Blackburn LCN4-14 – Frequently Asked Questions
1) What voltage is the Blackburn LCN4-14 lug rated for?
35 kV. That puts it in medium-voltage territory, so it's usable on MV terminations as well as ordinary low-voltage gear. It carries UL file E9809.
2) Is the LCN4-14 a copper lug or aluminum?
Copper. That matters on two counts: it's intended for copper conductors, and on an all-copper connection you avoid the dissimilar-metal concerns you get bolting aluminum bodies to copper bus. The body is grey.
3) Why choose a long barrel lug instead of a standard barrel for a 4 AWG run?
A long barrel like the LCN4-14 gives you more crimp length, which normally means two crimps instead of one and a higher pull-out resistance on the conductor. Standard barrel lugs take a single crimp and are shorter overall, which helps where cabinet space behind the terminal is tight. If your spec or inspector calls for two-crimp terminations, the long barrel is what you want.
4) Is the LCN4-14 a compression lug or a set screw (mechanical) lug?
It's a compression lug, so it's installed with a hydraulic or battery crimp tool and the correct die, not a hex key. There is no set screw to torque. Plan on the die matching the barrel, and expect two crimps on the long barrel.
5) Does the Blackburn LCN4-14 come with mounting bolts?
No hardware is included. The LCN4-14 sells as a single lug, each, so bolts, nuts, washers and any anti-oxidant or insulating boot are separate line items. Order the 1/4 inch bolt hardware to suit the pad you're landing on.
6) Why use a two-hole lug instead of a single-hole lug on a ground bus or bonding pad?
Two bolt holes stop the lug rotating under fault current or vibration, which is why grounding and bonding pads in commercial gear are commonly drilled for two-hole pads. The LCN4-14 gives you that on 1/4 inch hardware. A single-hole lug can spin off its pad and is generally not accepted where a two-hole pad is specified.
7) What part number do I order for this two-hole long barrel copper lug?
Blackburn LCN4-14 is the manufacturer part number. It's a copper two-hole long barrel lug for 4 AWG with 1/4 inch bolt holes, made in Mexico.
