Constructed with 18 AWG solid copper conductors in a 5-conductor configuration, it is sheathed in PVC insulation and carries a CL2 rating, making it suitable for in-wall installations where Class 2 wiring methods are required. Each reel contains 250 feet of cable, providing enough footage for most new-construction rough-ins or larger replacement runs. HVAC technicians and low-voltage control wiring installers are the primary trades that work with this product.\u003c\/p\u003e\u003cp\u003eThis thermostat cable is used to connect thermostats to HVAC control boards, air handlers, heat pumps, and zone controllers in residential and light commercial applications. The 5-conductor layout supports systems requiring separate wires for heating, cooling, fan, common, and an additional function such as a reversing valve or auxiliary heat stage. The 250-foot reel format suits both single-run installations and multiple shorter runs pulled from a common spool on the job site.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e18 AWG solid copper conductors for reliable low-voltage signal transmission\u003c\/li\u003e\n\u003cli\u003e5-conductor configuration supports multi-stage and heat pump thermostat wiring\u003c\/li\u003e\n\u003cli\u003eCL2 rated for in-wall installation per NEC Class 2 wiring requirements\u003c\/li\u003e\n\u003cli\u003ePVC outer jacket provides protection against abrasion and moisture during installation\u003c\/li\u003e\n\u003cli\u003e250-foot reel reduces waste and suits both single and multiple runs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement and new-installation thermostat cable for residential and light commercial HVAC control wiring applications requiring 18 AWG 5-conductor CL2-rated cable.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified HVAC technician or licensed low-voltage wiring contractor in accordance with NEC Article 725 Class 2 wiring requirements. Always power down the HVAC system and thermostat circuit at the breaker before connecting or disconnecting thermostat wiring. Avoid routing thermostat cable parallel to line-voltage wiring for extended runs, as induced interference can affect control signal integrity. Secure cable at appropriate intervals per local code requirements and avoid sharp bends that could damage conductors.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Gauge\u003c\/strong\u003e: 18 AWG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Conductors\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConductor Type\u003c\/strong\u003e: Solid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJacket Material\u003c\/strong\u003e: PVC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCable Rating\u003c\/strong\u003e: CL2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReel Length\u003c\/strong\u003e: 250 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Roll\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SOUTHWIRE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 18\/5cl2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWIRE","offers":[{"title":"Default Title","offer_id":51383914856754,"sku":"18\/5CL2","price":112.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312674211.webp?v=1782611653","url":"https:\/\/voomisupply.com\/products\/southwire-18-5cl2-thermostat-cable-18-awg-5-conductor-250-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
