Thomas Betts B14-38 Ring Terminal 18-14 Awg 3/8 Stud

Product Description

The THOMAS BETTS B14-38 is a non-insulated, D-shaped ring terminal designed for crimp connections on copper conductors ranging from 18 to 14 AWG. The contact is copper with a TiN (titanium nitride) plating for reliable conductivity and corrosion resistance. At 0.96 inches long and 0.54 inches wide, this terminal accommodates a 3/8-inch stud. It is used in control wiring, panel builds, and equipment terminations where a secure, compact ring lug is required. Electricians and panel technicians install this terminal using a ratcheting crimp tool sized for the applicable AWG range. The package quantity is 100 units per order.

This terminal is suited for residential and light commercial electrical panels, HVAC control wiring, and industrial equipment terminations where a 3/8-inch stud size and 18-to-14 AWG wire range are specified. The non-insulated design is appropriate for applications where insulation will be provided by the enclosure or where the installer applies separate sleeving per code requirements. It is commonly used by licensed electricians and controls technicians working on low-voltage and line-voltage panel assemblies.

• Copper contact with TiN plating for conductivity and corrosion resistance
• Non-insulated barrel — compatible with standard open-barrel crimp tooling
• UL Listed under UL 486A and UL 486B; CSA Certified; RoHS Compliant
• UL 94 V-0 rated; sold in a package quantity of 100

Compatibility

Designed for use with 18 to 14 AWG copper conductors and 3/8-inch mounting studs in control panels, terminal blocks, and equipment lugs requiring a non-insulated ring terminal with a crimp connection style.

Installation Notes

Installation should be performed by a qualified electrician in accordance with NEC requirements and any applicable local codes. De-energize the circuit completely before terminating or inspecting ring terminals. Use a calibrated ratcheting crimp tool rated for the conductor AWG and terminal series to ensure a gas-tight crimp. Do not solder over a crimped connection on these terminals, as this can compromise the mechanical integrity of the crimp.
