Description
Description
Install thermostat and HVAC control wiring in walls and risers with this 20AWG solid bare copper thermostat wire, rated CMR FT4 and C(ETL)US Listed. 20AWG is the practical choice for shorter runs and lower current systems where 18AWG is more wire than the job needs.
The sunlight resistant brown PVC jacket is the standard color for thermostat wire. For longer runs or high current loads like heat pump compressors, step up to our 18AWG thermostat wire instead. Need 2 conductors? See the 20AWG 500ft listing.
