It is designed for use in control wiring, low-voltage applications, and panel wiring where a color-coded conductor is required. The wire carries a 600-volt rating and a 90 degrees C temperature rating, making it suitable for a wide range of indoor electrical installations. It ships on a 500-foot spool, providing enough length for larger jobs or stocking in a service vehicle. Licensed electricians and electrical contractors are the primary installers of this product.\u003c\/p\u003e\n\u003cp\u003eThis wire is commonly used in residential and light commercial control panel wiring, motor control centers, and switchboard applications. The purple color coding supports organized, easy-to-trace wiring in multi-conductor installations. The 16-strand configuration provides flexibility during routing through conduit or around tight bends in enclosures. It is well suited for branch circuit control wiring, thermostat wiring, and other low-current signal applications where TFFN-rated wire is specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18 AWG stranded copper conductor with 16-strand configuration for added flexibility\u003c\/li\u003e\n  \u003cli\u003ePVC insulation with nylon jacket rated TFFN type for durability in conduit\u003c\/li\u003e\n  \u003cli\u003e600-volt rating supports a broad range of control and signal wiring applications\u003c\/li\u003e\n  \u003cli\u003e90 degrees C temperature rating suitable for indoor panel and conduit installations\u003c\/li\u003e\n  \u003cli\u003ePurple color coding for clear conductor identification in multi-wire installations\u003c\/li\u003e\n  \u003cli\u003e500-foot spool quantity minimizes mid-job splicing and supports stocking needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose TFFN-type 18 AWG stranded control wire suitable for use in conduit, panels, and enclosures where 600-volt, 90 degrees C rated single-conductor wire is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize all circuits before making connections and verify with a meter before handling conductors. TFFN wire is rated for use in conduit or enclosed raceways and should not be used as a direct-burial or exposed outdoor conductor unless additional protection is provided. Follow conduit fill requirements per NEC Chapter 9 when routing alongside other conductors.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConductor Material\u003c\/strong\u003e: Copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConductor Size\u003c\/strong\u003e: 18 AWG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStranding\u003c\/strong\u003e: 16 Strand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulation Material\u003c\/strong\u003e: PVC with Nylon Jacket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Type\u003c\/strong\u003e: TFFN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 600 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: 90 degrees C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Conductors\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Purple\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpool Length\u003c\/strong\u003e: 500 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 85 mil\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: THHNCU-GENERIC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: tffn18strpur500r\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THHNCU-GENERIC","offers":[{"title":"Default Title","offer_id":51267887595826,"sku":"TFFN18STRPUR500R","price":148.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308908718.jpg?v=1780693397","url":"https:\/\/voomisupply.com\/products\/thhncu-generic-tffn18strpur500r-tffn-18-awg-wire-500-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
