Primary wire is a general-purpose insulated conductor used for low-voltage DC wiring in automotive, marine, HVAC control circuits, and light electrical applications. At 16 AWG, this wire handles moderate current loads and is sized for runs where flexibility and reliability matter. Electricians, HVAC technicians, and automotive service pros reach for primary wire when running control wiring, sensor leads, or accessory circuits where a pre-cut length speeds up the job.\u003c\/p\u003e\n\u003cp\u003eThis wire is suited for residential and light commercial applications where a single pre-measured run is needed. Common uses include HVAC low-voltage control wiring, equipment grounding leads, panel accessory circuits, and automotive or equipment harness repair. The black jacket aids in color-coding negative or ground conductors in DC wiring systems. The carded format keeps the coil organized and untangled for quick deployment in the field or van stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e24-foot pre-cut length eliminates measuring and reduces waste on single-run jobs\u003c\/li\u003e\n  \u003cli\u003e16 AWG conductor sizing suitable for moderate current low-voltage control circuits\u003c\/li\u003e\n  \u003cli\u003eBlack insulation jacket for standard color-coding of ground or negative conductors\u003c\/li\u003e\n  \u003cli\u003eCarded packaging keeps wire coiled and ready for field use or truck stock\u003c\/li\u003e\n  \u003cli\u003eGeneral-purpose primary wire construction compatible with a wide range of low-voltage DC applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose 16-gauge primary wire for use in low-voltage DC control wiring, automotive harness repair, marine accessory circuits, and HVAC control applications where a pre-cut 24-foot conductor is appropriate.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of primary wire in electrical or HVAC control applications should be performed by a licensed electrician or qualified HVAC technician in accordance with the NEC and any applicable local codes. Always de-energize the circuit and confirm zero voltage before making or breaking connections. Use properly rated connectors, terminals, or wire nuts sized for 16 AWG conductors. Do not exceed the current-carrying capacity appropriate for the gauge and insulation type in the installation environment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Gauge\u003c\/strong\u003e: 16 AWG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 24 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Type\u003c\/strong\u003e: Primary Wire\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Format\u003c\/strong\u003e: Carded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.98 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 6\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: 55666633\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWIRE","offers":[{"title":"Default Title","offer_id":51524643389746,"sku":"55666633","price":49.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f13ce8d693f22ea46fa9ad5759a73cb.jpg?v=1785453903","url":"https:\/\/voomisupply.com\/products\/southwire-55666633-primary-wire-16-gauge-24-feet","provider":"Voomi Supply","version":"1.0","type":"link"}
