Thomas Betts -17212-5-BD Ring Terminal 4 Awg

Product Description

The THOMAS BETTS -17212-5-BD is a ring terminal designed for 4 AWG wire with a 5/16 inch stud size. Ring terminals provide a secure, low-resistance connection point between a wire and a threaded fastener or stud. This terminal is used in electrical wiring applications where a permanent, loop-style termination is required. It carries a UL Listed rating, confirming it meets established safety standards. Licensed electricians and experienced wiring technicians are the primary installers of this type of terminal in both field and shop environments.

This ring terminal is suited for use in residential, commercial, and light industrial electrical wiring projects. It is appropriate wherever a 4 AWG conductor must terminate at a 5/16 inch stud — common applications include panel wiring, grounding connections, battery cable terminations, and equipment bonding. The UL Listed rating makes it acceptable for use in code-required installations where listed components are specified.

Compatibility

Designed as an OEM-style replacement or direct-use ring terminal compatible with 4 AWG conductors and 5/16 inch mounting studs in standard electrical termination applications.

Installation Notes

Installation is performed by a licensed electrician or qualified wiring technician. De-energize and lock out the circuit before terminating any conductor. The wire should be stripped to the correct length and fully inserted into the terminal barrel before crimping with an appropriately rated crimping tool. Follow NEC guidelines for conductor termination and torque requirements at the stud connection point.
