Thomas Betts 54132 Square Ring Terminal 8 Awg 3/8 Stud

Product Description

The THOMAS BETTS 54132 is a non-insulated square ring terminal designed for compression connections on 8 AWG copper conductors. It provides a secure, low-resistance termination point where a wire must be fastened to a stud or lug. The square ring geometry seats flush against mounting hardware and resists rotation during torquing, making it a reliable choice in panel terminations, grounding applications, and equipment bonding. The copper contact with titanium nitride (TiN) plating improves corrosion resistance and contact durability. Licensed electricians and electrical contractors are the primary installers of this terminal type in commercial and industrial wiring assemblies.

This terminal is suited for residential, commercial, and light industrial electrical installations where 8 AWG conductors must be terminated at a 3/8 inch stud. It is commonly used in panel boards, motor control centers, grounding electrode conductor connections, and equipment bonding points. The compression connection style requires a proper ratcheting or hex crimp tool to achieve a gas-tight, code-compliant termination. The non-insulated design allows inspection of the crimp after installation and is appropriate where insulation sleeves or heat-shrink tubing will be applied separately or where the terminal is otherwise protected by an enclosure.

Key Features

• Square ring geometry resists rotation on stud during installation and service
• Compression connection style provides a gas-tight, low-resistance crimp for 8 AWG wire
• Copper contact with TiN plating for enhanced corrosion resistance and long-term conductivity
• 3/8 inch stud size fits standard hardware used in panel boards and grounding assemblies
• Non-insulated construction allows post-crimp inspection and accommodates field-applied insulation
• CSA Certified, UL Listed, and RoHS Compliant for use in code-governed installations

Compatibility

Designed as an OEM-style compression ring terminal for 8 AWG conductors terminating at a 3/8 inch stud in standard electrical panels, grounding systems, and equipment bonding applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize the circuit and verify absence of voltage before terminating conductors. Use a calibrated ratcheting crimp tool rated for compression-style terminals and 8 AWG wire to achieve a proper gas-tight crimp. Do not attempt to solder a compression-style terminal or use pliers as a substitute for a proper crimping tool.
