Blackburn LAC4 – Frequently Asked Questions
1) What wire size does the Blackburn LAC4 compression lug take?
The LAC4 is sized for #4 AWG stranded or #3 AWG solid conductor. Orange is the color-coded die marking on this one, so you match the orange die in your compression tool to the lug barrel. Run it on anything smaller and the crimp will not hold; step to the next size lug for #2 or #6 conductor.
2) Is the LAC4 rated for use with 90 C THHN in a 600 V panel?
Yes. The lug carries a 600 V rating and a 90 C temperature rating, which covers standard building wire in branch panels, disconnects, and meter sockets at that voltage class.
3) Do I need a special crimp tool for the Blackburn LAC4, or can I bolt it on?
It is a compression connector, not a mechanical set-screw lug, so it has to be crimped with a hydraulic or battery compression tool using the correct die. There is no screw to torque. If you want a lug you can install with a hex key and no tool investment, you need a mechanical screw-type terminal lug instead.
4) Can I use an aluminum lug like the LAC4 on copper conductor?
The LAC4 is an aluminum-bodied compression terminal lug, bare, with no insulation. Aluminum bodies are generally listed AL9CU for both aluminum and copper conductor, but that dual rating is not something to assume from the catalog data alone. What is on record here: aluminum body, bare finish, #4 stranded / #3 solid AWG, 600 V, 90 C. Confirm the AL9CU marking stamped on the lug itself before putting it on copper.
5) What does slotted tang mean on a compression terminal lug, and will it fit my lug pad?
Slotted tang means the flat mounting palm has an open slot rather than a closed round hole, so you can slide the lug under a partially backed-off bolt instead of removing the hardware and threading it through. That is the reason electricians pick a slotted tang for crowded gear and busbar pads. The slot width and bolt hole spacing are not on record here, so check the tang against your pad bolt size before you crimp.
6) Does the LAC4 come insulated or with a heat shrink sleeve?
No insulation, bare aluminum. If the termination is in a location that needs the barrel covered, you add adhesive-lined heat shrink or an insulating boot separately. The bare finish also means you should apply the appropriate joint compound where your gear or the AHJ calls for it on aluminum terminations.
7) For an MRO buyer standardizing panel terminations, where does the LAC4 sit in the Blackburn lug range?
The LAC4 is the #4 stranded / #3 solid position in Blackburn's aluminum slotted-tang compression lug family, orange die code, 600 V, 90 C. Because the family runs by conductor size with the same tang style and die-color system, you can standardize the whole facility on one tool and die set and stock only the sizes your feeders and branch circuits actually use.
8) Where is the Blackburn LAC4 made?
Mexico. That matters on public and institutional work where country of origin has to be documented in the submittal package.
