The cable includes a foil shield for signal integrity in noise-sensitive applications and is rated for 300 volts. It ships on a 500-foot spool in a white jacket. Licensed electricians and HVAC technicians install this cable in commercial and residential buildings where air-handling plenum spaces require flame-retardant, low-smoke wiring per NEC standards.\u003c\/p\u003e\n\u003cp\u003eThis cable is suited for remote control, signaling, and power-limited circuit applications including security systems, audio and sound distribution, public address systems, intercom wiring, alarm circuits, and access control. The CL2P plenum rating qualifies it for use in HVAC air-handling spaces and return-air plenums where standard CL2 or CL3 cable is not permitted. The 500-foot spool length makes it practical for larger commercial rough-in jobs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCL2P plenum rating meets NEC requirements for installation in air-handling spaces\u003c\/li\u003e\n  \u003cli\u003e18 AWG stranded conductors for flexibility during pull and termination\u003c\/li\u003e\n  \u003cli\u003e6-conductor configuration supports multi-zone or multi-function low-voltage wiring\u003c\/li\u003e\n  \u003cli\u003eFoil shield reduces interference in security, audio, and signaling circuits\u003c\/li\u003e\n  \u003cli\u003e300-volt rating for power-limited circuit compliance\u003c\/li\u003e\n  \u003cli\u003e500-foot spool minimizes mid-run splices on larger installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in low-voltage, power-limited circuits including thermostat control, security, intercom, alarm, public address, and access control systems where a CL2P plenum-rated shielded cable is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician or qualified HVAC technician in accordance with NEC Article 725 governing Class 2 and Class 3 remote-control and signaling circuits. Verify that the plenum rating is required by local code before substituting a standard CL2 cable. De-energize all circuits before making terminations and ensure the foil shield drain wire is properly grounded at one end to avoid ground loops in shielded signal runs.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAWG\u003c\/strong\u003e: 18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConductors\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Type\u003c\/strong\u003e: Stranded Thermostat Wire\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCable Rating\u003c\/strong\u003e: CL2P (Plenum)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 300 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShield\u003c\/strong\u003e: Foil shielded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJacket Color\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpool Length\u003c\/strong\u003e: 500 feet\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: SOUTHWIRE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: p40040-1c\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWIRE","offers":[{"title":"Default Title","offer_id":51138333409586,"sku":"P40040-1C","price":382.11,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305533076.jpg?v=1778253659","url":"https:\/\/voomisupply.com\/products\/southwire-p40040-1c-18-6-plenum-shielded-thermostat-cable-500-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
