Blackburn LCN300 – Frequently Asked Questions
1) What wire size does the Blackburn LCN300 lug take?
The LCN300 is sized for 300 kcmil copper conductor. It is a single-conductor compression lug, so one 300 kcmil cable per barrel. If your feeder is 250 kcmil or 350 kcmil, go to the matching LCN part for that size rather than crimping this one down or forcing a larger cable in.
2) Will the Blackburn LCN300 bolt to a 1/2 inch stud on my panel bus?
Yes. The tongue is punched for 1/2 inch stud size, two holes, so it bolts to a 1/2 inch bus stud or landing pad. Two-hole tongues resist rotation under torque and vibration, which is why they get specified on switchgear and generator terminations over single-hole lugs.
3) Is this lug rated for aluminum conductor or copper only?
Copper only. The LCN300 is a copper-bodied, copper-conductor compression lug. For aluminum or dual-rated feeders you need an AL9CU-marked connector instead, not this one.
4) Is the Blackburn LCN300 UL listed for inspection sign-off?
It carries UL file E9809, which is the reference an inspector or spec reviewer will want for a compression termination on a copper feeder.
5) What does the white color code on the Blackburn LCN300 mean when I'm crimping it?
White is the die color code for this barrel. Blackburn long barrel copper lugs are color coded so the installer can match the connector to the correct die index on the compression tool, and the LCN300 lands on white. Verify the die marking against the color on the barrel before you make the crimp, since an undersized die gives a loose termination and an oversized one shears the barrel.
6) Why choose a long barrel lug instead of a standard barrel for a 300 kcmil feeder?
A long barrel takes two crimps instead of one, which gives more conductor-to-barrel contact area and a mechanically stronger pull-out resistance. That is why long barrel copper lugs like the LCN300 get specified on service entrance, generator, and switchgear terminations where the cable is under strain or the connection is critical. A short barrel is fine for lighter tap work inside an enclosure where space is tight.
7) Does the LCN300 come with the bolts and washers to land it?
No. It is sold as the lug only, each, so the 1/2 inch bolt, nut, washers, and any belleville or insulating hardware for the landing come from your own kit or the equipment manufacturer. Plan on the compression die set as well, since this is a crimp lug, not a set screw or mechanical connector.
8) Can I use the Blackburn LCN300 to replace an existing mechanical set screw lug on 300 kcmil copper?
Only if the equipment terminal accepts a bolted two-hole tongue on 1/2 inch studs. The LCN300 is a compression lug, so it is crimped onto the conductor with a hydraulic tool rather than torqued onto it with set screws. Where the gear has a factory set screw lug in a lug well, you generally keep that connector type. Where the gear has a drilled bus pad, this bolts straight on.
