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.
