HVAC low-voltage thermostat cable

This 18 AWG solid bare copper wire has two conductors inside a brown PVC jacket. It comes on a 500 ft wooden reel and carries a CMR riser rating for in-wall runs. The cable is rated for 150 volts and suits heating, cooling, and bell or alarm circuits.

Pulling and terminating solid conductors

Solid 18 gauge wire keeps its shape when pushed through studs and stays put under screw terminals. The stiff cores resist nicking but can fatigue if bent sharply more than once. Cut the jacket cleanly to avoid scoring the copper, and do not exceed the minimum bend radius during installation.

CMR rating and temperature limits

The riser rating allows vertical runs between floors but does not meet plenum requirements for air-handling spaces. Operating range spans -20 °C to 60 °C, so the jacket may stiffen in extreme cold or soften in hot attics. The 150 volt ceiling restricts use to Class 2 low-voltage control circuits only.

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 of the two conductors and measure resistance per foot; values should match 18 AWG solid copper specifications.

What comes on the wooden reel and what must I supply for a typical HVAC thermostat install?

The reel contains 500 ft of 18/2 CMR-rated brown PVC jacketed solid copper cable; you will need connectors, wire nuts, and any required mounting hardware separately.

When should I choose the 18/2 CMR version instead of a different gauge or rating for my low-voltage HVAC or alarm circuit?

Select this 18 AWG 2-conductor CMR cable for runs up to 500 ft in riser spaces where a 150 V, sunlight-resistant jacket rated -20 °C to 60 °C is required.
