Manufactured as a single-piece, seamless unit from high-conductivity copper, this lug delivers reliable electrical continuity and mechanical strength at the termination point. It features a 1\/2-inch stud size, a 0.490-inch inside diameter, and a barrel length of 3.130 inches, making it well suited for 3\/0 AWG copper conductors. Licensed electricians and utility technicians install this lug in medium-voltage distribution and termination assemblies where consistent, low-resistance connections are required.\u003c\/p\u003e\n\u003cp\u003eThis lug is intended for use with copper conductors only and is appropriate for medium-voltage cable termination work in both commercial and industrial electrical systems. Its long-barrel design provides extended contact area between the conductor and lug body, supporting secure mechanical crimping. Typical applications include switchgear terminations, transformer connections, and medium-voltage cable splicing where up to 35 kV insulation class is specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOne-piece seamless construction eliminates potential failure points at weld seams\u003c\/li\u003e\n  \u003cli\u003eHigh-conductivity copper material supports low-resistance electrical terminations\u003c\/li\u003e\n  \u003cli\u003eRated for use up to 35 kV in medium-voltage applications\u003c\/li\u003e\n  \u003cli\u003eLong-barrel design provides increased conductor contact area for reliable crimps\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch stud hole accommodates standard fastener hardware\u003c\/li\u003e\n  \u003cli\u003eSized for 3\/0 AWG copper conductors with a 0.490-inch inside diameter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 3\/0 AWG copper conductors only in medium-voltage termination assemblies rated up to 35 kV.

De-energize and verify the absence of voltage on all conductors before beginning termination work. Use a calibrated crimping tool rated for the conductor size and lug type to ensure a proper mechanical and electrical connection. Do not install on aluminum conductors, as this lug is rated for copper conductors only.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConductor Size\u003c\/strong\u003e: 3\/0 AWG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: Up to 35 kV\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.490 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Length\u003c\/strong\u003e: 3.130 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStud Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Seamless high-conductivity copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConductor Compatibility\u003c\/strong\u003e: Copper only\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 pounds\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: 7000031400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51347586810162,"sku":"7000031400","price":181.6,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310535387.jpg?v=1782108962","url":"https:\/\/voomisupply.com\/products\/3m-7000031400-copper-long-barrel-lug-3-0-awg-35-kv","provider":"Voomi Supply","version":"1.0","type":"link"}
