18/5 Thermostat Wire for HVAC

This Logico cable supplies five solid bare copper conductors at 18 AWG for thermostat, HVAC, bell and alarm circuits. The CMR riser rating permits vertical runs between floors in residential and light commercial buildings. A 500-foot wooden reel provides enough length for whole-house wiring jobs without splices. It operates at up to 150 volts in low-voltage control applications.

CMR Rated Jacket Withstands Heat and Sunlight

The PVC jacket carries a CMR flame rating and is listed as sunlight resistant from minus 20 degrees Celsius up to 60 degrees Celsius. This temperature range lets the cable survive attic heat and cold exterior walls without cracking. Solid copper conductors hold their shape during pulls through studs and joists, reducing kinks that can increase resistance over long runs. The riser rating limits flame spread in vertical shafts.

Five Conductors on a Single 500-Foot Reel

Five colour-coded wires inside one jacket simplify multi-function thermostat connections and eliminate the need to pull separate cables. The 500-foot length equals 152 metres, matching the supplier spec for project planning. Solid 18 AWG conductors are not suited for high-flex or vibration-heavy environments such as moving machinery or automotive harnesses. Buyers needing stranded wire or higher voltage ratings should select a different cable type.

Questions about this item

Does the 18 AWG solid copper conductor generate noticeable heat on long HVAC runs?

At 150 V low-voltage rating the current stays small, so an 18 AWG solid copper core produces minimal heat even over the full 500 ft length.

What terminals or connectors are needed to terminate the five bare copper conductors?

Each of the five solid copper conductors accepts standard low-voltage screw terminals, spade lugs or push-in connectors used on thermostats and alarm panels.

Can this CMR-rated PVC jacket stay flexible when pulled through cold attic spaces at -20 °C?

Yes, the sunlight-resistant PVC jacket is rated from -20 °C to 60 °C, so it remains pliable during cold-weather installation.
