10 AWG Solid Copper Grounding Wire 25 ft - Durable THHN/THWN

Our review of this 10 AWG solid copper grounding wire finds it best suited for installers and DIYers who need a reliable, short run of grounded conductor for electrical, satellite or CATV work. The single biggest reason to buy is simple: it combines solid copper conductance with a green THHN/THWN jacket rated for indoor and outdoor use, so it handles grounding and general-purpose building wiring tasks without fuss. Packaging delivers 25 ft of jacketed wire that is heavy enough for 30 Amp circuits and remains flexible enough for routing in conduit or along walls.

Key Features

• Length and material: 25 ft of solid copper provides a continuous, corrosion-resistant conductor ideal for grounding and short runs without splices.
• Insulation: The PVC and nylon THHN/THWN jacket is high heat and moisture resistant, protecting the conductor in damp or hot environments.
• Voltage and temp rating: Rated 600 Volt and 90 C (194 F), making it suitable for many residential and commercial installations.
• Compatibility: Approved for common CATV and satellite systems, so it can be used when a grounded path is required for antenna or dish installs.
• Certifications: UL Listed and CSA certified with RoHS compliance gives confidence in safety and manufacturing controls.
• Versatility: Indoor and outdoor rated construction makes this wire useful across home, office, and industrial settings.

Who It's For

This wire is ideal for electricians, satellite and cable technicians, and knowledgeable DIYers who need a short, dependable run of grounding or building wire where a 10 AWG solid conductor is appropriate. Its green jacket makes it easy to identify as grounding in many installations.

It is not aimed at projects requiring long spool runs or stranded wire for high-flex motion applications; those needing continuous lengths beyond 25 ft or repeated flexing should look for longer spools or stranded conductors designed for vibration or moving parts.

Pros & Cons

Pros

• Solid copper core gives excellent conductivity and long-term durability for grounding tasks.
• THHN/THWN PVC and nylon jacket resists heat and moisture for indoor and outdoor use.
• UL and CSA certifications provide assurance of meeting common safety standards.
• 25 ft length is convenient for many residential and commercial short-run installations.

Cons

• Only 25 ft; not suitable if you need longer continuous lengths without splices.
• Solid conductor is less suitable than stranded wire for applications that require frequent bending or dynamic movement.
