ABB MLA1 – Frequently Asked Questions
1) Will the ABB MLA1 main lug kit work on a panel interior with aluminum bus, or is it copper only?
Either one. The MLA1 main lug kit is suitable for A-Series interiors with copper bus or aluminum bus, so you do not have to sort your panel stock by bus material before pulling a lug kit off the shelf.
2) What panels does the ABB MLA1 lug kit actually fit?
It is built for ABB A-Series panelboards and Pro-Stock unassembled lighting panels. It is not a universal lug, so if your interior is another manufacturer's panel or a different ABB family, the MLA1 is the wrong kit.
3) Is this a mechanical pressure lug or a compression lug?
Pressure type. The MLA1 uses a pressure-style main lug that terminates the conductor under a set screw, so it is a field termination with hand tools, no crimp die or hydraulic tool needed.
4) Does the ABB MLA1 kit come assembled in the panel or do I install it in the field?
Field install. The MLA1 is a standard main lug kit supplied unassembled, intended to be fitted to a Pro-Stock unassembled lighting panel or A-Series interior on the job. That is the point of the Pro-Stock program: stock the bare interiors and add the main device or lug kit when the job calls for it.
5) I need a main lug only panel instead of a main breaker. Is this the part that converts it?
The MLA1 is the main lug kit for that build, yes. On an A-Series or Pro-Stock unassembled lighting panel you add either a main breaker or a main lug kit, and the MLA1 is the standard pressure lug option where the feeder is protected upstream and the panel only needs a termination point at the bus.
6) How many lug kits come in a package of ABB MLA1?
One kit per package, sold 1 EA. If you are assembling several Pro-Stock lighting panels on the same job, order one MLA1 per interior rather than expecting a multi-pack.
7) Is the ABB MLA1 main lug kit made in the USA?
Country of origin is the United States, which matters if you are bidding public or federally funded work with domestic sourcing language in the spec.
