Blackburn LCN40 – Frequently Asked Questions
1) What bolt or stud size does the LCN40 lug pad fit?
The tongue is drilled for 1/2 inch hardware, and it's a two-hole pad, so you're landing it on two 1/2 inch studs or bolts. If your bus or ground bar is drilled for a single bolt, a one-hole lug is the part you want instead.
2) Why is the Blackburn LCN40 purple, and does the color mean anything for crimping?
Purple is the die color code for this barrel. The lug is marked purple so the installer matches it to the correct compression die in the crimp tool, which is how you get a UL-recognized termination rather than a guess. Confirm your tool carries the purple die index before crimping 4/0.
3) Can I use the LCN40 on aluminum conductor?
No. It's a copper-bodied lug, so use it on copper conductor only. For aluminum or a dual-rated run you need an AL9CU-rated connector, which this is not.
4) What does the long barrel version of this copper lug get me over a standard barrel?
A long barrel takes two crimps instead of one, which is what specs and inspectors often call for on service entrance and grounding-electrode terminations where pull-out strength matters. The LCN40 is the long barrel build in copper for 4/0. If the spec only calls for a single crimp, a standard barrel lug is fine and easier to fit in a tight gutter.
5) Is the Blackburn LCN40 lug UL listed?
It carries UL file E9809. That's the reference an inspector or submittal reviewer will want for a compression connector on a service or grounding termination.
6) What part number should I put on the submittal for a 4/0 copper two-hole compression lug?
Blackburn LCN40 is the manufacturer part number, a copper long barrel two-hole lug for 4/0 with 1/2 inch bolt holes, made in Mexico.
7) Is the LCN40 sold individually or in a bag of multiples?
Sold each, so quantity ordered equals lugs received. Count your terminations, not your bags, when you order for a panel or switchboard job.
