Blackburn AL 400-48 ALUM COMP LUG 400 KCMIL 2 HOLE

The AL 400-48 aluminum compression lug is sized for 400 kcmil conductor, and also covers 397.5 kcmil (a common ACSR/AAC overhead size). If your feeder is 350 or 500 kcmil, this is the wrong barrel, go to the lug built for that size.

The part description calls it a 2-hole lug, meaning two bolt holes on the tongue for a two-bolt pad. Our internal type classification reads one-hole, so the two records disagree. Order to the description only if your pad is drilled for two bolts, and verify the tongue drilling before you land it on a single-bolt bus.

It is built to ANSI C119.4, the standard covering connectors for aluminum and copper conductors. That is the citation to put on a submittal when a utility or facility spec calls for a C119.4 compression connector.

Compression only. The barrel is crimped onto the conductor with a hydraulic compression tool and the correct die, so there is no set screw to torque. If your crew does not have a 400 kcmil-capable compression head on site, a mechanical set-screw lug is the easier call for that termination.

It is an aluminum-body compression lug. Aluminum connectors of this style are commonly listed AL9CU for both aluminum and copper, but that dual rating is not something to assume on a given part number, so treat the AL 400-48 as an aluminum-conductor lug unless the marking on the barrel says otherwise. Check the stamp on the part before you crimp copper into it.

Overall length is 4-7/8 inches. That is the number to work with when you are checking bending space and barrel clearance in a tight switchgear cabinet or a wireway before the conductor is cut.

Country of origin is the United States, which is what a government, school district, or federally funded job needs on record for a Buy American or BABA submittal.

Sold each, one lug per unit, so you order the exact count of terminations. Remember to count both ends of every feeder run plus spares for miscrimps.
