Sold individually, this connector is constructed from one-piece, seamless, high-conductivity copper for reliable, low-resistance joints. It measures 2.130 inches in length with an inner diameter of 0.490 inches and an outer diameter of 0.617 inches. The orange color coding identifies the 3\/0 AWG conductor size at a glance, helping electricians maintain accuracy during installation. This connector is intended for copper conductors only and is not rated for aluminum or copper-clad aluminum wire.\u003c\/p\u003e\n\u003cp\u003eThis barrel connector is suited for medium-voltage distribution and power cable splicing work in residential, commercial, and industrial settings. Typical applications include underground cable joints, switchgear terminations, and utility distribution systems where a compact, seamless splice fitting is required. Licensed electricians and utility cable splicers working on copper conductor runs will find this fitting appropriate for direct-burial and conduit-installed cable assemblies operating at voltages up to 35 kV.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOne-piece seamless copper construction for consistent conductivity and mechanical strength\u003c\/li\u003e\n  \u003cli\u003eRated for use up to 35 kV on medium-voltage copper conductor systems\u003c\/li\u003e\n  \u003cli\u003eSized for 3\/0 AWG copper conductors\u003c\/li\u003e\n  \u003cli\u003eOrange color coding for quick AWG identification in the field\u003c\/li\u003e\n  \u003cli\u003eCompact profile: 2.130 inches long, 0.490 inches I.D., 0.617 inches O.D.\u003c\/li\u003e\n  \u003cli\u003eCompatible with copper conductors only — not rated for aluminum wire\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement barrel connector for medium-voltage copper conductor splicing applications requiring a 3\/0 AWG, up to 35 kV rated fitting.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician or qualified cable splicer in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and verify the absence of voltage on all conductors before beginning any splice work. Use the correct compression tooling specified for this connector size to achieve a proper mechanical and electrical connection. This connector is rated for copper conductors only — do not use on aluminum or copper-clad aluminum cable.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: Up to 35 kV\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConductor Size\u003c\/strong\u003e: 3\/0 AWG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConductor Material Compatibility\u003c\/strong\u003e: Copper only\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.130 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInner Diameter (I.D.)\u003c\/strong\u003e: 0.490 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter (O.D.)\u003c\/strong\u003e: 0.617 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-conductivity copper, seamless one-piece\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Orange\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7000031374\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51345222631730,"sku":"7000031374","price":149.44,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310535355.jpg?v=1782051973","url":"https:\/\/voomisupply.com\/products\/3m-7000031374-copper-barrel-connector-35-kv-3-0-awg","provider":"Voomi Supply","version":"1.0","type":"link"}
