3M 7000038685 Copper Two Hole Long Barrel Lug 2/0 Awg

Product Description

The 3M 7000038685 is a copper two-hole long-barrel lug designed for terminating copper conductors in medium-voltage electrical systems rated up to 35 kV. Constructed from one-piece, seamless, high-conductivity copper, this lug delivers reliable electrical continuity and mechanical strength at the termination point. It accepts 2/0 AWG copper conductors and features a 0.44-inch inner diameter, a 0.5-inch stud size, and an overall barrel length of 5.0 inches. The two-hole mounting configuration provides a secure, low-resistance connection at switchgear, transformers, and bus bar terminations. Licensed electricians and high-voltage cable splicers are the typical installers.

This lug is suited for medium-voltage power distribution applications in both commercial and industrial settings. The long-barrel design accommodates deeper conductor insertion, improving current-carrying capacity and pull-out resistance. It is intended strictly for use with copper conductors and is appropriate for switchgear terminations, transformer secondaries, and similar high-current connection points where a two-hole mechanical bond is specified.

Key Features

• One-piece seamless construction eliminates joints that can introduce resistance or failure points
• High-conductivity copper material rated for use up to 35 kV
• Long-barrel design supports deeper conductor seating for improved mechanical retention
• Two-hole mounting pattern distributes clamping load and resists lug rotation
• 0.44-inch inner diameter sized for 2/0 AWG copper conductors
• 0.5-inch stud size for standard medium-voltage hardware compatibility

Compatibility

Designed for use with copper conductors only at 2/0 AWG. Rated for medium-voltage systems up to 35 kV. Compatible hardware details, specific switchgear models, or additional system families were not specified in the available product data.

Installation Notes

Installation should be performed by a licensed electrician or qualified high-voltage cable splicer following applicable NEC and local code requirements. De-energize and lock out the circuit before beginning any termination work. Use manufacturer-specified compression tooling appropriate for the lug barrel dimensions to ensure a proper crimp. Do not use this lug on aluminum conductors.
