It features a black thermoplastic insulation with a nylon jacket, making it suitable for use in conduit in both dry and wet locations. The 19-strand copper core provides flexibility during pull-in, reducing the effort required in long conduit runs. Licensed electricians and electrical contractors install this wire in commercial and residential construction, service panel feeders, branch circuits, and equipment connections where a durable, code-compliant conductor is required.\u003c\/p\u003e\u003cp\u003eThis wire is sold in 1-foot increments with a 250-foot minimum cut length and ships from a 500-foot coil. It is used in conduit or raceway installations in residential, commercial, and light industrial settings. Common applications include feeder runs to subpanels, motor branch circuits, and general-purpose wiring in electrical panels and junction boxes. The nylon jacket adds abrasion resistance, which is especially useful in tight conduit pulls or installations near machinery.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4 AWG stranded copper conductor with 19 strands for flexibility\u003c\/li\u003e\n\u003cli\u003eRated 70 amps at 600 volts for feeder and branch circuit use\u003c\/li\u003e\n\u003cli\u003eBlack thermoplastic insulation with nylon jacket\u003c\/li\u003e\n\u003cli\u003eDual-rated THHN and THWN for dry and wet location conduit use\u003c\/li\u003e\n\u003cli\u003eResistant to abrasion, heat, moisture, oil, gasoline, and sunlight\u003c\/li\u003e\n\u003cli\u003eMeets UL 83, UL 1063, CSA, RoHS, and Federal Specification A-A-59544\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in conduit or raceway systems where THHN or THWN-rated conductors are specified by code.

Always de-energize the circuit and verify the absence of voltage before making terminations or pulling wire into an energized conduit system. Use appropriate wire-pulling lubricant for long runs or conduit with multiple bends. Minimum order quantity is 250 feet; plan cut lengths accordingly before ordering.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Size\u003c\/strong\u003e: 4 AWG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 70 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 600 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConductor Material\u003c\/strong\u003e: Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCore Type\u003c\/strong\u003e: Stranded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Strands\u003c\/strong\u003e: 19\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Conductors\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Material\u003c\/strong\u003e: Thermoplastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJacket Material\u003c\/strong\u003e: Nylon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJacket Color\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature\u003c\/strong\u003e: 194 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConductor Type\u003c\/strong\u003e: THHN \/ THWN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResistance Features\u003c\/strong\u003e: Abrasion, Gasoline, Heat, Moisture, Oil, Sunlight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: UL 83, UL 1063 (MTW), CSA, RoHS Compliant, Federal Specification A-A-59544, ASTM Specifications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 250 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold In\u003c\/strong\u003e: 1-foot increments\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoil Length\u003c\/strong\u003e: 500 feet\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 20499001\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWIRE","offers":[{"title":"Default Title","offer_id":51540973617458,"sku":"20499001","price":1614.1,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/44e6e15a2e868751eaf2b48405928d56.jpg?v=1785866824","url":"https:\/\/voomisupply.com\/products\/southwire-20499001-thhn-thwn-4-awg-70a-building-wire","provider":"Voomi Supply","version":"1.0","type":"link"}
