14 AWG THHN/THWN Solid Copper 100 ft Grounding Wire - Green

In this review the 14 AWG THHN/THWN solid copper 100 ft green grounding wire is evaluated for homeowners, electricians, and small contractors who need a dependable, purpose-built grounding conductor. The single biggest reason to buy is its solid copper construction combined with high-heat PVC and nylon insulation rated for indoor and outdoor use, which makes it a straightforward choice for grounding, long installation runs, and simple repairs where a reliable, UL listed conductor is required.

Key Features

• Length and material: Includes 100 ft of solid copper conductor, providing a continuous run without splices for many residential or small commercial runs.
• Insulation: 14 AWG THHN/THWN PVC and nylon jacket offers high heat and moisture resistance, helping the wire hold up in indoor and outdoor environments.
• Voltage and temp rating: Rated for 600 V and 90 C (194 F), making it suitable for typical branch-circuit grounding and other electrical uses.
• Certifications: UL Listed and CSA certified with RoHS compliance, which gives confidence in safety and regulatory acceptance.
• Compatibility: Approved for grounding and compatible with major CATV and satellite provider installations, so it can be used where grounding continuity is required.
• Made in USA: Proudly manufactured domestically, which may matter for buyers seeking locally produced electrical components.

Who It's For

The wire is best for homeowners doing electrical repairs, electricians running grounding conductors, and small commercial or industrial projects that require a durable, UL listed 14 AWG solid copper wire for 600 V systems. It is particularly useful when a single continuous conductor is preferred for neat routing and minimal connections.

Those who should look elsewhere include projects that need stranded conductors for flexible routing, runs requiring larger gauge wire for higher current, or installations that demand bundled multi-conductor cable rather than single insulated building wire.

Pros & Cons

Pros

• Solid copper construction provides reliable conductivity and customers reported no broken strands during use.
• High-heat PVC and nylon jacket delivers good moisture and temperature resistance for indoor and outdoor rated work.
• UL and CSA listings plus RoHS and other certifications offer regulatory assurance for building and grounding applications.
• 100 ft length is convenient for many residential and small commercial runs without frequent splicing.

Cons

• As a solid 14 AWG conductor it is less flexible than stranded wire, which can make routing in tight spaces more difficult.
• Single conductor format means additional time if multiple parallel conductors or multi-conductor cable is needed for a project.

Specifications

Our Verdict

This 14 AWG solid copper THHN/THWN 100 ft grounding wire is a pragmatic, good-value choice for anyone needing a single reliable conductor for grounding or general building wire tasks. Its robust insulation, certifications, and domestic manufacture make it a sensible pick for residential, office, and light commercial work, while buyers needing greater flexibility or multi-conductor cables should consider alternate options.

Frequently Asked Questions

Is this wire suitable for outdoor grounding?
Yes. The THHN/THWN PVC and nylon jacket is rated for indoor and outdoor use and is moisture and heat resistant.

Can this replace stranded wire in tight bends?
Solid 14 AWG is less flexible than stranded wire, so it may be harder to route around tight bends; stranded wire is better for those situations.

Is the wire certified for building installations?
Yes. It is UL listed and CSA certified, with RoHS compliance, making it acceptable for many building and grounding applications.
