The APPLETON IBC-200S is a 2-inch set screw insulated bushing designed to protect wire and cable insulation at conduit terminations. This fitting threads into the end of a conduit or locates inside a knockout to provide a smooth, insulated throat that prevents conductors from chafing against bare metal edges. It is a standard component in electrical raceway installations where code compliance and conductor protection are required. Electricians install this bushing during rough-in and final trim on panel enclosures, junction boxes, and equipment terminations.
This bushing is suited for use in commercial and residential electrical installations wherever 2-inch conduit terminates at a box, enclosure, or panel. The set screw design provides a secure mechanical connection without threading into the conduit end, making it compatible with both cut and factory-end conduit. It is a practical solution for maintaining conductor integrity at termination points in accordance with NEC requirements.
Designed as an OEM-style replacement and standard-use insulated bushing for 2-inch conduit raceway systems in commercial and residential electrical installations.
Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the panel or enclosure before inserting or adjusting any conduit fitting. Tighten the set screw firmly with an appropriate hex key or screwdriver to secure the bushing in place. Inspect the insulated throat for damage before pulling conductors to ensure full protection at the termination point.
