Blackburn AL4P – Frequently Asked Questions
1) What wire sizes does the Blackburn AL4P compression lug accept?
The AL4P takes #2 ACSR, and #1 to #2 stranded AWG conductors. It is a compression lug, so it is crimped onto the conductor rather than bolted, and each size range corresponds to a specific die. Conductors outside that range need a different lug in the series.
2) Will a two hole Blackburn AL4P lug line up with my busbar drilling?
The AL4P is a two hole long barrel lug drilled to NEMA standard mounting hole spacing, so it lands on busbar and equipment pads punched to NEMA pattern. Two hole mounting also stops the lug rotating under torque, which is why it is specified on switchgear and panel pads instead of a single hole tongue.
3) Can I use an aluminum Blackburn AL4P lug on copper conductors?
The AL4P body is aluminum with a tin plating. Tin plated aluminum lugs are the standard choice for aluminum conductors, and the tin plating is what allows contact with copper busbar or copper hardware without a direct aluminum to copper interface. Use it within the stated #1 to #2 stranded AWG and #2 ACSR range.
4) What does the LB in Blackburn AL4P mean, and when do I need a long barrel lug?
LB is long barrel. The longer crimp barrel takes more crimps along its length, which is what utility and substation specs call for on aluminum terminations where pull-out strength matters. If you only have room for a short barrel in a crowded panel gutter, a standard barrel lug of the same #1 to #2 stranded AWG range is the better pick.
5) Do I need a special crimp tool for the Blackburn AL4P?
Yes, it is a compression lug, not a mechanical set screw type, so it requires a hydraulic or battery crimp tool with the die matched to the #1 to #2 stranded AWG or #2 ACSR conductor being terminated. If you have no crimp tool on site, a mechanical aluminum lug is the alternative.
6) Is the Blackburn AL4P sold individually or in a bag of ten?
Each. The AL4P is sold as a single lug, so order one per termination and remember a two hole tongue needs two bolts, nuts and washers per lug, which are not part of the lug itself.
7) What is the manufacturer part number for the Blackburn tinned aluminum two hole long barrel lug?
AL4P is the Blackburn part number for the tin plated aluminum, two hole, long barrel compression lug rated for #1 to #2 stranded AWG and #2 ACSR. It is manufactured in Mexico.
