Thomas Betts L250P D-shaped Ring Terminal 6 Awg Lug

Product Description

The THOMAS BETTS L250P is a non-insulated, D-shaped ring terminal designed for secure lug-style wire terminations in electrical installations. Built with a copper contact and a titanium nitride (TiN) plating, it delivers reliable conductivity and corrosion resistance at the connection point. The terminal accepts 6 AWG wire and fits a 13/32-inch stud. Overall dimensions are 1-61/64 inches long and 15/16 inches wide, with a body thickness of 1/8 inch. Electricians and panel technicians use this terminal when making permanent, code-compliant connections in control panels, motor circuits, and power distribution assemblies.

This terminal is suited for residential and commercial electrical work where a bare, non-insulated ring lug is required at a bolted stud connection. Typical applications include grounding conductors, panel feeders, motor lead terminations, and equipment bonding points. The D-shaped ring geometry prevents the terminal from rotating on the stud once torqued, which is useful in vibration-prone environments such as mechanical rooms and rooftop equipment installations. It is sold as a single piece, making it practical for service and retrofit work where only one termination point needs replacement.

Key Features

• D-shaped ring design resists rotation on the stud after fastening
• Copper contact with TiN plating for conductivity and corrosion resistance
• Accepts 6 AWG wire via lug-style compression connection
• Fits 13/32-inch stud diameter
• Non-insulated construction for applications where sleeve insulation is added separately or not required
• CSA Certified, RoHS Compliant, and listed under UL 486A (UL File E9809)

Compatibility

Designed as an OEM-style replacement or new-installation ring terminal for 6 AWG conductors terminated at 13/32-inch lug-style stud connections in electrical panels, motor circuits, and bonding applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements for wire terminations and equipment grounding. De-energize and lock out the circuit before crimping or fastening this terminal. Use a calibrated crimping tool rated for 6 AWG non-insulated lugs to ensure a proper mechanical and electrical connection. Do not over-tighten the stud fastener, as deformation of the ring can compromise contact integrity.
