3M 7000031387 Copper One Hole Lug 6 Awg 35 Kv Blue

Product Description

The 3M 7000031387 is a copper one-hole lug rated for use on copper conductors only, designed for medium-voltage electrical connections up to 35 kV. Manufactured as a single-piece, seamless, high-conductivity copper lug, it features a 1/4 inch stud size, a 0.196 inch inside diameter, and a 1.780 inch body length. The blue color coding corresponds to its 6 AWG conductor range. This type of lug is installed by licensed electricians performing termination work on medium-voltage distribution systems, cable assemblies, and grounding applications where a reliable mechanical and electrical connection is required.

This lug is suited for medium-voltage applications up to 35 kV and is intended for use with 6 AWG copper conductors. It is commonly installed in commercial and industrial electrical systems where copper-to-copper terminations are required. The one-hole mounting configuration allows direct attachment to bus bars, switchgear lugs, and terminal blocks using a single fastener through the stud hole.

Key Features

• Rated for medium-voltage systems up to 35 kV
• One-piece seamless construction eliminates potential failure points at seams or joints
• High-conductivity copper material supports efficient current transfer
• Sized for 6 AWG copper conductors with a 0.196 inch inside diameter
• 1/4 inch stud size fits standard single-hole terminal mounting points
• Blue color coding for quick AWG identification during installation

Compatibility

Designed for use with 6 AWG copper conductors only in medium-voltage termination applications up to 35 kV. Not compatible with aluminum conductors.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize and lock out the circuit before making any terminations. Use the appropriate crimping tool specified for copper lugs of this conductor size to ensure a secure, gas-tight connection. Do not use on aluminum conductors.
