Supplied on a 250-foot spool in brown jacket, this non-plenum cable is built for low-voltage thermostat control wiring in residential and light commercial HVAC systems. The solid conductor construction supports reliable, low-resistance connections at standard thermostat terminals and control boards. HVAC technicians and electricians install this cable when running new thermostat circuits or replacing damaged wiring between a furnace, air handler, or heat pump and its wall-mounted thermostat.\u003c\/p\u003e\n\u003cp\u003eThis cable is suited for residential and light commercial HVAC control wiring where a non-plenum, in-wall or conduit installation is appropriate. The 8-conductor count accommodates multi-stage systems, heat pump applications with auxiliary and emergency heat circuits, and zoning configurations that require additional control wires. The 250-foot spool length covers most single-system residential runs and many light commercial jobs without splicing. It is not rated for use in air-handling spaces or plenum return air plenums.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18 AWG solid conductors for dependable low-voltage thermostat control circuits\u003c\/li\u003e\n  \u003cli\u003e8 conductors support multi-stage, heat pump, and zoning control wiring\u003c\/li\u003e\n  \u003cli\u003eCL2 class 2 power-limited circuit rating per NEC Article 725\u003c\/li\u003e\n  \u003cli\u003eNon-plenum jacket suitable for in-wall, conduit, and open-air installations outside air-handling spaces\u003c\/li\u003e\n  \u003cli\u003eBrown jacket for field identification and color-coding of multiple thermostat runs\u003c\/li\u003e\n  \u003cli\u003e250-foot spool reduces waste and simplifies inventory for service vehicles and job sites\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard CL2-rated, 18 AWG 8-conductor thermostat cable for use with conventional and communicating low-voltage HVAC control systems in non-plenum residential and light commercial installations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or electrician in accordance with NEC Article 725 governing class 2 power-limited circuits. De-energize all equipment at the disconnect or breaker before making any thermostat wiring connections. Route cable away from high-voltage conductors and protect runs through framing or conduit as required by local code.
