THHN Wire 200 FT 12AWG Black - Solid Copper Building Wire

Our review of the THHN Wire 200 FT, 12AWG, finds it to be a reliable, no-nonsense choice for electricians and DIYers who need a dependable conductor for indoor or protected outdoor runs. The single bare copper conductor and heat- and abrasion-resistant nylon sheath are the standout reasons to consider this cable: it delivers solid electrical performance and resists moisture and oil in conduit or raceway installations. For those prioritizing straightforward conductivity and durability in panel, circuit, or appliance wiring, this product provides the core functionality without frills.

Key Features

• High-quality conductor: The single bare copper conductor offers excellent conductivity for consistent electrical performance in residential and commercial wiring.
• Multiple size options: Available in 10 AWG, 12 AWG, and 14 AWG and several lengths, the range lets you pick the right size and run length for each project.
• Durable nylon sheath: The nylon jacket resists heat, abrasion, moisture, oil, and gasoline to protect the conductor in demanding environments.
• Conduit and raceway ready: This THHN wire is suitable for conduit and raceway installations, making it appropriate for panels, circuits, and appliance wiring.
• Easy to install: Supplied in manageable roll sizes, the wire is easy to cut, strip, and pull through conduit for faster installation.

Who It's For

This wire is aimed at electricians, contractors, and experienced DIY homeowners who need a reliable solid copper conductor for indoor or conduit-protected outdoor work. It suits panel wiring, branch circuits, appliance connections, and general building electrical where a durable, heat-resistant jacket is required.

Those who need flexible stranded cable, jacketed multicore assemblies, or special outdoor direct-burial rated wire should look elsewhere; this THHN is a solid single conductor intended for conduit and raceway use rather than exposed aerial or direct-bury applications.

Pros & Cons

Pros
