It provides a secure grounding path at conduit termination points while the insulated throat protects wire insulation from abrasion at the conduit end. Sized for 1-1\/2 inch trade size conduit, this bushing is a standard component in commercial and residential electrical rough-in work. Electricians rely on this type of fitting to meet NEC grounding continuity requirements at panel knockouts and junction box entries.\u003c\/p\u003e\u003cp\u003eThe CBGI150 is used wherever 1-1\/2 inch rigid metal conduit or IMC terminates at an enclosure, panel, or junction box requiring both grounding continuity and conductor insulation protection. It is a common fitting in commercial electrical construction, industrial panels, and service entrance work. This bushing is also cross-referenced as Madison Electric CBGI-150 and Topaz 335, making it a widely recognized replacement option across multiple supplier catalogs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eInsulated throat protects conductors from abrasion at conduit termination points\u003c\/li\u003e\n\u003cli\u003eProvides grounding continuity at enclosure knockouts per NEC requirements\u003c\/li\u003e\n\u003cli\u003eFits 1-1\/2 inch trade size rigid metal conduit and IMC\u003c\/li\u003e\n\u003cli\u003eCross-referenced with Madison Electric CBGI-150 and Topaz 335\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with 1-1\/2 inch trade size rigid metal conduit (RMC) and intermediate metal conduit (IMC).

De-energize the panel or enclosure before working at any knockout entry point. The bushing threads onto the conduit end and is tightened using a conduit bushing wrench or spanner. Verify grounding conductor connection and torque per the enclosure manufacturer instructions and applicable NEC requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrade Size\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConduit Type\u003c\/strong\u003e: Rigid Metal Conduit (RMC), Intermediate Metal Conduit (IMC)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: CBGI150\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWIRE","offers":[{"title":"Default Title","offer_id":51383615652146,"sku":"CBGI150","price":28.7,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312671862.png?v=1782602255","url":"https:\/\/voomisupply.com\/products\/southwire-cbgi150-insulated-grounding-bushing-1-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
