Overview

The ABB Installation Products XJG Conduit Expansion Coupling, SKU XJG84-EMT, is engineered for EMT conduit systems requiring compensation for thermal expansion and contraction. This 3-inch coupling is designed to accommodate up to 4 inches of axial movement, preventing stress on conduit runs and connected equipment. A key feature is the integrated internal bonding jumper, ensuring continuous electrical continuity and grounding throughout the expansion joint. This is crucial for maintaining system integrity and safety in applications where conduit movement is anticipated due to temperature fluctuations or structural settling. Constructed for reliable performance, this coupling facilitates the installation of long conduit runs by absorbing movement. Its design simplifies the management of thermal expansion, a common challenge in industrial and commercial electrical installations. The 3-inch trade size is compatible with standard EMT conduit, and the 4-inch total movement capability provides significant flexibility. The internal bonding jumper is a critical component for maintaining fault current paths and ensuring proper grounding, especially in exposed or critical installations. This product is suitable for environments where conduit systems are subject to significant temperature variations, such as outdoor installations, unconditioned spaces, or areas with high heat loads.

How to Install the XJG-EMT Expansion Joint

This guide provides instructions for installing XJG-EMT Expansion Joints with Electrical Metallic Tubing (EMT). These joints are designed to accommodate longitudinal movement in conduit runs due to thermal expansion and contraction, ensuring a continuous electrical path without external bonding.

Estimated time: 15m

Tools needed:

Pipe wrench

Supplies needed:

Electrical Metallic Tubing (EMT)

  1. Insert Electrical Metallic Tubing (EMT)

    Insert the ends of the Electrical Metallic Tubing (EMT) into each end of the pre-assembled XJG-EMT Expansion Joint. The gland nut is partially tightened from the factory to facilitate easy insertion of the tubing.

  2. Tighten the Gland Nut

    Using a pipe wrench, tighten the gland nut at the end of the EMT connector. Refer to the Torque Chart for correct torque values: 90.4 N•m (800 lbl-in) for 3/4” & Smaller, 113 N•m (1000 lbl-in) for 1”, 1-1/4”, & 1-1/2”, and 181 N•m (1600 lbl-in) for 2” & Larger. This action compresses the Teflon packing, creating a rain-tight seal.

  3. Position the Internal Bushing

    Position the internal bushing in the middle of the expansion joint fitting to allow for equal movement in both directions. This ensures the joint can accommodate the full specified longitudinal movement of the tubing.
