Thomas Betts 54153-TB Square Ring Terminal 1/0 Awg

Product Description

The THOMAS BETTS 54153-TB is a non-insulated square ring terminal designed for compression connections on 1/0 AWG conductors. It features a copper contact with TiN (titanium nitride) plating and a 5/16-inch stud hole, making it suitable for high-current termination work in electrical panel, switchgear, and heavy equipment wiring applications. The terminal measures 1.83 inches in overall length and 0.75 inches in ring width, with a barrel thickness of 0.13 inches. It carries UL Listed, CSA Certified, and RoHS Compliant ratings. Licensed electricians and electrical contractors typically install this terminal when terminating large-gauge conductors to bus bars, lugs, or bolted stud connections.

This terminal is used in commercial and industrial electrical installations where 1/0 AWG copper or aluminum conductors require a secure, low-resistance bolted connection. Typical applications include panel boards, motor control centers, battery bank wiring, and heavy-duty power distribution assemblies. The pink color coding aids in quick visual identification of wire gauge during installation and inspection. The compression-style connection requires a compatible hex or indent crimping tool rated for 1/0 AWG terminals.

Key Features

• Compression connection type for reliable, gas-tight termination on 1/0 AWG wire
• Copper contact with TiN plating for corrosion resistance and improved conductivity at the contact surface
• 5/16-inch stud hole fits standard bus bar and lug stud sizes common in panel and switchgear work
• Non-insulated design for use where insulation is applied separately or not required by the assembly
• Pink color coding for fast visual gauge identification in the field
• UL Listed, CSA Certified, and RoHS Compliant for use in code-governed installations

Compatibility

Designed as an OEM-style compression ring terminal for 1/0 AWG conductors terminating to 5/16-inch stud hardware in residential, commercial, and industrial electrical assemblies.

Installation Notes

Installation must be performed by a qualified electrician in accordance with the NEC and applicable local codes. De-energize and lock out the circuit before terminating or removing any conductors. Use a calibrated compression crimping tool rated for 1/0 AWG non-insulated terminals to ensure a proper mechanical and electrical connection. Do not use a hammer or incorrect die set, as an improper crimp can result in high-resistance joints or conductor pullout.
