Burndy KA30U Type KA-U Aluminum Mechanical Lug, Dual-Rated CU/AL

Burndy KA30U Type KA-U Aluminum Mechanical Lug, Dual-Rated CU/AL

The Burndy KA30U is a Type KA-U universal terminal lug built from tin-plated aluminum alloy for reliable, code-compliant connections. This 1-hole mechanical lug is dual-rated for use with either copper or aluminum conductors, accepting 6 AWG to 350 kcmil stranded aluminum or copper conductors and 4 AWG to 4/0 AWG solid copper conductors. The electro tin-plated finish helps resist corrosion and supports a stable, low-resistance termination for panelboards, switchgear, and grounding applications. Because a single KA30U lug handles both conductor types, electrical contractors can standardize on one part number instead of stocking separate copper-only and aluminum-only terminals.

Key Features

• Wire Range: Accepts 6 AWG to 350 kcmil stranded aluminum/copper conductors and 4 AWG to 4/0 AWG solid copper conductors, giving installers broad application coverage from a single lug body.
• Durable Construction: Aluminum alloy body delivers a lightweight, corrosion-resistant mechanical lug built for demanding electrical environments and repeated field installation.
• Dual-Rated CU/AL: Type KA-U universal terminal is rated for both copper and aluminum conductors, reducing the need to stock separate copper-only and aluminum-only lug types on the truck or in the panel shop.
• 1-Hole Mounting Pad: Single-hole design allows straightforward mounting to busbars, ground bars, and equipment terminals with standard hardware.
• Finish: Electro tin-plated surface resists corrosion and helps maintain a stable, low-resistance connection over the life of the installation.
• Universal Terminal Design: The KA-U designation identifies this lug as part of Burndy's universal terminal family, engineered for flexible use across mixed copper/aluminum wiring systems.

Why Burndy?

Burndy engineers dual-rated connectors like the KA30U so electricians can carry one lug for both copper and aluminum conductor terminations instead of stocking two separate parts. The aluminum alloy body paired with an electro tin-plated finish is designed to resist corrosion and maintain a dependable, low-resistance connection across panelboard, switchgear, and grounding installations. The 1-hole mounting pad and wide 6 AWG to 350 kcmil stranded wire range make the KA30U a versatile choice for contractors who need a single terminal lug that fits multiple job requirements. For professionals who need code-compliant, dual-rated terminations backed by a trusted manufacturer name, the Burndy KA30U mechanical lug is built to perform.
