It provides a reliable grounding path while protecting conductors from sharp conduit edges with its insulated throat. Electricians install this bushing at panel knockouts, enclosures, and junction boxes where code requires a grounded and insulated conduit termination. The bushing fits 4-inch conduit trade size and is built to withstand the demands of commercial and industrial electrical installations.\u003c\/p\u003e\n\u003cp\u003eThis grounding bushing is used in commercial and industrial electrical systems where rigid or intermediate metal conduit terminates at enclosures, switchboards, panelboards, and pull boxes. It is a standard component in new construction and retrofit work wherever conduit grounding continuity and conductor protection are required at the termination point. Compatible part references noted in trade include Madison Electric CBGI-400 and Topaz 340, indicating common cross-reference use across electrical supply channels.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInsulated throat protects conductors from abrasion at conduit terminations\u003c\/li\u003e\n  \u003cli\u003eProvides a bonding and grounding connection point at the bushing lug\u003c\/li\u003e\n  \u003cli\u003eFits 4-inch trade size rigid metal conduit and intermediate metal conduit\u003c\/li\u003e\n  \u003cli\u003eOne year limited warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCross-references with Madison Electric CBGI-400 and Topaz 340.

De-energize all circuits at the panel before beginning termination work. Thread the bushing onto the conduit end and secure before pulling conductors through to avoid conductor damage. Connect the grounding conductor to the bushing lug and ensure a continuous bonding path to the enclosure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrade Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 9.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 6.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 9.1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.8 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: One Year Limited\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: China\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: SOUTHWIRE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CBGI400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWIRE","offers":[{"title":"Default Title","offer_id":51345267392818,"sku":"CBGI400","price":22.14,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310553053.png?v=1782053444","url":"https:\/\/voomisupply.com\/products\/southwire-cbgi400-insulated-grounding-bushing-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
