Thomas Betts 54858BE Rectangle Ring Terminal 1 Awg

Product Description

The THOMAS BETTS 54858BE is a non-insulated rectangle ring terminal designed for high-integrity electrical connections in demanding trade applications. It uses a compression connection method to secure 1 AWG wire with consistent, low-resistance contact. The copper contact with TiN (titanium nitride) plating resists corrosion and wear, making it suitable for environments where connection reliability is critical. At 2.97 inches long and 0.67 inches wide, with a 5/16-inch stud size, it fits standard termination points in electrical panels, motor leads, and heavy equipment wiring. Licensed electricians and industrial maintenance technicians are the primary installers.

This terminal is used in commercial and industrial electrical work where solid, uninsulated ring terminations are required. Typical applications include bus bar connections, grounding lugs, motor terminations, and panel wiring using 1 AWG copper conductors. The 5/16-inch stud hole fits commonly used fastener sizes in switchgear and disconnect panels. Its gray color aids identification in multi-conductor wiring runs. It is sold individually, making it suitable for single-point replacement or small-quantity installations.

Key Features

• Compression connection for secure, reliable 1 AWG wire termination
• Copper contact with TiN plating for corrosion resistance and durability
• Non-insulated design for use in applications requiring post-installation sleeving or bare termination points
• 5/16-inch stud size compatible with standard fasteners in panels and switchgear
• RoHS compliant construction
• Gray color coding for easy identification in wiring assemblies

Compatibility

Designed as an OEM-style compression ring terminal for 1 AWG conductors with a 5/16-inch stud size, suitable for use in commercial and industrial electrical panel, motor, and grounding applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements. De-energize and lock out the circuit before terminating or inspecting connections. Use a calibrated compression crimping tool rated for 1 AWG terminals to ensure full conductor engagement and a gas-tight crimp. Do not over-torque the stud fastener beyond the equipment manufacturer's specified value for the mounting hardware.
