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.

Burndy KA30U – Frequently Asked Questions
1) Can the Burndy KA30U lug be used on aluminum conductors as well as copper?
Yes. The KA30U is a dual-rated CU/AL terminal, so the same lug body terminates either copper or aluminum conductors. That is the point of the Type KA-U universal terminal designation, and it lets a panel shop or service truck carry one part number instead of separate copper-only and aluminum-only lugs.
2) What wire sizes will the Burndy KA30U accept?
Stranded aluminum or copper from 6 AWG up to 350 kcmil, and solid copper from 4 AWG to 4/0 AWG. If your conductor is larger than 350 kcmil stranded, this lug body will not take it and you need a larger mechanical lug.
3) Is the KA30U a one-hole or two-hole lug?
One-hole. The KA30U has a single-hole mounting pad, which bolts to a busbar, ground bar, or equipment terminal with standard hardware. If your pad is drilled for two-hole NEMA spacing and you need the anti-rotation that gives, a 1-hole lug is the wrong choice there.
4) Is mounting hardware included with the Burndy KA30U mechanical lug?
No bolt, nut, or washer is supplied as part of the lug. The KA30U is the terminal body only, with a 1-hole pad sized for standard mounting hardware, so plan on supplying the bolt and hardware that matches the pad on your busbar or ground bar.
5) Will an aluminum-bodied lug hold up in a damp or corrosive panel location?
The KA30U body is aluminum alloy with an electro tin-plated finish. The plating is what resists corrosion and keeps the termination low-resistance over time, and it is also what makes the aluminum body acceptable against copper conductors rather than bare aluminum on copper.
6) Is the KA30U suitable for a grounding or bonding connection?
Yes, grounding and bonding is one of the stated uses, along with panelboards, switchgear, busbar and terminal block terminations, and general industrial or commercial wiring. The dual rating means you can land a copper grounding electrode conductor or an aluminum bonding jumper in the same lug type.
7) How do I order the right Burndy KA-U lug, and what is the exact part number?
Order by the Burndy part number KA30U, which is the single model in this Type KA-U configuration. Wire range and hole count are fixed by the part number, so the only thing you need to confirm is that your conductor falls inside 6 AWG to 350 kcmil stranded (or 4 AWG to 4/0 solid copper) and that your pad takes a 1-hole lug.
8) Mechanical lug or compression lug for a panelboard feeder termination?
A mechanical lug like the KA30U lands the conductor with a set screw, so it goes on with hand tools and can be backed out and re-terminated in the field. A compression lug needs a die and crimp tool and is not reusable. For panelboard, switchgear, and grounding work where conductors may change during a renovation, the mechanical type is the practical pick.
