is impractical. It maintains THHN/THWN2 copper construction and a 600V rating, providing reliable performance for dry and damp environments. The black jacket blends well with many electrical installations, though always verify jacket compatibility with conduit requirements and local code standards for your project.
2 AWG 19-Stranded THHN Black Copper (50 ft)
Stock Wire offers 2 AWG THHN/THWN copper with a 50-foot cut. The wire is annealed (soft copper) to ease pulling through conduits. The insulation is high heat and moisture resistant PVC, suitable for both wet and dry locations. The flexible, easy-pull design helps reduce installation fatigue on longer conduit runs, and the black jacket provides a clean, uniform appearance in installations where jacket color matters.
Nassau Electrical Supply: 25FT 2 AWG THHN White
The white variant of Nassau’s 2 AWG THHN is useful for color-coded installations where traceability and identification are important. It shares the same THHN/THWN2 copper construction and a 600V rating, making it suitable for use in damp or dry environments when installed in compliant conduit systems. Consider color coding for specific circuits or appliance runs to enhance safety and serviceability.
2 AWG 19-Stranded THHN White Copper (25ft)
TESEU’s 2 AWG THHN white copper wire offers versatility for wet or dry locations with annealed copper and PVC insulation. The 25-foot cut size is well-suited for shorter, readily accessible runs or as a drop-in alternative for panel or equipment connections. The white jacket aids in identification and maintenance, aligning with common electrical-color-coding practices in residential and light commercial projects.
Buying Guide: Key Considerations For 2 AWG THHN Wire
- Conductor material: All listed options use copper (preferred for low resistance and durability) versus aluminum. Copper THHN/THWN2 is standard for most residential and commercial wiring.
- Insulation and jacket: THHN/THWN2 insulation is rated for dry or wet locations, and PVC jackets provide moisture resistance and chemical tolerance. Nylon or other jackets are noted for easier pulling in some options.
- Voltage rating: Most common branch-circuit wiring uses 600V rated THHN/THWN2. Verify the voltage rating matches your project’s requirements and conduit rules.
- Location: Wet vs. dry locations influence insulation choices. Some options are explicitly listed as suitable for both, while others may be best in dry interiors or protected channels.
- Length and pulling: Longer lengths reduce splicing, but longer pulls require careful planning. Soft annealed copper improves flexibility for easier installation, especially in tight conduits.
- Color coding: Black and white jackets are typical for different phases or neutral runs. White often indicates a particular circuit or location, so color-coding can aid future maintenance.
- Code compliance: Ensure the chosen wire meets local electrical codes (NEC in the U.S.) and your project’s specifications, including ampacity, conduit size, and grounding considerations.
- Quality signals: Look for copper purity, jacket durability, and consistent insulation thickness. Reputable brands and product annotations can indicate reliable performance in installation.
- Application scope: For feeders or large branch circuits, confirm the conductor size, temperature rating, and enclosure compatibility to prevent overheating and voltage drop concerns.
