Blackburn AL12 – Frequently Asked Questions
1) What wire size does the Blackburn AL12 compression lug take?
The AL12 is sized for 4/0 ACSR and 4/0 stranded AWG conductor. It is a single-conductor aluminum compression lug, so if your run is a different gauge you need a different die size lug, not this one.
2) Will the two-hole pad on the AL12 line up with a standard equipment bus bar?
Yes. The AL12 uses a two-hole tongue drilled to NEMA standard mounting hole spacing, so it bolts directly to panelboard, switchgear, and transformer pads drilled to the same NEMA pattern. The two-hole pad also resists rotation under fault, which single-hole lugs do not.
3) Do I need a crimp tool for the Blackburn AL12, or can it be bolted on?
It is a compression connector, not a mechanical set-screw lug. The barrel has to be crimped onto the conductor with a hydraulic compression tool and the correct die before the tongue is bolted to the pad. If you want a field termination with no crimper, you need a mechanical lug instead.
4) Are mounting bolts included with the Blackburn AL12 lug?
No hardware ships with the lug. The AL12 is the lug body only, with a two-hole NEMA-drilled tongue, so bolts, washers, and any Belleville hardware for the pad connection are ordered separately. Joint compound for the aluminum-to-pad interface is also a separate item.
5) Is the Blackburn AL12 sold individually or in a bag of multiples?
The AL12 sells as each, so on a three-phase-plus-neutral feeder termination you would order four, and count both ends of the run if you are lugging both.
6) What is the exact part number and manufacturer for this 4/0 two-hole aluminum lug?
Blackburn AL12 is the manufacturer part number, a two-hole aluminum compression lug for 4/0 conductor. Country of origin is Mexico.
