Blackburn LAC25 – Frequently Asked Questions
1) What wire size does the Blackburn LAC25 compression lug take?
The LAC25 is sized for 350 kcmil conductor, and the range marked on it also covers 266.6 kcmil and 250 kcmil. It is an aluminum-bodied compression terminal lug, so it is crimped onto the conductor with a die tool rather than bolted or set-screwed.
2) How many bolt holes does the LAC25 lug tang have?
Two. The LAC25 is a slotted-tang compression terminal lug with a 2-slot pad, so it lands on a two-hole bus or breaker pad. If your equipment pad is drilled for a single bolt, you want a one-hole lug instead.
3) Can I use an aluminum Blackburn LAC25 lug on a copper conductor?
The LAC25 body is aluminum and the barrel is sized for 350 kcmil. Aluminum compression lugs of this style are commonly dual-rated AL9CU, but that marking is not part of the data carried here, so go by the rating stamped on the lug body and the die chart before crimping copper into it.
4) What voltage and temperature is the Blackburn LAC25 terminal lug rated for?
600 V, with a 90 degrees C conductor temperature rating. That puts it in line with standard THHN/THWN-2 and XHHW-2 feeder work at 90 degrees C ampacity in ordinary building distribution gear.
5) Is the LAC25 lug insulated, and do I need to cover it after crimping?
There is no insulation on it. The LAC25 ships bare aluminum with no sleeve or boot, so any required covering at the termination, heat shrink, tape, or an insulating boot, is a separate item you add on the job.
6) What does the green color on the Blackburn LAC25 lug mean?
Green is the die-code color for this barrel size. Compression lugs are color coded so the crimper operator can match the connector to the correct die in the tool set; on the LAC25 that green band corresponds to the 350 kcmil barrel. Match the green die in your crimp tool, not just the conductor size.
7) Is the Blackburn LAC25 sold individually or in a box?
Each. The LAC25 is sold as a single lug, so order the count you need for the terminations on the job, remembering a three-phase-plus-neutral feeder end takes four.
8) Where is the Blackburn LAC25 lug made?
United States. For public or federally funded work with domestic-sourcing language in the spec, US origin on connectors like the LAC25 is usually the item the submittal reviewer flags.
