Upgrade your wiring projects with the industrial-grade performance of the Calterm 52167 Electrical Primary Wire. Specifically engineered to meet rigorous standards, this 100 ft., 16 AWG black primary wire is an essential component for any project in the Tools & Home Improvement, Electrical, and Electrical Wire categories. Whether you are executing complex automotive repairs, wiring marine equipment, or establishing a new electrical installation, this wire delivers premium conductivity and steadfast dependability. At the core of this primary wire is an ultra flex Type 3 Stranding wire design. This fine stranding structure gives the 100 percent copper wire exceptional flexibility compared to standard solid conductors, allowing you to easily bend, twist, and route the wire through tight engine bays, narrow conduits, or complex control panels without kinking. Protection is paramount in demanding environments, which is why this wire is wrapped in highly durable PVC insulation. The robust outer jacket is specially formulated so that the insulation is heat and abrasion resistant, defending the internal copper against friction and high-temperature exposure. Furthermore, it completely resists salt water, battery acid, oil, gasoline, and UV radiation. This comprehensive protection prevents premature degradation and short circuits, even when exposed to harsh sunlight, corrosive marine environments, or automotive fluids. Packaged in small spools for maximum convenience, this 100 ft. wire dispenses cleanly without tangling, saves valuable toolbox space, and ensures easy portability from job to job. Rated to 600V max, the Calterm 52167 provides the ultimate combination of flexibility, rugged environmental resistance, and heavy-duty safety for your next wiring application.
