Blackburn LAC402 – Frequently Asked Questions
1) What wire size does the Blackburn LAC402 compression lug take?
The LAC402 is sized for 4/0 AWG conductor, stranded as well as compressed and compact 4/0. It is an aluminum-bodied compression lug, so it terminates aluminum or copper 4/0 cable in a single crimp barrel. If your cable is 250 kcmil or 2/0, this is the wrong lug and you need the size-matched part instead.
2) What does the pink color code on this 4/0 compression lug mean for crimping?
Pink is the die color code for the LAC402's crimp. Set your hydraulic or battery compression tool to the pink-coded die matching the barrel and make the number of crimps the barrel length calls for. The lug itself is pink-marked; the body is bare aluminum with no insulation or plating over it.
3) How many bolt holes does the Blackburn LAC402 tang have, and will it land on a two-hole pad?
Two slots on the tang, so it lands on a two-hole bus pad or breaker lug pad. The slotted tang gives you some lateral play, which helps when the pad hole spacing does not line up perfectly with a fixed-hole lug. If your equipment has a single-hole terminal, use a one-hole lug instead.
4) Is the LAC402 rated for 600 V service entrance and panel work?
Yes, it carries a 600 V rating, which covers typical service entrance, feeder, and panelboard terminations. The conductor temperature rating is 90 C, so it can be used with THHN/THWN-2 and XHHW-2 at their 90 C insulation rating where the terminal and equipment ratings allow.
5) Can I use this aluminum lug on copper cable, or is it aluminum-only?
The LAC402 is an aluminum-body compression lug, and aluminum compression lugs of this type are dual-rated for aluminum or copper conductors. Terminating aluminum cable, apply the joint compound per the installation instructions and clean the conductor before crimping.
6) Does the LAC402 come with bolts, washers, or heat shrink?
No. It ships as a bare lug, sold each, with no insulation and no hardware. You supply the bolt, nut and washers to suit the pad, plus any heat shrink or boot you want over the barrel, and the crimp die for your tool.
7) Should I use a compression lug like this or a mechanical set-screw lug for a 4/0 feeder?
A compression lug such as the LAC402 makes a permanent, crimped connection that does not need retorquing, which is why it is preferred on service and feeder terminations that get inspected once and closed up. A mechanical set-screw lug is the choice when you need to be able to remove the conductor later or you have no crimp tool on site. If you do not own a hydraulic or battery compression tool with the correct die, go mechanical.
8) Where is the Blackburn LAC402 made?
Mexico. That matters for buyers with country-of-origin reporting or trade-agreement documentation requirements on electrical material; the MPN to reference on submittals is LAC402.
