Burndy KA29U Aluminum Set-Screw Terminal Lug

Burndy KA29U Aluminum Set-Screw Terminal Lug, Dual-Rated Al/Cu, 1-Hole

The Burndy KA29U is an aluminum universal set-screw terminal lug built for dual-rated Al/Cu conductor terminations in commercial, industrial, and utility electrical systems. This 1-hole mechanical lug accepts a wide conductor range of 6 AWG (Str) through 250 kcmil, mounts on a 5/16" stud, and is secured with a single set screw for a fast, dependable termination. Its aluminum body and electro tin-plated finish are designed to resist oxidation and corrosion, helping maintain a stable, low-resistance connection over the life of the installation. As a universal terminal, the KA29U is suited for panelboards, switchgear, grounding systems, and other equipment terminations where flexible conductor sizing and dual-metal compatibility are required.

Key Features

• Wide Conductor Range: Accepts 6 AWG (Str) through 250 kcmil conductors, giving installers flexibility to terminate a broad range of wire sizes with a single lug.
• Aluminum Construction: An aluminum lug body provides a lightweight, corrosion-resistant terminal suited to demanding electrical environments.
• 1-Hole, 1-Screw Mounting: Single-hole pad with one set screw delivers a fast, secure mechanical termination without specialized crimping tools.
• 5/16" Mounting Stud: Sized for standard 5/16" hardware, simplifying installation on busbars, panels, and equipment pads.
• Dual Rated Al/Cu: Rated for use with both aluminum and copper conductors, so the same lug can be specified across mixed-conductor jobs, reducing the number of part numbers electricians and distributors need to stock.
• Electro Tin Plated Finish: The tin-plated surface helps reduce oxidation at the connection point and supports a stable, low-resistance electrical contact over time.
• Universal Terminal Design: A general-purpose mechanical lug configuration intended for a broad range of termination applications rather than a single equipment type.

Technical Specifications

• Conductor Range: 6-AWG.
• Plating: Electro Tin Plated.

Typical Applications

• Panelboard and Switchgear Connections
• Grounding and Bonding Terminations
• Motor Control Center Wiring
• Industrial and Commercial Electrical Installations
• Utility and Equipment Terminations
• Renovation and New Construction Projects

Why Burndy?

Burndy mechanical lugs like the KA29U are engineered for dependable, code-compliant electrical terminations where installers need flexibility across conductor types and sizes. The dual-rated Al/Cu aluminum construction, 1-hole set-screw mounting, and electro tin-plated finish work together to deliver a durable, low-resistance connection built for demanding commercial, industrial, and utility electrical work. Specifying a dual-rated universal terminal like the KA29U also helps simplify inventory for contractors and distributors who need one lug to cover both aluminum and copper conductor jobs.
