Thomas Betts B14-4 Ring Terminal 18-14 Awg Crimp 100 Pack

Product Description

The THOMAS BETTS B14-4 is a non-insulated, D-shaped ring terminal designed for crimp-style wire terminations in electrical panel, control wiring, and equipment grounding applications. Rated for 18 to 14 AWG conductors and sized for a No. 4 stud, this terminal features a copper contact body with a TiN (titanium nitride) contact plating for reliable conductivity and corrosion resistance. At 0.72 inches in overall length and 0.25 inches in ring width, it fits into tight terminal blocks and enclosures without difficulty. Sold in a package of 100 units, this terminal is a standard stocking item for electricians and panel builders working on residential and light commercial wiring projects.

This terminal suits residential and commercial control panels, appliance wiring, HVAC low-voltage circuits, and general electrical equipment where a non-insulated ring lug is specified. The No. 4 stud size fits common small fasteners found on terminal strips, buss bars, and equipment grounding points. It is applicable where the installer will apply heat-shrink or sleeving separately, or where bare ring terminals are called for by the wiring diagram. The blue color coding assists in quick AWG-range identification on the bench or in the field.

Compatibility

Designed as an OEM-style crimp ring terminal for 18 to 14 AWG conductors requiring a No. 4 stud connection in electrical, HVAC control, and light commercial panel wiring applications.

Installation Notes

Installation is performed by a licensed electrician or qualified technician using a ratcheting crimp tool rated for the applicable AWG range. De-energize the circuit completely before terminating or replacing ring terminals and verify with a meter before contact. Follow NEC guidelines for conductor sizing, terminal torque, and wire fill. Do not use a terminal rated for 18 to 14 AWG with conductors outside that range, as an improper crimp will compromise the connection.
