Category: Thermostat Wire

We offer class two power limited thermostat wire for installing thermostats in home heating and air conditioning systems. Our 18 gauge thermostat cables are made with 6 soft drawn solid copper conductors secured with semi flexible PVC insulation and PVC jacketing for extra protection. These cables are available in 250 foot increments and come on a sturdy aluminum spool to make dispensing easier. This wire size is perfect for long runs and will provide the proper resistance even if the entire spool is used.
