Appleton CSBE-400P-1 Conduit Bushing 4 Inch

Product Description

The APPLETON CSBE-400P-1 is a 4-inch conduit bushing designed to protect wire insulation at conduit termination points. Conduit bushings are installed at the end of a conduit run where conductors enter an enclosure, panel, or junction box. They provide a smooth, rounded edge that prevents abrasion damage to wire jackets during pull-through and after installation. This fitting is a standard component in commercial and industrial electrical installations wherever rigid or intermediate conduit terminates at an enclosure opening.

The CSBE-400P-1 is suited for use in commercial and industrial electrical systems where 4-inch conduit terminates at panels, motor control centers, switchgear enclosures, or similar equipment. Licensed electricians and electrical contractors install conduit bushings as a required component at conduit terminations per the National Electrical Code. The 4-inch trade size makes this bushing appropriate for large-conductor feeders and service entrance conduit runs.

Key Features

• 4-inch trade size fits standard 4-inch conduit terminations
• Protects wire insulation from abrasion at conduit entry points
• Designed for use at enclosure, panel, and junction box terminations
• Manufactured by Appleton, a recognized name in electrical fittings

Compatibility

Designed as an OEM-style replacement or new-installation conduit bushing for 4-inch rigid metal conduit or intermediate metal conduit terminations in commercial and industrial electrical systems.

Installation Notes

Installation is performed by a licensed electrician in accordance with applicable NEC requirements. De-energize the panel or enclosure before beginning work at the termination point. Thread the bushing onto the conduit end before pulling conductors, and ensure the bushing is fully seated and secured to protect conductors from the conduit edge. Do not substitute a bushing of the wrong trade size, as an improper fit will not provide adequate conductor protection.
