The conductor is fully annealed bare copper with a 16-strand configuration, insulated with PVC and jacketed with nylon per the TFFN designation. Supplied on a 500-foot spool in red, this wire is used where color-coded low-voltage or control wiring is required in commercial and light industrial electrical installations. Licensed electricians and controls technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eTFFN wire is commonly used for fixture wiring, control panel wiring, and machine tool applications where a flexible, heat-resistant wire with a thin-wall nylon jacket is needed. The 18 AWG size suits low-current control circuits, lighting fixture leads, and similar applications. The red insulation supports color-coded wiring schemes in multi-conductor control installations. The 500-foot spool length is practical for larger jobs or stocking in a service vehicle or shop.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18 AWG fully annealed bare copper conductor with 16-strand configuration for flexibility\u003c\/li\u003e\n  \u003cli\u003eTFFN type with PVC insulation and nylon jacket rated to 90 degrees C dry\u003c\/li\u003e\n  \u003cli\u003e600-volt rating suitable for control and fixture wiring circuits\u003c\/li\u003e\n  \u003cli\u003eRed insulation for color-coded wiring identification\u003c\/li\u003e\n  \u003cli\u003e500-foot spool for efficient use on larger installations or stocking purposes\u003c\/li\u003e\n  \u003cli\u003eOuter diameter of 85 mil for use in conduit fill calculations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard TFFN 18 AWG replacement or new-install wire suitable for fixture wiring and control circuit applications in dry environments where 600-volt, 90-degree-C-rated stranded copper 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 the circuit and verify zero voltage with a meter before making any connections. TFFN is rated for dry locations only and must not be used in wet or damp environments. Verify conduit fill calculations using the 85-mil outer diameter when routing through conduit with 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: Fully Annealed 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\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 (Dry)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 85 mil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpool Length\u003c\/strong\u003e: 500 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Red\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Conductors\u003c\/strong\u003e: 1\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: tffn18strred500r\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THHNCU-GENERIC","offers":[{"title":"Default Title","offer_id":51268148527410,"sku":"TFFN18STRRED500R","price":148.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308908488.jpg?v=1780700375","url":"https:\/\/voomisupply.com\/products\/thhncu-generic-tffn18strred500r-tffn-18-awg-wire-500-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
