12 AWG Solid Copper THHN/THWN Wire 200 ft - Insulated Red Jacket

In this review of the 12 AWG Solid Copper THHN/THWN wire from THE CIMPLE CO, the bottom line is simple: this is a dependable, American-made building and grounding wire suited for long runs where low voltage drop and durability matter. The reviewer found the 200 ft red jacketed roll especially useful for residential and commercial electrical work because the solid copper conductor and dual-rated PVC/nylon insulation provide reliable performance indoors or outdoors up to 600 V. If you need a straightforward, UL listed grounding or feeder wire made in the USA, this product delivers the essentials without unnecessary extras.

Key Features

• Solid copper conductor: Provides low voltage drop over long runs and excellent grounding properties for feeders and branch circuits.
• 200 ft length: Gives a long continuous run to reduce splices and simplify routing in conduit, cable trays, or service runs.
• THHN/THWN insulation: Dual-rated PVC and nylon jacketing resists heat and moisture for indoor and outdoor use at up to 600 V.
• 600 V, 20 A, 90 C rating: Suitable for standard residential, commercial, and many industrial applications without overspecifying the circuit.
• UL and CSA certified: Meets common safety approvals and includes RoHS-style certifications for quality assurance.
• Made in the USA: Manufactured domestically, which can simplify sourcing and ensure consistent quality control.

Who It's For

This wire is aimed at electricians, contractors, and experienced DIYers who need a reliable solid-copper THHN/THWN conductor for grounding, feeders, or branch circuits in homes, offices, and commercial sites. The 200 ft roll is especially handy for runs that would otherwise require multiple splices or joins, and the red jacket makes circuit identification easier on multi-wire jobs.

Those looking for multi-stranded flexibility or specialty conductors for very high-current industrial motors should look elsewhere; this product is a solid copper 12 AWG intended for typical 20 A circuits and general building wire uses rather than flex-conductor applications.

Pros & Cons

Pros

• Solid copper core offers low resistance and dependable grounding performance.
• Dual THHN/THWN jacketing is heat and moisture resistant, allowing indoor or outdoor routing.
• Long 200 ft length reduces the need for splices and speeds installation on long runs.
• UL listed, CSA certified, and made in the USA for consistent quality assurance.

Cons

• Solid conductor is less flexible than stranded wire, which can make tight bends more difficult in some conduit runs.
• Single color jacket limits on-site color options unless additional rolls are purchased.

Our Verdict

The 12 AWG 200 ft solid copper THHN/THWN wire is a practical, no-nonsense choice for electricians and contractors who need a UL listed grounding or building conductor that performs reliably over long runs. Its American manufacture, durable dual-rated insulation, and long length provide good value for typical residential, commercial, and light industrial applications; choose a stranded alternative only if you require extra flexibility for tight routing.
