Thomas Betts ADR30 Square Ring Terminal 6 Awg

Product Description

The THOMAS BETTS ADR30 is a non-insulated square ring terminal designed for compression connections on 6 AWG copper or aluminum conductors. The terminal features an aluminum contact body with a titanium nitride (TiN) contact plating, which resists corrosion and helps maintain a stable electrical connection over time. At 2 inches in overall length and 1 inch in ring width, with a 5/16-inch stud size and 1/4-inch thickness, this terminal is built for solid, low-resistance terminations in electrical panels, junction boxes, and equipment grounding applications. Installation is straightforward using a standard compression tool sized for 6 AWG lugs.

This square ring terminal is suited for residential and commercial electrical work where a reliable, code-compliant lug connection is required. Electricians and panel technicians use it when terminating 6 AWG conductors to bus bars, ground lugs, or equipment terminals that accept a square ring style lug. The non-insulated design allows direct inspection of the compression joint after installation and is appropriate where sleeving or separate insulation is applied per local code requirements.

Key Features

• Non-insulated square ring design for 6 AWG conductors
• Compression connection method for secure, low-resistance termination
• Aluminum contact body with TiN (titanium nitride) plating for corrosion resistance
• 5/16-inch stud hole fits standard terminal studs and bus bar connections
• CSA Certified, UL Listed (UL File E9809), and RoHS Compliant

Compatibility

Designed as an OEM-style compression lug for 6 AWG conductor terminations requiring a square ring terminal with a 5/16-inch stud size.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements for lug terminations. De-energize the circuit and verify it is locked out before terminating any conductors. Use a compression tool rated for 6 AWG aluminum or copper lugs to achieve a proper crimp. Do not over-compress or use an incorrect die, as this can damage the barrel and reduce contact integrity.
