3M 7000031391 Copper One Hole Lug 35kv 2 Awg

Product Description

The 3M 7000031391 is a copper one-hole lug rated for use on systems up to 35 kV and sized for 2 AWG conductors. Built from one-piece, seamless, high-conductivity copper, this lug delivers reliable termination with minimal resistance at the connection point. It features a 3/8-inch stud size, a 0.307-inch inner diameter, and an overall length of 1.970 inches. Electricians and utility technicians use this lug for medium-voltage cable terminations where a secure, durable mechanical and electrical connection is required.

This lug is designed for copper conductors only and is suited for medium-voltage electrical applications up to 35 kV. Typical installations include switchgear, transformers, and panel terminations in commercial, industrial, and utility environments. The one-hole mounting configuration allows for straightforward bolt-down installation on standard equipment terminals and bus bars.

Key Features

• Rated for systems up to 35 kV
• Sized for 2 AWG copper conductors
• One-piece seamless construction for maximum conductivity and mechanical integrity
• High-conductivity copper material resists corrosion at termination points
• 3/8-inch stud size for standard hardware compatibility
• 1.970-inch overall length with 0.307-inch inner diameter

Compatibility

Designed for use with copper conductors only on medium-voltage systems rated up to 35 kV. Consult system specifications to confirm conductor size and stud size compatibility before installation.

Installation Notes

Installation should be performed by a licensed electrician qualified for medium-voltage work. De-energize and verify the absence of voltage on all conductors before beginning termination. Follow applicable NEC requirements for conductor termination at the rated voltage class. Use appropriate crimping or compression tooling as specified for the lug type and conductor size.
