THHN/THWN 14 AWG Solid Copper Wire 200 ft - Durable Orange Jacket

In this review the reviewer examines the 200 ft roll of 14 AWG solid copper THHN/THWN wire and finds it best suited for homeowners, electricians, and small contractors who need a dependable, insulated grounding or branch-circuit conductor. The single biggest reason to buy is its solid copper construction combined with a high-heat, moisture-resistant PVC and nylon jacket that makes it versatile for both indoor and outdoor 600 V installations. The reviewer notes clear build quality, easy stripping, and reliable performance across common wiring tasks.

Key Features

• Solid copper conductor: Provides consistent conductivity and mechanical strength for grounding and branch circuits in residential and commercial settings.
• THHN/THWN insulation: Dual-rated PVC and nylon jacket resists heat and moisture so the wire can be used in conduit and trays indoors or outdoors.
• 200 ft length: A long continuous run reduces the need for splices and is convenient for longer feeder or device wiring jobs.
• 600 V electrical rating: Rated for 600 volts and 90 C (194 F) making it suitable for most building wiring and equipment circuits.
• Easy to work with: Solid construction strips cleanly and feeds through conduit and table trays without excessive kinking.
• UL and CSA listed: Certified construction provides assurance for code-compliant installations and broad compatibility with common systems.

Who It's For

This wire is aimed at DIYers, professional electricians, and small contractors who need a reliable 14 AWG solid copper conductor for branch circuits, grounding, or equipment wiring. Its 200 ft length and robust insulation make it especially useful for runs in conduit, table trays, or where moisture resistance is required.

Those who should look elsewhere include installers needing stranded cable for flexible appliance leads or very tight bends, and projects that require a smaller spool length; this product is a solid conductor best used where rigidity and uninterrupted length are acceptable.

Pros & Cons

Pros

• Well made solid copper core offers dependable conductivity and mechanical strength for long runs.
• THHN/THWN PVC and nylon jacket resists heat, gas, dirt, and moisture for indoor and outdoor use.
• 200 ft roll is convenient for residential, commercial, and industrial installations without frequent splices.
• UL Listed and CSA certified, offering compatibility with common service and grounding requirements.

Cons

• Solid conductor is less flexible than stranded wire, so it is not optimal for applications that require frequent bending or movement.
