3M 7100069301 Aluminum One Hole Lug 1/0 Awg 35 Kv

Product Description

The 3M 7100069301 is a single-hole aluminum compression lug rated for use up to 35 kV in medium-voltage electrical applications. Sold as the Scotchlok 40032, it accepts 1/0 AWG conductors and is compatible with both copper and aluminum wire. The barrel measures 3.190 inches in length with a 0.414-inch inside diameter and is designed for a 3/8-inch stud. A contact aid pre-applied inside the barrel ensures reliable conductivity with poly and EPR insulation systems. Licensed electricians working on medium-voltage switchgear, transformer terminations, and cable assemblies will encounter this lug in commercial and industrial settings.

This lug is suited for medium-voltage cable terminations in commercial and industrial power distribution systems rated up to 35 kV. It accommodates 1/0 AWG copper or aluminum conductors, making it flexible across mixed-conductor installations. The tan color-coded end cap allows for quick visual identification during installation and inspection, reducing the chance of conductor size mix-ups on multi-phase or multi-circuit termination blocks.

Key Features

• Rated up to 35 kV for medium-voltage applications
• Accepts 1/0 AWG copper or aluminum conductors
• Pre-applied contact aid compatible with poly and EPR insulations
• Tan color-coded end cap for quick conductor size identification
• Single-hole mounting with 3/8-inch stud size
• Aluminum construction for corrosion resistance and weight savings

Compatibility

Designed for use with copper or aluminum 1/0 AWG conductors insulated with polyethylene or EPR compounds in medium-voltage cable termination assemblies up to 35 kV.

Installation Notes

Installation should be performed by a licensed electrician following applicable NEC and local code requirements for medium-voltage terminations. De-energize and verify the absence of voltage on all conductors before beginning work. Use the correct compression tool and die set specified for aluminum lugs of this size to ensure a proper mechanical and electrical connection. Do not over-torque the mounting stud beyond the hardware manufacturer's specified fastener rating.
