About Wire and Cable

Compare wire vs. cable and choose the right option based on gauge, number of conductors, insulation, and current rating.

Thermostat Cable

Hook up thermostats, air-conditioning units, and other low-voltage equipment. This cable is designated CL2 so it has flame-resistant insulation. The wires are solid so it stays in the shape you bend it.

Communication and Security System Cable

Often used for intercoms, speakers, and security systems, this cable is designated as CM and CL2 or CMG, so the insulation is flame resistant and approved for in-wall installation in single-level facilities.

Unshielded Stranded Wire

Use unshielded cable in applications where signal interference is not a concern.
