It prevents two breakers from being energized simultaneously, a critical safety function in transfer switch applications and generator tie-in installations. Licensed electricians install this interlock to meet code requirements for manual transfer configurations, ensuring only one power source feeds the panel at a time. At 6.5 pounds and with a slim profile of 1 inch in depth, the CH8BSM is a compact hardware solution built for straightforward field installation.\u003c\/p\u003e\u003cp\u003eThe CH8BSM is intended for residential and light commercial electrical applications where a generator or alternate power source must be interlocked with the utility feed. It is commonly installed in CH series load centers during new construction or retrofit projects that require a manual transfer capability without a dedicated transfer switch. This approach is often used when local codes permit interlock-based generator connections.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMechanical interlock prevents simultaneous energizing of two breakers\u003c\/li\u003e\n\u003cli\u003eDesigned for CH series load centers and panelboards\u003c\/li\u003e\n\u003cli\u003eSupports code-compliant manual transfer configurations\u003c\/li\u003e\n\u003cli\u003eSlim 1-inch depth for easy fit within standard enclosures\u003c\/li\u003e\n\u003cli\u003ePackaged dimensions: 17 inches x 14.75 inches x 1 inch\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style accessory for EATON CH series load centers and panelboards.

Always shut off utility power and verify the panel is de-energized before installing or adjusting interlock hardware. Follow the load center manufacturer instructions for proper breaker positioning and interlock mounting. Do not force or modify the interlock mechanism, as improper installation can defeat its safety function.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 17 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 14.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78211309960\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: EATON\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CH8BSM\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51383899717938,"sku":"CH8BSM","price":550.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312675612.jpg?v=1782611102","url":"https:\/\/voomisupply.com\/products\/eaton-ch8bsm-mechanical-interlock-ch-series","provider":"Voomi Supply","version":"1.0","type":"link"}
