3M 7000031396 Copper One Hole Lug 2/0 Awg 35 Kv

Product Description

The 3M 7000031396 is a copper one-hole lug designed for terminating copper conductors in high-voltage electrical applications up to 35 kV. Constructed from one-piece, seamless, high-conductivity copper, it provides a reliable, low-resistance connection at the termination point. The lug features a 3/8-inch stud size, a 0.439-inch inner diameter, and a 2.370-inch body length. It is sized for 2/0 AWG conductors. Licensed electricians and electrical contractors install this lug in medium-voltage cable assemblies, switchgear, and distribution equipment where a secure, corrosion-resistant copper-to-copper termination is required.

This lug is suited for medium-voltage residential and commercial electrical installations where conductor terminations must be made up to 35 kV. It is sold individually and is intended for use exclusively on copper conductors. Typical applications include transformer terminations, switchgear connections, and cable tray work in industrial and utility environments where a single-hole mounting configuration is required.

Key Features

• One-piece, seamless construction eliminates weak points and reduces resistance at the termination
• High-conductivity copper material rated for copper conductors only
• Rated up to 35 kV for medium-voltage applications
• 3/8-inch stud size with 0.439-inch inner diameter for 2/0 AWG conductors
• 2.370-inch body length provides adequate contact area for secure crimping
• Single-hole mounting configuration for straightforward panel and switchgear attachment

Compatibility

Designed for use with copper conductors only at 2/0 AWG, rated for systems up to 35 kV. Intended as an OEM-style termination lug for medium-voltage electrical assemblies requiring a single-hole lug configuration.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements and local codes. De-energize and lock out the circuit before installing or removing any termination lug. Use the appropriate crimping tool specified for the conductor size and lug type to achieve a proper, gas-tight crimp. Do not use this lug on aluminum conductors.
