Thomas Betts ADR60 Square Ring Terminal 2 Awg Aluminum

Product Description

The THOMAS BETTS ADR60 is a non-insulated square ring terminal designed for use with 2 AWG aluminum conductors. It provides a secure, low-resistance mechanical connection between a conductor and a threaded stud or bolt. The contact is made from aluminum with a TiN (titanium nitride) plating for improved corrosion resistance and conductivity at the connection point. Measuring 3.1875 inches long and 1.5 inches wide, with a 0.4375-inch thickness, this terminal is built for permanent termination work in electrical panels, distribution equipment, and heavy-gauge wiring applications. Installation is performed by licensed electricians.

This terminal is suited for aluminum conductor terminations in residential and commercial electrical installations where 2 AWG wire is routed to a 3/8-inch stud connection. Common applications include service entrance wiring, load center lugs, and bus bar connections. The AL9CU marking indicates suitability for use with both aluminum and copper conductors at the rated connection point, making it a practical choice across a range of panel and switchgear termination scenarios.

Compatibility

Designed for use with 2 AWG conductors and 3/8-inch threaded studs. AL9CU rating confirms suitability for both aluminum and copper conductor terminations per applicable wiring standards.

Installation Notes

Installation should be performed by a qualified, licensed electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize and lock out the circuit before terminating or inspecting connections. Use a calibrated torque wrench and follow the stud manufacturer's torque specifications for the 3/8-inch fastener. Do not over-crimp or under-crimp the barrel, as improper termination can cause elevated contact resistance and heat buildup.
