Blackburn AL 1000 NCPTN AL COMP LUG 1000 2HOLE TINPL COMPND

The AL 1000 NCPTN is sized for 1000 kcmil conductor. It's a one-size lug, not a range, so a 750 or 1250 kcmil cable needs a different die and barrel. Crimp it with the die series your tool maker calls for on 1000 kcmil aluminum compression barrels.

It's a tin plated aluminum body, and tin plated aluminum compression lugs of this type are the standard dual-rated choice for terminating either aluminum or copper cable, which is why the plating is there. The barrel comes factory filled with oxide inhibiting compound for the aluminum termination. Confirm the AL9CU style dual rating marking on the lug body against your spec if the drawing calls it out explicitly.

Two hole tongues are meant for NEMA standard pad drilling, which puts the holes on a fixed center to center spacing with a matching bolt size. The overall lug measures 8.562 inches long by 1.750 inches wide, so the tongue width is what you check against the width of your bus pad. Two holes stop the lug rotating under fault torque, which is why utility and switchgear specs call for them over single hole.

Rated to 90 degrees C, which matches THHN/THWN-2 and XHHW-2 cable insulation run at the 90 degree column. It's built to ANSI C119.4, the standard covering connectors for aluminum and copper conductors, so it satisfies specs that name that document. Made in the United States.

No. The barrel ships pre-filled with inhibitor compound and sealed, so you strip the conductor, seat it fully, and crimp. Don't wire brush the compound out. If the seal is broken in the box, check that the compound is still present before you use it.

Bare metal, no insulation on the barrel or tongue. On anything exposed or where you need phase identification, plan on a heat shrink boot, phase tape, or a molded cover sized for a 1000 kcmil aluminum barrel, ordered separately.

This one is compression, meaning it's crimped with a hydraulic tool and the correct die, and it's permanent. Compression is what large feeder and switchgear specs generally require because it gives a consistent, torque-independent connection with no set screw to re-torque. A mechanical lug is the option when you have no crimp tool on site or need to be able to break the termination down later, but it costs you the inspection advantage and needs periodic re-torque.

Sold each. The part number to order is AL 1000 NCPTN. Count one per conductor termination, so a three phase plus neutral feeder run needs four per end, eight for both ends.
