The two-hole NEMA mounting configuration ensures proper alignment to standard bus bars and equipment pads. The bell-end entry guides the conductor into the barrel during installation, reducing strand damage and improving crimp integrity. This lug is intended for installation by licensed electricians working on medium-to-heavy feeder circuits in commercial, industrial, and utility service environments.\u003c\/p\u003e\u003cp\u003eThis compression lug is suited for terminating 250 MCM copper conductors at switchgear, panelboards, transformers, and large motor terminals. The long-barrel design provides additional surface area for the compression crimp, making it appropriate for installations where vibration resistance and pull-out strength are critical. It is color-coded yellow for quick conductor size identification in the field.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLong-barrel design increases crimp contact area for improved mechanical and electrical performance\u003c\/li\u003e\n\u003cli\u003eBell-end entry guides conductor strands and reduces damage during termination\u003c\/li\u003e\n\u003cli\u003eTwo-hole NEMA mounting pattern aligns to standard bus bars and equipment lugs\u003c\/li\u003e\n\u003cli\u003eYellow color coding allows fast visual identification of 250 MCM conductor size\u003c\/li\u003e\n\u003cli\u003eCopper construction ensures high conductivity and corrosion resistance at the termination point\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style compression termination lug for use with 250 MCM copper conductors in standard NEMA two-hole mounting applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified electrician in accordance with NEC requirements for conductor terminations. De-energize and lock out the circuit before beginning work. Use a calibrated compression tool sized and set for 250 MCM copper lugs to achieve the correct crimp — do not use an uncalibrated or undersized tool. Verify that the mounting hardware torque meets the equipment manufacturer's terminal specifications prior to energizing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConductor Size\u003c\/strong\u003e: 250 MCM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConductor Material\u003c\/strong\u003e: Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLug Type\u003c\/strong\u003e: Compression\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBarrel Style\u003c\/strong\u003e: Long Barrel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEntry Style\u003c\/strong\u003e: Bell End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Holes\u003c\/strong\u003e: 2 Hole NEMA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor Code\u003c\/strong\u003e: Yellow\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NSI INDUSTRIES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: L250NB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NSI INDUSTRIES","offers":[{"title":"Default Title","offer_id":51383993893170,"sku":"L250NB","price":35.61,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312671561.png?v=1782614452","url":"https:\/\/voomisupply.com\/products\/nsi-industries-l250nb-copper-compression-lug-250-mcm-2-hole","provider":"Voomi Supply","version":"1.0","type":"link"}
