Blackburn ALS4 – Frequently Asked Questions
1) What wire sizes does the Blackburn ALS4 compression lug take?
The ALS4 aluminum lug is rated for #2 ACSR and #1 to #2 stranded AWG conductor. If your run is larger or smaller than that range, you need a different lug body, since a compression barrel only makes a gas-tight connection on the conductor size it was sized and die-stamped for.
2) Will a two-hole lug like the Blackburn ALS4 line up with the bolt pattern on my busbar or equipment pad?
Yes, the ALS4 is a two-hole lug drilled to NEMA standard mounting hole spacing, which is the same pattern used on switchgear pads, ground bars, and busbar drilling. Two-hole termination also keeps the lug from rotating under fault current, which is why it is specified over single-hole on service equipment and grounding bars.
3) Is the Blackburn ALS4 a compression lug or a mechanical set-screw lug?
Compression. The ALS4 is crimped onto the conductor with a hydraulic or battery tool and the correct die, not tightened down with a set screw. That means you cannot install it with hand tools, and it is not re-usable once crimped, but it gives a permanent connection that is preferred where vibration or thermal cycling would loosen a mechanical lug.
4) Can I use the Blackburn ALS4 lug on copper conductor, or is it aluminum only?
The ALS4 is an aluminum-bodied compression lug. Aluminum bodies are commonly used dual-rated AL/CU, but the only conductor range on record for this part is #2 ACSR and #1 to #2 stranded AWG, so match the lug to the conductor size first and confirm the AL9CU marking stamped on the barrel before terminating copper.
5) What part number do I order for the Blackburn two-hole aluminum compression lug?
The manufacturer part number is ALS4, from Blackburn. It is an aluminum two-hole compression cable lug for #1 to #2 stranded and #2 ACSR conductor, made in Mexico.
6) Does the Blackburn ALS4 lug come as a single piece or in a bag of multiples?
It is sold each. The ALS4 is one two-hole aluminum compression lug per unit, so count your terminations, including grounds and neutrals, and order that quantity. Mounting bolts, washers, and nuts are not part of the lug.
