  • Overall length6.5
  • Product typeCL2

Thermostat wire for low-voltage control

This 18 AWG three-conductor cable is built for thermostat and similar low-voltage control circuits. The CL2 rating allows in-wall installation in residential and light-commercial settings. Solid conductors simplify termination on screw terminals. The brown jacket provides easy visual identification in bundled runs.

Thermals noise and power draw in normal use

The cable carries up to 150 volts and remains passive during operation, so it generates no heat, noise or power draw of its own. Heat and acoustic performance depend entirely on the connected equipment. The 500-foot length supports extended runs without splices.

Questions about this item

How do I install the 18 AWG solid conductors in a thermostat, and what step is often missed?

Strip each solid copper conductor carefully, tighten the terminal screws firmly, and verify the brown jacket is rated CL2 for in-wall runs at 150 V.

What maintenance or replacement will this 500 ft CL2 thermostat wire need later?

Inspect the brown PVC jacket periodically for cracking or damage; replace the cable if the insulation becomes brittle or conductors show corrosion.
