Blackburn ALS10 – Frequently Asked Questions
1) What conductor size does the Blackburn ALS10 aluminum compression lug take?
The ALS10 is sized for 3/0 conductor, listed for both 3/0 ACSR and 3/0 stranded AWG. It is a one-size barrel, so it will not accept 4/0 or 2/0 cable. Match the conductor size exactly before crimping.
2) Is the ALS10 lug a compression crimp or a set screw mechanical lug?
Compression. The ALS10 is crimped onto the conductor with a die-type compression tool, not tightened with a set screw. If you need a connection you can install with a hex key and re-torque later, you want a mechanical set screw lug instead, not this one.
3) Can I use an aluminum compression lug on copper conductor?
The ALS10 body is aluminum and its cable range is given as 3/0 ACSR and 3/0 stranded AWG, so it is intended for aluminum conductor. For copper, use a copper or dual-rated AL9CU compression lug in the matching size rather than this one.
4) Will the two-hole pad on the ALS10 line up with the bus bar holes on my panel?
The ALS10 uses NEMA standard mounting holes on a two-hole pad, so it lands on bus and equipment pads drilled to NEMA spacing. Two-hole mounting also keeps the lug from rotating under fault current, which is why it is specified on switchgear and transformer pads instead of a single-hole tongue.
5) Should I use a two-hole lug or a one-hole lug on a 3/0 feeder termination?
For 3/0 landing on a bus or equipment pad, a two-hole lug like the ALS10 is the usual call: the second bolt resists the turning force a large conductor puts on the pad and stops the tongue from twisting. A one-hole lug is fine on smaller conductors and on pads that are only drilled for one bolt. Check what your pad is actually drilled for first, because a two-hole tongue will not mount on a single-hole pad.
6) Are mounting bolts and washers supplied with the Blackburn ALS10 lug?
No. The ALS10 is sold as a single lug, each, with nothing else in the pack. Plan on supplying your own pad bolts, washers, and belleville or lock hardware, plus a compression tool and the correct die for the crimp.
7) Can the ALS10 terminate ACSR overhead conductor, or only stranded building wire?
Both, at 3/0. The cable size covers 3/0 ACSR as well as 3/0 stranded AWG, so the same lug serves an overhead aluminum conductor steel reinforced run and a 3/0 stranded aluminum feeder.
8) How do I order the exact Blackburn 3/0 two-hole compression lug for a bid?
Order by manufacturer part number ALS10, Blackburn, an aluminum two-hole compression lug for 3/0. It is sold each, so quantity on the order equals number of terminations. Country of origin is Mexico if your submittal package asks for it.
