Wiring to Power Every Project

Whether you’re looking for electrical wires, wire cables, grounding wires, building wires, electrical cables, URD wires or low voltage wires, we have lots of options to cover all of your wiring needs. When considering your wiring choices, it’s important to understand the differences between electrical wires and electrical cables. Be sure to choose the right electrical wires and electrical cables so you can safely power all of your devices and networks.

Electrical Wires Versus Electrical Cables
Although the terms wire and cable are often used interchangeably, electrical wire is one electrical conductor and electrical cable, like your AC power cord, is a group of wires (or conductors), encased in sheathing. Our electrical cables and wire cables allow you to do everything from mounting that brand new flat screen TV on the wall, to purchasing coaxial cables to complete your next wiring project.

Wiring Types
The information printed on the sides of wire indicates its THHN/THWN, material, max voltage rating and gauge. THHN wire is one of the most common types of individual wires used in residential wiring applications. We also carry NM-B wire, Cat5e wire, Cat 6 wire, UF-B wire, bare copper wiring and Romex wires. Most wiring will be marked “CU” for copper, the most common conductor of residential electricity. Because electricity travels on the outside of copper wire, the wiring is insulated to protect against fire and shock. Older wiring could be aluminum or copper-clad aluminum.
