Burndy K-Series 2-Conductor Aluminum Universal Terminal Lug, Dual Rated AL/CU

Burndy Aluminum Universal 2-Conductor Terminal Lug, 1-Hole

The Burndy Aluminum Universal 2-Conductor Terminal Lug, 1-Hole is a mechanical connector engineered to terminate aluminum and copper conductors onto equipment pads, bus bars, and grounding systems. Rated for 6 AWG (Str) through 250 kcmil conductors, this Al/Cu rated lug features a single 3/8" mounting stud and two conductor barrels secured by independent screws, giving installers the flexibility to land two conductors from one compact, single-hole terminal. The aluminum body and tin-plated finish are designed to resist corrosion and help maintain low-resistance electrical contact in demanding commercial and industrial environments where both aluminum and copper wiring may be present.

Key Features

• Stud Size: 3/8" mounting stud for secure attachment to equipment pads, bus bars, and ground connections.
• Conductor Range: Accepts 6 AWG (Str) through 250 kcmil conductors, covering a wide span of wire sizes with a single part number and simplifying stocking for electrical contractors.
• 2-Conductor, 1-Hole Design: Single-hole mounting terminal with two independent conductor barrels, allowing two conductors to land on one lug where the equipment provides only one mounting hole.
• Durable Construction: Aluminum body construction that is Al/Cu rated for use with both aluminum and copper conductors, reducing the need for separate aluminum-only and copper-only inventory.
• Dual Screw Termination: Two screws independently secure each conductor barrel, giving installers a dependable, code-compliant mechanical connection for each conductor.
• Finish: Tin-plated (electro tin plated) surface improves corrosion resistance and helps maintain consistent conductivity at the connection point over the life of the installation.
• Universal Rating: Al/Cu dual-rated design lets this single terminal lug serve mixed-metal jobsites without swapping part numbers between aluminum and copper runs.
