Color-Keyed 54878BE – Frequently Asked Questions

1) What cable size do the Color Keyed green two-hole long-barrel copper lugs take?
They are made for 600 kcmil copper conductor. The green color key identifies the die/index for the crimp, so the lug body, the cable size, and the die all have to agree for the termination to be rated. If your feeder is a different kcmil, you need the lug keyed to that size, not this one.
2) Will these lugs bolt to a 1/2 inch stud bus bar?
Yes. The pad is drilled for 1/2 inch stud size, two-hole pattern, which is what most medium voltage switchgear and substation bus landings use. Two holes also keep the lug from rotating on the pad under torque and vibration.
3) Are these copper compression lugs rated for medium voltage, or only 600 V?
Rated to 35 kV, so they can be used on medium voltage feeders and substation terminations, not just 600 V building wiring. They are UL listed under file E9809.
4) Can I use these copper lugs on aluminum conductor?
No. These are copper lugs made for copper cable. Terminating aluminum conductor in a copper-only barrel is a dissimilar-metal connection and is outside what this lug is listed for. For aluminum feeders use a lug marked AL9CU or an aluminum-rated compression lug in the matching kcmil.
5) Do these lugs come insulated, or do I have to cover the barrel myself?
The barrel is bare copper with no insulation on it. On a 35 kV termination you supply the insulating system yourself, whether that is heat shrink, cold shrink, or the stress cone and tape build in the termination kit. Plan the shrink length over the long barrel before you crimp.
6) What is the difference between a long-barrel lug and a standard short-barrel lug?
The long barrel takes more crimps along its length, which spreads the mechanical load and increases contact area with the conductor. That is why it is the usual choice on large conductors like 600 kcmil and on medium voltage work where pull-out strength and current-carrying stability matter. A short barrel is fine on smaller conductors and tight terminal spaces, but it gives you fewer crimp positions.
7) Is this the same thing as a Blackburn lug? I need to match what the last crew installed.
Yes, Color Keyed is the Blackburn color-key line, labeled Color Keyed / Blackburn. If your existing terminations were made with Blackburn green-keyed 600 kcmil lugs, this is the same product family and the same color index, so your crimp dies carry over.
8) What part number do I order for the 1/2 inch bolt size version of this green 600 kcmil lug?
The 1/2 inch bolt size, two-hole long-barrel green copper lug is MPN 54878BE. That bolt size is the only one offered on this lug, so the 1/2 inch pad is what you get.
9) Do I need anything besides the lug to finish a 600 kcmil termination?
Yes. The lug itself is the only item here. You still need a hydraulic compression tool with the green-keyed die for 600 kcmil copper, the 1/2 inch bolts, nuts and Belleville washers for the two-hole pad, and your insulating or termination kit over the bare barrel.
10) Does the green color on these lugs mean they are for grounding?
No. Green here is the crimp color key that identifies the die and conductor index, not a ground designation. Do not read it as a phase or grounding conductor color code.
