Blackburn AL 100 MMNTN 45 – Frequently Asked Questions
1) What conductor size does the Blackburn AL 100 MMNTN 45 aluminum lug take?
The AL 100 MMNTN 45 is sized for 100 mm2 conductor. It's a metric-sized aluminum compression lug, so it pairs with metric cable rather than AWG/kcmil sizing. If your cable is called out in AWG on the drawing, confirm the metric equivalent before you crimp, because a compression barrel is a one-shot install.
2) Is this a two-hole lug, and what is the pad size for bolting to a bus bar?
Two-hole pad, bent at 45 degrees. The pad measures 3.719 inches by 1.237 inches wide by .297 inch thick, the barrel is 1.938 inches, and the overall unbent length is 6.375 inches. Use the pad thickness when you're stacking washers and checking bolt length at the bus.
3) Does this lug meet a recognized connector standard for a spec job?
It is built to ANSI C119.4, the standard covering connectors for aluminum and copper conductors. That is the reference a submittal reviewer usually wants to see on a compression lug. Country of origin is the United States.
4) Can I use this aluminum lug on copper conductor?
The AL 100 MMNTN 45 is an aluminum-bodied compression lug that is tin plated. Tin plating on an aluminum body is what allows the pad to land on copper or aluminum bus without a dissimilar-metal problem at the bolted joint, and it slows oxidation on the pad face. The barrel itself is sized and rated for the conductor material the lug is built for, so match the barrel to the cable you're terminating.
5) What temperature is the Blackburn AL 100 MMNTN 45 rated for?
90 degrees C. That matches 90 C insulated conductor such as THHN/THWN-2 or XHHW-2, so the lug is not the limiting element in a 90 C rated termination. Ampacity on the circuit is still governed by whatever the terminal at the other end is rated for.
6) Does the lug come insulated, and do I need to add anything to finish the termination?
There is no insulation on it, so it is a bare compression lug. Plan on heat shrink or tape over the barrel where the installation calls for covered terminations, plus the bolts, washers and belleville hardware for the two-hole pad, none of which comes with the lug. It is sold each, not in a pack.
7) Can I crimp this lug with a standard hydraulic compression tool?
Yes, it's a compression lug with a 1.938 inch barrel, so it goes on with a hydraulic or battery crimper using the die the barrel calls for. It is not a mechanical set-screw lug, so there is no bolt to torque on the conductor end and it cannot be re-terminated once crimped.
8) What is the part number to order for the Blackburn 100 mm2 45 degree aluminum lug?
Order Blackburn AL 100 MMNTN 45. That is the manufacturer part number for the tin plated aluminum two-hole compression lug sized for 100 mm2 conductor, and it's sold as a single piece.
