Abb BU505 Plastic Conduit Bushing 1-1/2 Inch 25 Pack

Product Description

The ABB BU505 is a plastic conduit bushing sized for 1-1/2 inch trade size conduit. Conduit bushings protect wire and cable insulation from abrasion at conduit termination points, fitting over the threaded end of rigid metal conduit or IMC where it enters a knockout or enclosure. This bushing installs at the end of a conduit run to provide a smooth, rounded edge that prevents conductor insulation damage. Electricians use these on commercial and residential panel terminations, junction boxes, and enclosure entries. Sold in a 25-pack, the BU505 is a standard stocking item for electrical contractors and service technicians.

The BU505 is suited for use in conduit termination applications where a low-cost, lightweight plastic bushing meets code requirements. Common install scenarios include branch circuit conduit runs entering load centers, pull boxes, and equipment enclosures. The 25-pack format supports job-site inventory and bulk panel work. Applications include both new construction rough-in and retrofit conduit termination work across residential, commercial, and light industrial settings.

Key Features

• 1-1/2 inch trade size fits standard rigid metal conduit and IMC threaded ends
• Plastic construction provides lightweight, corrosion-resistant performance
• Smooth interior edge protects conductor insulation from abrasion at box entry
• 25-pack quantity supports bulk installation and job-site stocking
• Compact pack dimensions support easy storage and transport

Compatibility

Designed as an OEM-style replacement bushing for 1-1/2 inch trade size rigid metal conduit and IMC termination applications in standard electrical enclosures and knockouts.

Installation Notes

Installation is performed by a licensed electrician in accordance with NEC requirements for conduit terminations. De-energize the circuit and verify zero voltage before pulling conductors through the conduit. Thread or press the bushing onto the conduit end before inserting conductors to prevent insulation damage at the knockout edge. Inspect the bushing seating before final conductor pull to confirm it is fully seated and will not shift during wire installation.
