Honeywell 47104807 Thermostat Cable

The Honeywell 47104807 is a contractor-grade 18/2 solid thermostat cable engineered for reliable low-voltage control circuits in residential and commercial HVACR applications. Featuring 18 AWG bare copper conductors, this solid conductor thermostat wire ensures superior signal integrity for wiring thermostat controls, heat pumps, and air conditioning systems. The CL2 rated cable is jacketed in a durable, brown PVC that is sunlight resistant, making it suitable for standard indoor installations and exposed runs where UV exposure is a factor.

This 500-foot reel includes a built-in braided ripcord for fast stripping and sequential footage markings to eliminate measurement guesswork during long pulls. Designed for power-limited circuits, the Genesis 47104807 is rated for up to 150V and operates within a temperature range of -20?C to 60?C. Note that while this is a high-performance HVAC control wire, it is non-plenum rated and should not be used in environmental air spaces or risers where CMP or CMR cable is required by local code.

Key Benefits

• Conductivity: 18-gauge solid bare copper provides consistent electrical performance for 24V control systems.
• Code Compliance: UL listed with a CL2 rating for safe use in non-plenum power-limited applications.
• Installation Efficiency: Packaged on a sturdy reel with integrated ripcord and footage markers for reduced labor time on the job site.
• Environmental Resilience: UV-resistant brown jacket prevents degradation in areas with incidental sunlight exposure.

Common Questions

• Is 18/2 wire enough for modern smart thermostats? While 18/2 is perfect for basic heating or cooling controls and doorbells, most WiFi-enabled smart thermostats require a "C-wire" (common wire), typically necessitating an 18/5 or 18/8 cable.
• Can this cable be used in a plenum ceiling? No, this 47104807 cable is CL2 rated. For return air plenums, you must use a CL2P (plenum-rated) equivalent.
• What is the maximum voltage for this wire? This cable is rated at 150 Volts, making it ideal for standard low-voltage HVACR signaling and power-limited circuits.
