The ORBIT INDUSTRIES RB-150/125 is a reducing bushing designed to connect conduit or fitting runs where a transition from a 1-1/2 inch trade size to a 1-1/4 inch trade size is required. Reducing bushings of this type are a standard component in electrical raceway systems, allowing electricians to adapt larger knockout openings or fittings to accommodate smaller conduit runs without replacing the enclosure or fitting. The RB-150/125 provides a straightforward, code-acceptable method for reducing trade sizes in place.
This reducing bushing is suited for use in residential, commercial, and light industrial electrical installations wherever conduit trade size reductions are needed at enclosures, junction boxes, panel knockouts, or conduit bodies. It is installed by licensed electricians during raceway assembly or panel termination work and is appropriate for both new construction and retrofit applications.
Designed as an OEM-style replacement or standard-fit reducing bushing for electrical conduit systems requiring a 1-1/2 inch to 1-1/4 inch trade size transition at enclosures, junction boxes, or conduit fittings.
Installation is performed by a licensed electrician in accordance with applicable NEC requirements. De-energize all circuits and verify the panel or enclosure is fully powered down before working at any knockout or termination point. Ensure the knockout opening matches the 1-1/2 inch trade size before seating the bushing. Do not force or overtighten the bushing into fittings not rated for reducing inserts.
