Thomas Betts 54163-TB Square Ring Terminal 3/0 Awg

Product Description

The THOMAS BETTS 54163-TB is a non-insulated, square ring terminal designed for compression-style terminations on 3/0 AWG conductors. The terminal body is copper with a tin nitride (TiN) contact plating that resists corrosion and supports reliable long-term conductivity under load. Measuring 1.98 inches in overall length and 0.92 inches in ring width, this terminal accepts a 5/16-inch stud and produces a mechanically secure, low-resistance connection. It is identified by an orange color code for quick AWG-size identification in the field. Electricians and electrical contractors working on heavy-gauge wiring applications will recognize this as a dependable compression lug for panel, bus, or equipment terminations.

This terminal is suited for residential, commercial, and light industrial electrical installations where 3/0 AWG copper conductors require a secure ring-style termination. Typical applications include service entrance wiring, main panel connections, generator hookups, and large motor or equipment feeds where a compression crimp is specified over mechanical set-screw alternatives. The square ring profile provides consistent contact geometry at the stud.

Key Features

• Compression connection type for a reliable, vibration-resistant crimp on 3/0 AWG wire
• Copper contact material with TiN plating for corrosion resistance and long-term conductivity
• 5/16-inch stud size accommodates standard panel and bus hardware
• Non-insulated design allows inspection of the conductor barrel after installation
• Orange color coding for fast wire gauge identification in the field
• CSA Certified, UL Listed, and RoHS Compliant

Compatibility

Designed as an OEM-style compression ring terminal for use with 3/0 AWG conductors and 5/16-inch stud hardware in standard electrical panel, bus bar, and heavy-equipment termination applications.

Installation Notes

Installation of compression ring terminals on 3/0 AWG conductors should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the circuit before beginning any termination work. Use a calibrated compression tool rated for the barrel size and conductor gauge specified by the terminal manufacturer. Do not over-insert or under-insert the conductor into the barrel before crimping, and verify the completed crimp with a pull test before energizing.
