HVAC thermostat wire for residential

This 500-foot roll of 18 AWG thermostat wire uses solid bare copper conductors with a CMR-rated PVC jacket. It is designed for low-voltage control circuits that connect thermostats to heating and cooling equipment. The two-conductor construction suits standard single-stage HVAC installations.

Straightforward low-voltage installation

The solid copper cores hold their shape when routed through studs and around corners, which simplifies pulling and terminating. CMR rating allows vertical runs between floors without additional conduit. The white jacket is printed for easy identification, though solid wire can fatigue if repeatedly bent during rework.

Limited to low-voltage control circuits only

This cable carries thermostat signals and control power, not mains voltage or high-current loads. It cannot be used for line-voltage heating elements, motor feeds or any circuit exceeding its low-voltage rating. Installations requiring more than two conductors will need a different cable.

Questions about this item

How can I verify the 18 AWG solid copper conductors are intact after pulling the 500 ft roll?

Use a multimeter to check continuity on each conductor and measure resistance; solid 18 AWG copper should show very low ohms per 500 ft with no open circuits.

What comes in the box and what must I supply for a typical thermostat run?

The roll supplies 500 ft of 2-conductor CMR-rated PVC-jacketed wire; you will need wire strippers, connectors, and any staples or conduit required by local code.

Should I choose the 18 AWG or 20 gauge version for a standard residential thermostat?

This roll is 18 AWG solid copper; the 20 gauge reference appears only in marketing text, so the product you receive is the 18 AWG 2-conductor version.
