ABB A-Series Oversized Pressure Main Lug Kit, Unassembled
The ABB A-Series Oversized Pressure Main Lug Kit is a Pro-Stock, unassembled main lug kit engineered for ABB A-Series™ lighting panelboards. Featuring oversized, pressure-type lugs suitable for interiors wired with either copper or aluminum bus, this kit gives panel builders flexible termination options for larger feeder conductors on lighting panel installations. Supplied unassembled and packaged 1 EA, it pairs directly with A-Series lighting panelboard assemblies for professional electrical installations that require dependable main lug hardware sized above standard offerings.
Key Features
- Lug Type: Pressure-type lugs provide a secure, mechanical conductor termination at the main lug position, supporting solid and stranded conductor terminations.
- Oversized Sizing: Oversized lug construction accommodates larger conductor terminations than a standard main lug kit, useful where feeder conductors exceed typical panelboard lug capacity.
- Bus Compatibility: Lugs are suitable for interiors wired with either copper or aluminum bus, supporting flexible wiring methods across job sites.
- Pro-Stock Configuration: Supplied unassembled as a Pro-Stock kit, allowing installers to field-fit the main lug assembly to the A-Series™ lighting panelboard.
- Panelboard Platform: Designed specifically for use with ABB A-Series™ lighting panelboard lines, keeping lug hardware matched to the panelboard family.
- Packaging: Supplied 1 EA per kit for straightforward stocking, inventory planning, and installation scheduling.

ABB MLA2 – Frequently Asked Questions
1) Will the ABB MLA2 main lug kit work on any panelboard, or only A-Series?
The MLA2 oversized pressure main lug kit is built for ABB A-Series lighting panelboards. It is matched to that panelboard platform, so it is not a general purpose lug kit for other panel families. If your interior is not an A-Series lighting panelboard, this is the wrong part.
2) Can I use these lugs with aluminum feeder conductors, or is it copper only?
Either. The oversized pressure lugs in the MLA2 kit are suitable for interiors wired with copper or aluminum bus, which is why panel builders keep one kit on the shelf for both wiring methods. Pressure-type terminations also take solid or stranded conductors.
3) Why choose an oversized main lug kit instead of the standard one?
Oversized lugs exist for the case where the feeder conductors coming into the panel are larger than the standard main lug position will accept. If your feeder sizing is within the panelboard's typical lug capacity, a standard main lug kit does the job. Go oversized when the conductor size being terminated exceeds it.
4) Does the ABB MLA2 lug kit come assembled and ready to drop in?
No. It ships unassembled as a Pro-Stock kit, so the installer field-fits the main lug assembly to the A-Series panelboard. Budget bench or field time for assembly rather than planning on a bolt-in swap.
5) Is a main lug kit the same thing as a main breaker for a panelboard?
No, and the difference matters for how the panel is fed. A main lug kit terminates the incoming feeder conductors directly onto the bus with no overcurrent device at the panel itself, so the upstream breaker protects the panel. A main breaker interior gives you disconnect and overcurrent protection at the panel. The MLA2 is a main lug kit with pressure-type lugs, intended for main lug only A-Series lighting panel builds.
6) What is the ABB part number for the oversized A-Series main lug kit?
Order it as MLA2. That is the ABB manufacturer part number for the A-Series oversized pressure main lug kit, unassembled, and it is the number to quote when matching lug hardware to an existing A-Series lighting panelboard order.
7) Can I use this kit to upgrade an existing A-Series lighting panel to larger feeders?
That is one of its intended uses. Panelboard wiring upgrades and panel retrofit work are listed applications, and the oversized pressure lugs are what let you land feeder conductors that the original standard-size main lugs would not accept. The kit is unassembled, so the lug assembly is fitted to the existing A-Series interior on site.
8) How many lug kits come in an ABB MLA2 order?
Packaging is 1 EA per kit. One order line gets you one main lug kit, which makes stocking and job scheduling straightforward if you are outfitting several panels and need a count that matches panel-for-panel.
