Blackburn LCN500 – Frequently Asked Questions
1) What wire size does the Blackburn LCN500 lug take?
The LCN500 is sized for 500 kcmil copper conductor. It is a single-conductor compression lug, so one 500 kcmil cable per barrel. If your feeder is a different size, you need a different catalog number, since compression lugs are not adjustable.
2) Will the LCN500 bolt to a 1/2 inch bus stud?
Yes. The LCN500 pad is drilled for 1/2 inch bolt or stud size, and it is a two-hole tongue, so it needs two 1/2 inch holes on the bus or pad, not one. Two-hole termination resists rotation under torque, which is why switchgear and generator pads often spec it.
3) Can I use this copper lug on aluminum conductor?
No. The LCN500 is a copper-only (CU) compression lug. Running aluminum cable into a copper-rated barrel is not a listed connection; for aluminum you need an AL9CU dual-rated or aluminum-bodied lug in the same 500 kcmil size.
4) What does the long barrel on a compression lug do, and when do I need one instead of a standard barrel?
A long barrel gives room for two crimps instead of one, which is what many specs call for on large feeders and on high-vibration or high-current terminations such as generator, transformer, and switchgear connections. If your spec only calls for a single crimp on 500 kcmil, a standard barrel lug will do; where the drawing says two-crimp or long barrel, the LCN500 is the configuration to order.
5) Why is the LCN500 brown, and does the color mean anything for crimping?
Brown is the die color code on the lug. On compression connectors the color tells the installer which die and crimp setting to use in the hydraulic or battery tool, so match your die index to brown when terminating this 500 kcmil lug rather than guessing by barrel diameter.
6) Does the LCN500 come with mounting bolts, and how many do I need per termination?
The lug is sold as each, bare connector only. Hardware is not part of it, so plan on two 1/2 inch bolts with nuts and washers per lug, plus the correct brown compression die for the crimp.
7) What is the exact part number to order for a 500 kcmil copper two-hole long barrel lug from Blackburn?
Blackburn LCN500. That is the manufacturer part number for the copper two-hole long barrel compression lug, 500 kcmil conductor, 1/2 inch bolt size. It is made in Mexico.
