18/4 Thermostat Wire 500 ft Roll

This Logico thermostat wire is a 500-foot roll of 18-gauge solid bare copper cable with four conductors. It carries a CMR riser rating and a 150-volt rating for low-voltage circuits. The PVC jacket is sunlight resistant across a range of minus 20 to 60 degrees Celsius. It ships on a wooden reel in brown.

Installers wiring HVAC thermostats

The solid 18 AWG conductors suit standard thermostat and bell alarm runs where CMR-rated cable is required. Buyers needing stranded conductors for frequent flexing should consider a different wire type. Projects requiring plenum-rated CMP jacket material will not meet code with this CMR cable. The four-conductor layout does not support systems needing five or more wires.

Wooden reel and brown PVC jacket

The 500-foot length on a wooden reel allows long continuous pulls without splices. Brown PVC jacket colour helps identify the cable in multi-wire bundles. Sunlight resistance permits limited outdoor or exposed routing between minus 20 and 60 degrees Celsius. No connectors, tools or software are included in the package.

Questions about this item

What low-voltage system voltage must my HVAC or alarm panel supply for this 150-volt-rated wire?

Your control panel must operate at or below 150 volts; the cable is rated for 150 V maximum.

Can I pull this solid 18 AWG cable through conduit that already contains older stranded thermostat wire?

Yes, the PVC CMR jacket is compatible with existing low-voltage wiring in the same raceway.

How do I verify the cable is performing correctly after installation?

Measure continuity on each of the four conductors and confirm the HVAC or alarm system responds at all thermostat points.
