12 Gauge Wire 100 Feet 12/2 AWG Pure Copper Wire - Flexible Low

In this review the 12 Gauge Wire 100 Feet 12/2 AWG Pure Copper Wire is evaluated for installers, hobbyists, and DIYers who need a long run of flexible, low resistance power cable. The bottom line: this wire stands out for its high-purity oxygen-free stranded copper construction and low impedance, making it a practical choice when reliable conductivity and flexibility matter. It is especially useful where long 12 AWG runs are required for solar panels, automotive circuits, LED lighting or audio power, and the review focuses on real-world handling, heat and voltage ratings, and ease of termination.

Key Features

• Material and construction: High-purity oxygen-free stranded copper provides low resistance and stable conductivity for better power transfer over longer runs.
• Length and colors: Two conductor parallel wire with 100 ft of black and 100 ft of red gives long continuous runs and clear polarity identification for installations.
• Flexibility: The 72-strand 0.24 mm strands yield a very flexible cable that is easier to route in tight spaces compared with solid core wire.
• Insulation and safety: PVC insulation with specified thickness and a 600 V rating supports a wide range of low voltage applications and elevated ambient temperatures up to 90 C.
• Ease of termination: The stranded construction is soft and simple to strip, solder or crimp, which saves time when fitting terminals or splicing.

Who It's For

This wire is aimed at automotive electricians, solar installers on small to medium systems, and audio or LED lighting enthusiasts who need a long, flexible 12 AWG run with clear color coding. The combination of oxygen-free copper and multiple fine strands suits applications where heat build-up and voltage drop must be minimized.

Those who should look elsewhere include users who must meet specialized building-code classifications for flame resistance beyond standard PVC, or projects that require insulated conductors rated above 600 V or for continuous exposure below -10 C without additional protection.

Pros & Cons

Pros

• High-purity oxygen-free copper strands yield high conductivity and low impedance ideal for long power runs.
• Extensive length and dual color coding reduce the need for additional splices or markers in most installations.
• Very flexible stranded design simplifies routing, termination and soldering for DIY and professional work.

Cons

• PVC insulation may not meet specialized fire or outdoor UV criteria for some installation environments.
