Thomas Betts -17216-4-BD Ring Terminal 1/0 Awg

Product Description

The THOMAS BETTS -17216-4-BD is a ring terminal designed for use with 1/0 AWG conductors and a 1/4-inch stud. Ring terminals provide a secure, low-resistance mechanical and electrical connection between a wire and a threaded stud or bolt. This terminal is suited for power distribution panels, grounding assemblies, and heavy-gauge wiring applications where a reliable, permanent termination is required. Licensed electricians and experienced wire harness technicians typically install this type of terminal using a calibrated crimping tool rated for the conductor size.

This ring terminal is appropriate for residential and commercial electrical installations where 1/0 AWG conductors are terminated to busbars, battery terminals, grounding lugs, or equipment studs. Its 1/4-inch stud hole fits standard fastener sizes found in panel boards, junction boxes, and electrical equipment enclosures. It is sold individually, making it suitable for single-termination repairs or low-volume maintenance work.

Key Features

• Accepts 1/0 AWG wire for heavy-gauge power and grounding circuits
• 1/4-inch stud hole fits standard threaded fasteners in panels and equipment
• Ring-style termination provides a secure, captive connection that resists pullout
• Sold as a single unit for spot repairs and low-volume installations

Compatibility

Designed as an OEM-style ring terminal for use with 1/0 AWG conductors terminating to 1/4-inch threaded studs in residential and commercial electrical applications.

Installation Notes

Installation should be performed by a qualified electrician in accordance with NEC requirements for conductor terminations. De-energize and lock out the circuit before stripping the conductor and crimping the terminal. Use a calibrated ratcheting crimping tool sized for 1/0 AWG to ensure a proper crimp — do not use pliers or non-rated tools. After crimping, inspect the barrel for cracks and confirm the ring seats flat against the stud before tightening the fastener.
