This assembly integrates a revenue-grade meter socket and a main breaker section into one enclosure, eliminating a separate disconnect. The main breaker section is configured for 1-phase, 3-wire service and features bottom-feed conduit entry. Units like this are typically installed at the service entrance by a licensed electrician where the utility meter and main overcurrent protection must occupy a single footprint.\u003c\/p\u003e\n\u003cp\u003eThis meter main combination is suited for residential or light commercial service entrance applications requiring a 400-amp main breaker in a single integrated enclosure. Bottom-feed configuration accommodates underground service lateral installations, a common arrangement in newer residential construction and in utility districts that require underground distribution. The 42kAIC interrupt rating meets the fault current requirements of most residential and light commercial services.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e400-amp main breaker section with 42kAIC interrupting rating\u003c\/li\u003e\n  \u003cli\u003eSingle-phase, 3-wire (1P-3W) configuration for standard residential service\u003c\/li\u003e\n  \u003cli\u003eIntegrated meter socket and main breaker in one enclosure\u003c\/li\u003e\n  \u003cli\u003eBottom-feed conduit entry for underground service lateral connections\u003c\/li\u003e\n  \u003cli\u003eGE-style 400-amp main breaker section included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style service entrance combination unit for single-phase residential and light commercial applications requiring an integrated meter main with a 400-amp main breaker and bottom-feed entry.\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 requirements. Confirm with the serving utility that meter socket jaw configuration and sealing provisions meet their specifications before installation. De-energize the service lateral at the utility disconnect point before any work begins. Do not energize the unit until all conductors are properly landed, the enclosure is sealed, and the authority having jurisdiction has approved the installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePhase Configuration\u003c\/strong\u003e: 1-phase, 3-wire (1P-3W)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 400 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterrupting Capacity\u003c\/strong\u003e: 42,000 AIC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFeed Configuration\u003c\/strong\u003e: Bottom feed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 783164306996\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: TMPSB4R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":51383053025586,"sku":"TMPSB4R","price":2763.69,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312672030.png?v=1782586701","url":"https:\/\/voomisupply.com\/products\/abb-tmpsb4r-meter-main-400a-1-phase-42kaic-bottom-feed","provider":"Voomi Supply","version":"1.0","type":"link"}
