Thomas Betts -17215-1-BD Ring Terminal 1 Awg

Product Description

The THOMAS BETTS -17215-1-BD is a ring terminal designed for secure, permanent electrical connections on 1 AWG wire with a 1/2 inch stud size. Ring terminals of this type are crimped onto the stripped end of a conductor and then fastened to a stud, lug, or busbar, creating a low-resistance mechanical and electrical bond. This terminal is suited for heavy-gauge wiring applications where a reliable, vibration-resistant connection is required. Electricians and electrical maintenance technicians install these terminals in panel wiring, grounding assemblies, battery connections, and industrial control systems.

This ring terminal is sized for 1 AWG conductors and accepts a 1/2 inch mounting stud. Applications include service entrance wiring, grounding electrode conductors, battery cable terminations, and heavy equipment power feeds where large-gauge conductors must be reliably terminated at a fixed stud or bolt point. The terminal is sold individually, making it practical for repair work or small-quantity installations.

Key Features

• Rated for 1 AWG wire, suitable for high-current heavy-gauge conductor terminations
• 1/2 inch stud size accommodates standard lug, busbar, and battery post hardware
• Ring-style design keeps the terminal secured on the stud even if the fastener loosens slightly
• Single-piece packaging allows purchase in exact quantities needed for service work

Compatibility

Designed as an OEM-style replacement ring terminal for use with 1 AWG conductors and 1/2 inch stud termination points in electrical wiring assemblies.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize and lock out the circuit before terminating any conductor. Use a calibrated crimping tool rated for the terminal and wire gauge to ensure a proper mechanical and electrical crimp. Do not solder over a crimped ring terminal intended for crimp-only use, as this can create brittleness at the barrel.
