Thomas Betts -17212-4-BD Ring Terminal 4 Awg

Product Description

The THOMAS BETTS -17212-4-BD is a ring terminal designed for use with 4 AWG wire and a 1/4 inch stud. Ring terminals provide a secure, low-resistance connection between a conductor and a threaded stud or bolt. This terminal is used in electrical panel wiring, grounding applications, and equipment terminations where a mechanically fastened connection is required. Electricians and electrical assemblers install this type of terminal in both field and shop environments. The 4 AWG wire size rating and 1/4 inch stud size make it suitable for medium-gauge power and grounding circuits found in commercial and industrial electrical work.

This ring terminal is suited for residential and commercial electrical installations where 4 AWG conductors are terminated at bus bars, grounding lugs, battery systems, or control panels. It is compatible with standard 1/4 inch threaded studs and bolts. The terminal is sold individually, with a minimum order quantity of 10 units per order, making it practical for both single repairs and small batch work.

Key Features

• Compatible with 4 AWG wire for medium-gauge power and grounding applications
• 1/4 inch stud size fits standard threaded studs and bolts
• Ring-style tongue provides a secure, retained connection that resists pull-off
• Sold per piece with a minimum order quantity of 10 units

Compatibility

Designed as an OEM-style replacement and standard-use ring terminal for 4 AWG wire terminations at 1/4 inch threaded studs in residential and commercial electrical installations.

Installation Notes

Ring terminals of this type are installed by licensed electricians using a ratcheting or die-type crimping tool rated for the wire gauge. Always de-energize and lock out the circuit before terminating conductors. Ensure the correct crimp die is used for the wire gauge to achieve a gas-tight connection. Follow applicable NEC requirements for conductor termination and grounding installations.
