This interlock mechanism physically prevents two breakers from being in the on position simultaneously, a critical safety feature in transfer switch and dual-feed configurations. Licensed electricians and panel technicians install this component when code-compliant interlocking is required between main and generator or utility feed breakers. The 49GGF22H ships at 0.11 pounds, making it a lightweight hardware addition to the panel assembly.\u003c\/p\u003e\n\u003cp\u003eThe 49GGF22H is suited for residential and light commercial electrical panels where a horizontal interlock arrangement is needed. It is typically installed as part of a generator backfeed setup or a dual-source power configuration, ensuring that only one power source feeds the panel at any given time. This prevents dangerous back-feeding onto utility lines and protects personnel working on the grid.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHorizontal mounting orientation for compatible panelboard configurations\u003c\/li\u003e\n  \u003cli\u003eMechanically prevents simultaneous engagement of two circuit breakers\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.11 pounds for easy panel installation\u003c\/li\u003e\n  \u003cli\u003eSupports code-compliant generator interlock installations\u003c\/li\u003e\n  \u003cli\u003eOEM SIEMENS part for assured fit within compatible panel enclosures\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style horizontal interlock for compatible SIEMENS panelboard and loadcenter assemblies.

De-energize the panel and verify absence of voltage before beginning work. Follow the panelboard manufacturer instructions for proper breaker slot positioning and interlock alignment. Do not modify or bend the interlock mechanism, as deformation can compromise the mechanical lockout function.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Orientation\u003c\/strong\u003e: Horizontal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.11 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions (L x W x H)\u003c\/strong\u003e: 14.3 inches x 10.5 inches x 1.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78308708840\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: 49GGF22H\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIEMENS","offers":[{"title":"Default Title","offer_id":51383436869938,"sku":"49GGF22H","price":211.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312675147.jpg?v=1782596549","url":"https:\/\/voomisupply.com\/products\/siemens-49ggf22h-horizontal-interlock","provider":"Voomi Supply","version":"1.0","type":"link"}
