Rated at 400A, this panel is built to handle high-capacity electrical loads across a 54-space configuration, making it suitable for larger service entrance installations. The unit ships as a single pack and is installed by licensed electricians during new construction or service upgrade projects where underground utility feed is required.\u003c\/p\u003e\n\u003cp\u003eThis load center is designed for underground power feed (UPB) configurations in 3-phase, 4-wire electrical services. The 54-space capacity accommodates a large number of branch circuits, supporting multi-tenant residential buildings, light commercial facilities, and similar applications that require substantial circuit distribution. Its main circuit breaker configuration provides overcurrent protection at the service entrance level.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e400-amp main circuit breaker rating for high-capacity service entrance installations\u003c\/li\u003e\n  \u003cli\u003e54-space panel accommodates a large number of branch circuit breakers\u003c\/li\u003e\n  \u003cli\u003e3-phase, 4-wire (3P4W) configuration for commercial and multi-family residential use\u003c\/li\u003e\n  \u003cli\u003eUnderground feed (UPB) design for below-grade utility service entry\u003c\/li\u003e\n  \u003cli\u003eSingle-pack unit sized for direct installation at the service entrance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style load center for 3-phase, 4-wire underground-feed service entrance applications requiring a 400A main breaker and 54-space branch circuit capacity.\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 all applicable local codes. Ensure utility power is de-energized and the service entrance is fully isolated before beginning any wiring work. The enclosure dimensions should be verified against the available rough-in space prior to mounting, given the unit measures approximately 68.898 inches x 15.748 inches x 7.480 inches. Do not energize the panel until all wiring connections have been inspected and torqued per the terminal manufacturer labels inside the enclosure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 400 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePhase Configuration\u003c\/strong\u003e: 3-phase, 4-wire (3P4W)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFeed Type\u003c\/strong\u003e: Underground (UPB)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Spaces\u003c\/strong\u003e: 54\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 68.898 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 15.748 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 7.480 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 47.091 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePack Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 88762166350\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: SIEMENS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: P1X54MC400CT\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIEMENS","offers":[{"title":"Default Title","offer_id":51383884972338,"sku":"P1X54MC400CT","price":4224.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312677615.jpg?v=1782610606","url":"https:\/\/voomisupply.com\/products\/siemens-p1x54mc400ct-400a-3-phase-load-center-54-space","provider":"Voomi Supply","version":"1.0","type":"link"}
