Thomas Betts 71014 D-shaped Ring Terminal Crimp 2-4/0 Awg

Product Description

The THOMAS BETTS 71014 is a non-insulated, D-shaped ring terminal designed for crimp-style electrical connections in heavy-gauge wiring applications. Built with a copper contact, it accepts wire sizes from 2 AWG through 4/0 AWG and mounts to a 3/8 inch stud. The terminal measures 1.875 inches in overall length and 0.9375 inches in ring width, with a material thickness of 0.1875 inches. It carries UL Listed status under UL File E9809, CSA certification, and is RoHS compliant. Electricians and panel technicians use this terminal where a bare, compact ring lug is needed for bus bar, grounding, or heavy-load circuit terminations.

This terminal is suited for residential, commercial, and industrial electrical installations where large-conductor crimp terminations are required. Typical applications include main service panel grounding connections, equipment bonding, generator wiring, and heavy-gauge feeder runs. The D-shaped geometry provides additional contact surface area and mechanical retention at the stud mounting point compared to a standard round ring terminal. It is intended for use by licensed electricians performing work in accordance with applicable NEC guidelines.

Key Features

• Accepts 2 AWG through 4/0 AWG wire for large-conductor applications
• Crimp connection type for reliable, gas-tight electrical contact
• Non-insulated copper construction for direct conductor-to-lug contact
• 3/8 inch stud size fits common bus bar and grounding hardware
• UL Listed (File E9809), CSA Certified, and RoHS Compliant
• D-shaped ring geometry increases contact area at the mounting stud

Compatibility

Designed as a crimp-style ring terminal for use with 2 AWG through 4/0 AWG copper conductors on 3/8 inch mounting studs in standard electrical panel, grounding, and heavy-load wiring applications.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the circuit before terminating or removing any conductors. Use a ratchet-style crimping tool rated for the applicable AWG range to ensure a proper crimp that meets pull-force requirements. Do not solder over a crimped lug, as this can create stress concentration points and reduce long-term reliability.
