10 AWG THHN/THWN Stranded Copper Wire 200 ft - Durable Grounding Wire

In this review we examine the 10 AWG stranded copper THHN/THWN wire sold in a 200 ft spool. The bottom line: this is a straightforward, heavy-duty grounding and general-purpose conductor suited to residential, commercial, and light industrial wiring where a flexible, insulated copper lead is required. The reviewer found the construction and insulation to be robust, making it a reliable choice for conduit runs, feeder work, and grounding applications while offering good value for projects that need a weather-resistant, multi-use wire rated to 600 volts.

Key Features

• Stranded Copper Construction: Provides flexibility for pulling through conduit and makes the wire easier to route around bends compared with solid wire.
• THHN/THWN Insulation: The thermoplastic and nylon sheath protect against moisture and a range of temperatures for indoor and outdoor use.
• 600 Volt Rating: Rated for typical residential and commercial circuits, making it suitable for branch circuits, feeders, and control wiring.
• Works With Conduits and Trays: Sized and designed to be compatible with conduit runs and table trays used in services and machine wiring.
• Made in the USA: Measured and prepared to industry standards with attention to durability for clean or harsher installation areas.

Who It's For

This wire is best for electricians, contractors, and experienced DIYers who need a reliable 10 AWG conductor for grounding, feeders, appliance circuits, or control wiring in homes, shops, and commercial spaces. The stranded copper and THHN/THWN jacket make it particularly useful where flexibility and moisture resistance matter, such as runs through conduit or exposed routing in utility areas.

Those seeking an ultra-lightweight or ultra-flexible fine-strand cable for specialized appliances, or a color variety beyond standard jacket options, may want to compare other products. For standard 600 V rated wiring tasks where a robust copper conductor is required, this product fits most common needs.

Pros & Cons

Pros

• Solid stranded copper offers good conductivity and flexible handling for conduit pulls.
