Thomas Betts -17212-3-BD Ring Terminal 4 Awg 10 Stud

Product Description

The THOMAS BETTS -17212-3-BD is a ring terminal designed for 4 AWG wire with a No. 10 stud size. Ring terminals provide a secure, low-resistance electrical connection by looping around a screw or stud fastener. This type of terminal is used in control panels, electrical enclosures, and equipment wiring where a reliable mechanical and electrical bond is required. Licensed electricians and panel technicians install these terminals during wire termination work on branch circuits, control wiring, and grounding applications. The -17212-3-BD is sold individually per package.

This ring terminal is suited for residential and commercial electrical installations where 4 AWG conductors need to be terminated at a stud or screw connection point. Typical applications include service panels, motor control centers, HVAC equipment wiring, and grounding connections. It is appropriate for use wherever a permanent, stud-mounted termination is required on a 4 AWG conductor.

Key Features

• Accepts 4 AWG wire for a proper crimp fit without conductor damage
• No. 10 stud size provides compatibility with common screw and stud fastener diameters
• Ring-style locking design prevents terminal from pulling free under vibration or tension
• Compact form factor suitable for use in tight panel and enclosure spaces

Compatibility

Designed as an OEM-style replacement ring terminal for use with 4 AWG conductors terminated at No. 10 stud connections in electrical panels, control enclosures, and equipment wiring.

Installation Notes

Ring terminals of this type are installed by licensed electricians using a ratcheting crimp tool sized for the wire gauge and terminal series. Always de-energize the circuit and verify absence of voltage with a meter before terminating any conductor. Follow NEC requirements for conductor preparation, including proper insulation strip length and conductor inspection prior to crimping. Do not re-crimp a terminal that has already been installed and removed.
