Built to accept 3\/0 AWG wire, this terminal provides a reliable mechanical and electrical bond between heavy-gauge conductors and 1\/2 inch stud fasteners. Ring terminals of this type are standard hardware in commercial, industrial, and marine electrical installations where large-conductor terminations are required. Electricians and electrical contractors install these terminals using a proper ratcheting or hydraulic crimping tool sized for the 3\/0 AWG range to ensure a gas-tight crimp connection.\u003c\/p\u003e\n\u003cp\u003eThis terminal is suited for use in panel boards, bus bar connections, battery cable assemblies, grounding systems, and heavy equipment wiring where 3\/0 AWG conductors terminate at a bolted stud connection. The 1\/2 inch stud hole accommodates standard hardware sizes commonly found in electrical enclosures and power distribution equipment. It is appropriate for both new installation and repair work in residential service entrance, commercial power distribution, and industrial control applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAccepts 3\/0 AWG wire for heavy-duty, high-current conductor termination\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch stud hole fits standard bolted connection points in panels and bus bars\u003c\/li\u003e\n  \u003cli\u003eRing-style terminal provides full 360-degree stud contact for a secure, vibration-resistant connection\u003c\/li\u003e\n  \u003cli\u003eCrimp-style installation compatible with standard 3\/0 AWG crimping tooling\u003c\/li\u003e\n  \u003cli\u003eCompact form factor suitable for use inside enclosures and tight terminal blocks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation ring terminal for 3\/0 AWG conductors terminating at 1\/2 inch stud connections in electrical panels, grounding assemblies, battery systems, and power distribution equipment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with NEC guidelines for large-conductor terminations. De-energize and lock out the circuit before stripping the conductor and seating it in the terminal barrel. Use a calibrated ratcheting or hydraulic crimping tool rated for 3\/0 AWG to achieve a proper gas-tight crimp. Do not use open-barrel or undersized tooling, as an improper crimp can result in high resistance connections and potential failure under load.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Wire Size\u003c\/strong\u003e: 3\/0 AWG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStud Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 per package\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: THOMAS BETTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 17221-BD\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THOMAS \u0026 BETTS","offers":[{"title":"Default Title","offer_id":51541732032818,"sku":"17221-BD","price":106.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_b3df532c-fcbc-44e4-a50b-b5066825e263.jpg?v=1785883409","url":"https:\/\/voomisupply.com\/products\/thomas-betts-17221-bd-ring-terminal-3-0-awg","provider":"Voomi Supply","version":"1.0","type":"link"}
