Abb HC103 1 Inch Steel Set Screw Conduit Connector

Product Description

The ABB HC103 is a 1-inch steel set screw conduit connector designed for securing rigid metal conduit or IMC to electrical enclosures, junction boxes, and panel knockouts. This type of connector uses a set screw fastening method to hold the conduit firmly in place without threading, making it a common choice for trade electricians working in commercial and industrial installations. The steel construction provides durability in standard indoor and sheltered outdoor applications where mechanical protection of wiring is required.

The HC103 is suited for use in residential, commercial, and light industrial electrical installations where 1-inch rigid metal conduit or intermediate metal conduit is run into boxes, enclosures, or panels. Electricians install this connector when transitioning conduit into a metal enclosure and a secure, non-threaded connection point is needed. It is a standard component in conduit wiring systems governed by NEC requirements.

Key Features

• 1-inch trade size fits standard rigid metal conduit and IMC
• Set screw fastening method for quick, tool-assisted conduit securing
• Steel construction for mechanical durability in typical wiring environments
• Compatible with standard knockout openings on electrical enclosures and junction boxes

Compatibility

Designed as an OEM-style replacement and standard-use fitting for 1-inch rigid metal conduit and IMC systems in commercial and residential electrical installations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code. De-energize all circuits in the enclosure before beginning any conduit termination work. Insert the conduit through the connector body and tighten the set screw with an appropriate screwdriver or hex key to secure the conduit. Ensure the connector is properly seated in the knockout opening and the locknut is tightened against the enclosure wall to maintain a solid mechanical connection.
