Blackburn ALS28 – Frequently Asked Questions
1) What conductor size does the Blackburn ALS28 compression lug take?
The ALS28 is sized for 477 kcmil ACSR in both the 30/7 and 26/7 strandings. It is a one-size compression lug, so it has to be crimped onto a conductor in that range. Put it on a smaller or larger conductor and the crimp will not hold.
2) Is the Blackburn ALS28 a bolt-on lug or does it need a crimp tool?
It's a compression lug. The barrel has to be crimped onto the conductor with the proper die set and hydraulic tool, not tightened with a set screw. If you want a lug you can land with an Allen key in the field, you need a mechanical set-screw lug instead.
3) Will the Blackburn ALS28 bolt to a standard two-hole pad on a transformer or switchgear?
Yes. The ALS28 is a two-hole tongue drilled to NEMA standard mounting hole spacing, so it lands on any NEMA-drilled bus pad or equipment terminal pad without redrilling.
4) Can I use the aluminum ALS28 lug on a copper bus bar or a copper conductor?
The ALS28 body is aluminum and it's rated for 477 kcmil ACSR conductor, so the crimp end is for aluminum cable, not copper. Bolting an aluminum tongue to a copper pad is a dissimilar-metal joint, so use the proper antioxidant compound and hardware for that connection, or pick a copper or bimetallic lug if the run is copper.
5) Is the Blackburn ALS28 suitable for ACSR overhead conductor, or only all-aluminum cable?
It's specified for ACSR, the steel-reinforced aluminum conductor, in 477 kcmil at 30/7 and 26/7 stranding. Those are the two strandings it's die-matched to, so confirm the stranding on your reel before crimping.
6) Does the Blackburn ALS28 come as a single lug or in a pair?
It's sold each. A terminated conductor needs one lug per end you're landing, so for a three-phase set plus neutral you'd order four, and both ends of a run doubles that.
7) What is the overall length of the Blackburn ALS28 lug?
6-7/8 inches overall. That's worth checking against the space in your cabinet or termination compartment, since a two-hole aluminum lug of that length needs bending room for the conductor behind the pad.
