HVAC low-voltage thermostat wire

This 18 AWG eight-conductor cable uses solid bare copper and carries a CMR riser rating for in-wall runs. The 250-foot wooden reel supplies enough length for multi-zone residential or light-commercial heating and cooling installations.

Sunlight-resistant jacket and temperature range

The brown jacket is rated for sunlight resistance from minus 20 to 60 degrees Celsius, so the cable withstands attic heat and outdoor exposure without degradation. That range lets installers route the wire through unconditioned spaces while maintaining insulation integrity.

150-volt limit and fixed conductor count

The 150-volt rating restricts use to Class 2 low-voltage circuits such as thermostats, doorbells and alarm sensors. Eight conductors are built in; projects that need more or fewer wires require a different cable type.

Questions about this item

Will the 18 AWG solid copper conductors need replacement during the cable's service life?

The 18 AWG solid copper conductors are designed for permanent installation and do not require routine replacement under normal HVAC or low-voltage use.

What is the first performance limit reached when this cable runs continuously at its 150 volt rating?

The 150 volt rating is the primary electrical limit; sustained operation must stay within this voltage to maintain insulation integrity and CMR compliance.

How much heat does the brown jacketed cable generate when powering an HVAC system all day?

The cable operates within a -20 °C to 60 °C temperature range and its low-voltage design minimises heat rise during continuous daily operation.
