Color-Keyed 54918BE – Frequently Asked Questions

1) What cable size does the Color Keyed brown compression lug take?
It terminates 500 kcmil conductor. The brown color code on Color Keyed (Blackburn) lugs corresponds to that 500 kcmil die/cable size, so the color is how you confirm the right barrel on the job without reading the stamp. Part number 54918BE.
2) Will this lug bolt to a 1/2 inch stud on my switchgear bus?
Yes. The tongue is drilled for a 1/2 inch stud, one hole only, so it lands on a single 1/2 inch bolt or stud connection. If your pad is two-hole NEMA spaced, you need a two-hole lug instead, not this one.
3) Can I use this copper lug on aluminum 500 kcmil conductor?
No. This is a copper-bodied lug for copper conductor. Aluminum cable needs an aluminum or dual-rated AL9CU connector; putting bare copper on aluminum invites galvanic corrosion at the barrel. Order the aluminum-bodied equivalent for AL runs.
4) Is a 35kV rated lug required, or can I use it on 600V gear too?
The 35 kV rating is the ceiling, not a minimum. A lug rated 35 kV terminates fine on lower voltage systems, so the same 500 kcmil copper barrel works in a 600V distribution panel or a medium voltage termination. The rating matters because the barrel geometry and compression are qualified for stress-cone and MV terminations.
5) Does this compression lug come with insulation or a boot?
No insulation. The barrel and tongue are bare copper, so you tape, heat shrink, or boot the termination yourself per your spec. Budget for the shrink tubing or an insulating boot separately.
6) What does the long barrel version get me over a standard barrel lug?
A long barrel takes two compression crimps instead of one, giving more contact area and a stronger mechanical grip on 500 kcmil conductor. Electricians spec it where cable pull or vibration is a concern, and on medium voltage terminations where the 35 kV rating applies. A standard barrel is fine for short, well supported runs at lower current.
7) How do I make sure I crimp this with the right die?
Match the die to the color code. Brown is the Color Keyed index for this 500 kcmil copper barrel, so you set your hydraulic or battery compression tool to the brown die set and index the stamped die number on the barrel. The color exists so a crew can verify the crimp after the fact by sight.
8) What is the manufacturer part number for the brown 500 kcmil one-hole lug with a 1/2 inch bolt hole?
54918BE, sold under the Color Keyed sub-brand of Blackburn. One hole, 1/2 inch stud, long barrel, copper, made in Mexico.
