It features bare copper conductors with PVC insulation and a PVC outer jacket, making it a standard choice for low-voltage control wiring in residential and light commercial HVAC systems. The cable is UL and ETL listed, meeting the CL2 classification required for in-wall thermostat wiring runs. HVAC technicians and installers use this wire to connect thermostats, zone controllers, and control boards to heating and cooling equipment. The 250-foot spool provides enough length for multiple residential jobs or a single larger commercial run.\u003c\/p\u003e\n\u003cp\u003eThis cable is suited for low-voltage thermostat and control circuit installations in forced-air furnaces, air handlers, heat pumps, and zone control systems. The 4-conductor configuration supports common heating and cooling wiring configurations, including systems that require separate heating, cooling, fan, and common wire runs. It is appropriate for both new construction and retrofit applications where in-wall or exposed conduit routing is used. The temperature rating of -20 to 60 degrees F covers standard installation environments in unconditioned spaces such as attics and crawlspaces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18 AWG bare copper conductors for reliable low-voltage signal transmission\u003c\/li\u003e\n  \u003cli\u003e4-conductor configuration supports standard HVAC control wiring layouts\u003c\/li\u003e\n  \u003cli\u003eCL2-rated for in-wall low-voltage wiring installations per NEC requirements\u003c\/li\u003e\n  \u003cli\u003eUL and ETL listed for compliance with common inspection requirements\u003c\/li\u003e\n  \u003cli\u003ePVC insulation and PVC jacket resist moisture and physical abrasion\u003c\/li\u003e\n  \u003cli\u003e250-foot spool packaging reduces waste and simplifies job-site handling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard CL2-rated low-voltage control cable for use with residential and light commercial thermostats, zone controllers, and HVAC control boards that accept 18 AWG thermostat wire.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified electrician in accordance with NEC Article 725 for Class 2 low-voltage wiring. Power down the HVAC system at the disconnect or breaker before making any wire connections. Avoid routing thermostat wire in the same conduit as line-voltage wiring, as interference can affect control signal integrity. Secure the cable at appropriate intervals and protect it from physical damage in exposed locations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConductor Material\u003c\/strong\u003e: Bare Copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConductor Size\u003c\/strong\u003e: 18 AWG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Conductors\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCable Length\u003c\/strong\u003e: 250 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulation Material\u003c\/strong\u003e: PVC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJacket Material\u003c\/strong\u003e: PVC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: -20 to 60 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCable Type\u003c\/strong\u003e: CL2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Type\u003c\/strong\u003e: Spool\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 27 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: UL, ETL\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HONEYWELL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 84203\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HONEYWELL","offers":[{"title":"Default Title","offer_id":51284090847538,"sku":"84203","price":97.72,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277592.webp?v=1781068309","url":"https:\/\/voomisupply.com\/products\/honeywell-84203-thermostat-wire-18-awg-4-conductor-250-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
