Thomas Betts RB14-516 Ring Terminal 18-14 Awg 5/16 Stud 100pk

Product Description

The THOMAS BETTS RB14-516 is a partially insulated, D-shaped ring terminal designed for crimp connections on 18 to 14 AWG copper conductors. The terminal features a copper contact with TiN (titanium nitride) plating for reliable conductivity and corrosion resistance. The nylon insulation sleeve is blue-coded for fast visual identification of the compatible wire gauge range. At 1.08 inches long and 0.47 inches wide, the RB14-516 accepts a 5/16 inch stud and is engineered for secure, high-cycle terminations in panel wiring, control circuits, and general electrical assembly work. Electricians and assembly technicians install these terminals using a ratchet crimp tool sized for the AWG range.

This ring terminal is suited for residential, commercial, and industrial electrical installations where a permanent, vibration-resistant ring lug termination is required. Typical applications include control panel wiring, HVAC low-voltage circuits, motor terminations, and equipment grounding connections. The partially insulated design allows the ring barrel to seat flush against a stud or lug without insulation interference. Sold in a package quantity of 100, the RB14-516 is appropriate for service contractors and panel shops that terminate wire in volume.

Compatibility

Designed as an OEM-style crimp ring terminal for use with 18 to 14 AWG stranded or solid copper conductors terminating on a 5/16 inch stud.

Installation Notes

Installation is performed by licensed electricians or qualified technicians in accordance with NEC guidelines for terminal connections. Always de-energize the circuit and verify zero voltage before installing or removing ring terminals. Use a calibrated ratchet crimp tool rated for the wire gauge and terminal series to ensure a proper crimp that meets UL pull-force requirements. Do not solder over a crimped connection, as this can create a stress point and compromise long-term joint integrity.
