3M 7000031416 Aluminum One Hole Lug 35kv 3/0 Awg

Product Description

The 3M 7000031416 is an aluminum one-hole lug designed for terminating copper or aluminum conductors in medium-voltage electrical systems rated up to 35 kV. Sold individually, this lug features a 1/2-inch stud size, a 0.484-inch inner diameter, and an overall length of 3.440 inches. The barrel includes a factory-applied contact aid compatible with poly/EPR insulations, reducing the need for additional compound during installation. Color-coded end caps allow for quick conductor size identification on the job. Licensed electricians and utility line technicians working on medium-voltage distribution and termination assemblies are the primary installers.

This lug is suited for medium-voltage termination applications up to 35 kV. It is rated for 3/0 AWG conductors and accepts both copper and aluminum wire, making it a versatile choice for utility, industrial, and commercial electrical installations where mixed conductor types may be encountered. The ruby color coding on the end cap aids identification in multi-conductor termination work.
