Blackburn LAC12 AL SLOTTED COMP TERM No1 WHT 2SLOT

The LAC12 aluminum compression terminal lug is sized for #1 stranded or 1/0 solid conductor. It's a one-conductor, die-crimped lug, so the conductor has to match that range for the crimp to hold; oversized or undersized wire in a compression barrel is the most common cause of a failed termination.

The LAC12 is an aluminum-bodied compression lug. Aluminum barrels are normally installed on aluminum conductor unless the lug carries a dual-rated AL9CU marking, so if your feeder is copper, buy a lug marked for copper rather than assuming this one crosses over.

Two slots in the tang, not a single round hole. The slotted two-hole tang lets the lug land on a bus or breaker pad with two-bolt spacing and gives some play to line up with the existing drilling instead of forcing an exact center-to-center match.

600 V, with a 90 degree C temperature rating. That covers standard building feeder and branch work using 90 C insulated conductor such as THHN or XHHW, and panel, transformer, and switchgear terminations at 600 V or less.

No insulation on this one. The LAC12 ships bare with no sleeve or boot, so on any live termination you finish it yourself with heat shrink or tape per your spec. If you want a factory-insulated barrel, order an insulated lug instead.

A compression lug is crimped once with a matched die and stays put, which is why it's specified where vibration or repeat thermal cycling would loosen a set screw, and it needs no re-torque check. A mechanical set-screw lug is the choice when you have no crimp tool on site, when the conductor size may change later, or when you need to break the connection and remake it. The LAC12 is the compression type, so plan on having the correct tool and die at the panel.

White is the color code Blackburn uses to identify the die and conductor range on this compression lug, so the installer and the inspector can confirm the right die was used from the crimp color rather than measuring the barrel. Match the die to the white code when you crimp it.

Order it as Blackburn LAC12. It is manufactured in Mexico, which is the detail institutional and government buyers usually need for country-of-origin documentation on a submittal.
