The barrel accepts a 2 AWG wire and the square ring seats on a 5\/16-inch stud. The copper contact body features a titanium nitride (TiN) plating that resists corrosion and reduces contact resistance over the service life of the connection. At 1.73 inches long and 0.59 inches wide with a 0.11-inch barrel thickness, this terminal is suited for panel wiring, grounding lugs, and heavy equipment connections where a secure mechanical and electrical bond is required. Electricians and panel technicians install this terminal using a compression crimping tool matched to 2 AWG tooling.\u003c\/p\u003e\u003cp\u003eThis terminal is used in industrial control panels, electrical distribution equipment, and commercial wiring applications that require a reliable, code-compliant ring termination at 2 AWG. The non-insulated design is appropriate where terminations are covered by a separate insulating sleeve or where exposed metal terminals are acceptable per the installation specification. The square ring profile provides stable seating on square or hex stud hardware commonly found in bus bars and grounding assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCompression connection type ensures a gas-tight crimp when applied with the correct tooling\u003c\/li\u003e\n\u003cli\u003eCopper contact with TiN (titanium nitride) plating for corrosion resistance and low contact resistance\u003c\/li\u003e\n\u003cli\u003eSquare ring profile for positive alignment on bus bar studs and grounding hardware\u003c\/li\u003e\n\u003cli\u003eNon-insulated barrel for use where insulation is not required or is provided separately\u003c\/li\u003e\n\u003cli\u003eCSA Certified, UL Listed, and RoHS Compliant\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style compression ring terminal for 2 AWG wire on 5\/16-inch stud hardware in residential, commercial, and industrial electrical installations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a compression crimping tool rated and calibrated for 2 AWG non-insulated terminals. De-energize and lock out the circuit per NFPA 70E requirements before making any termination. Strip the conductor to the correct length per the terminal barrel depth and inspect the crimp for a secure, gas-tight connection before torquing the stud fastener. Do not use this terminal with wire sizes outside the rated 2 AWG specification.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Type\u003c\/strong\u003e: Square Ring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Compression\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation Type\u003c\/strong\u003e: Non-Insulated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Wire Size\u003c\/strong\u003e: 2 AWG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStud Size\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Material\u003c\/strong\u003e: Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Plating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.73 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRing Width\u003c\/strong\u003e: 0.59 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBarrel Thickness\u003c\/strong\u003e: 0.11 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Brown\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: CSA Certified, UL Listed, RoHS Compliant\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 54142-TB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THOMAS \u0026 BETTS","offers":[{"title":"Default Title","offer_id":51541526544690,"sku":"54142-TB","price":22.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6c120c7966ea282975e999487099a2bb.jpg?v=1785878375","url":"https:\/\/voomisupply.com\/products\/thomas-betts-54142-tb-square-ring-terminal-2-awg-5-16-stud","provider":"Voomi Supply","version":"1.0","type":"link"}
