Blackburn AL 750-48 TN – Frequently Asked Questions
1) What wire sizes does the Blackburn AL 750-48 TN compression lug accept?
The AL 750-48 TN takes 700 to 750 kcmil conductor, and is also rated for 636 (26/7) ACSR. If your cable is smaller than 700 kcmil, this barrel will not compress down onto it correctly, so step to the lug sized for that conductor instead.
2) Can I use this aluminum lug on copper conductor, or is it aluminum only?
The lug body is aluminum and it is tin plated, which is what makes it suitable for terminating either aluminum or copper conductor and for bolting to copper or aluminum pads without a dissimilar metal problem. It is a bare lug with no insulation, so any required cover or tape is a separate item.
3) Do I need a hydraulic crimper for the Blackburn AL 750-48 TN, or can it be set with a mechanical lug?
This is a compression lug, not a set screw or mechanical type, so it has to be crimped with the correct die for the barrel. If you want a connection you can make with a hex key and no crimp tooling, you need a mechanical (set screw) lug rated for 750 kcmil instead.
4) Is this lug rated for 90 degree C conductor like THHN or XHHW?
Rated to 90 C, so it matches the insulation rating of 90 C conductors. It is also built to ANSI C119.4, the standard for connectors used on electrical conductors, which is what inspectors and spec engineers look for on a utility or commercial feeder termination.
5) How many bolt holes does the Blackburn AL 750-48 TN have, and will it land on a two hole pad?
One hole. It bolts to a single stud or one hole in a pad. If your bus or transformer pad is drilled for two hole NEMA spacing and the spec calls for both bolts, you need a two hole 750 kcmil compression lug rather than this one.
6) Will a 750 kcmil compression lug fit inside my gear with limited space behind the pad?
Plan for a terminal 6-3/8 inches long by 1-3/4 inches wide. On 750 kcmil terminations in tight switchgear or a meter pedestal, that tongue length is usually the deciding factor, so measure from the bolt hole back to the cabinet wall before committing.
7) Are Blackburn AL 750-48 TN lugs made in the USA for a Buy American job?
Country of origin is the United States, which is what public works and federally funded projects with domestic sourcing language ask for on connectors.
8) Are these 750 kcmil lugs sold individually or in a bag?
Sold each, so you order one per termination. For a three phase plus neutral feeder that is four pieces, and most contractors add a spare since a miscrimped compression lug cannot be reused.
