It combines a 225-amp ringless socket with a 1200-amp main bus rating and a 7-terminal configuration, making it suitable for utility-grade metering work where a compact, code-compliant stack arrangement is required. Licensed electricians and utility contractors install this type of assembly during new construction or service upgrades where a pre-engineered stack reduces field fabrication time and supports inspection-ready installations.\u003c\/p\u003e\n\u003cp\u003eThis meter stack is intended for three-phase commercial and light industrial service entrances requiring a single 225-amp metering point fed from a 1200-amp main distribution bus. The ringless socket design eliminates the need for a meter ring or horn bypass, which is common in utility specifications across many service territories. The 7-terminal layout accommodates the wiring demands of a three-phase metered service with appropriate provision for both line and load conductors.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e225-amp ringless meter socket for three-phase utility metering\u003c\/li\u003e\n  \u003cli\u003e1200-amp main bus rating supports high-capacity service entrance configurations\u003c\/li\u003e\n  \u003cli\u003eSingle-position stack design simplifies installation and reduces enclosure footprint\u003c\/li\u003e\n  \u003cli\u003e7-terminal configuration accommodates three-phase line and load connections\u003c\/li\u003e\n  \u003cli\u003eRingless socket style meets common utility metering specifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style meter stack for three-phase commercial and light industrial service entrance applications requiring a single 225-amp ringless metering position on a 1200-amp distribution bus.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local utility metering requirements. De-energize and lock out the service entrance conductors before making any connections to the meter stack assembly. Verify that the utility service territory accepts the ringless socket configuration prior to installation, as some territories require specific socket types or sealing arrangements. Follow the manufacturer wiring diagram and torque all terminations to the values specified on the equipment label.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMain Bus Rating\u003c\/strong\u003e: 1200A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSocket Amperage\u003c\/strong\u003e: 225A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePhase Configuration\u003c\/strong\u003e: 3-Phase\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSocket Type\u003c\/strong\u003e: Ringless\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Positions\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTerminal Configuration\u003c\/strong\u003e: 7-Terminal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 783164194265\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: ABB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TMPR312122R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":51383328080178,"sku":"TMPR312122R","price":1894.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312672154.png?v=1782593391","url":"https:\/\/voomisupply.com\/products\/abb-tmpr312122r-meter-stack-1200a-3-phase-ringless","provider":"Voomi Supply","version":"1.0","type":"link"}
