Color-Keyed 60275NT – Frequently Asked Questions

1) What cable sizes do these Color Keyed one-hole aluminum lugs cover?
The Color Keyed narrow-tongue, long-barrel aluminum lugs are offered in four conductor sizes: 350, 500, 600 and 750 MCM, ordered as 60267NT (350), 60273NT (500), 60275NT (600) and 60278NT (750). Pick the lug by the conductor you are terminating, not by the cable OD, and use one lug per conductor.
2) Will a 1/2 inch stud lug bolt to my switchgear pad?
The bolt hole is sized for a 1/2 inch stud, which is the common pad and bus-bar stud size on commercial switchgear and panel terminations. It is a one-hole tongue, so it lands on a single stud or a single drilled pad hole. If your pad is drilled two-hole NEMA spacing, a one-hole lug will not pick up both holes and you need a two-hole tongue instead.
3) Are these lugs rated for 35 kV medium-voltage terminations?
Yes, the voltage rating is 35 kV, which covers medium-voltage distribution and substation terminations. The lug itself carries no insulation, so the dielectric at the connection is whatever your termination kit or tape build provides.
4) Can I use these aluminum lugs on copper conductors?
These are aluminum-bodied lugs. Aluminum compression lugs of this type are normally marked for the conductor material they are rated to accept, so check the stamping on the barrel before terminating copper. The barrel is sized by the MCM values offered (350, 500, 600, 750), and the body material is aluminum.
5) Do these come insulated or will I need to insulate the termination myself?
They ship bare. Insulation material is listed as none, so the barrel and tongue are uninsulated metal and you insulate the completed connection yourself with heat shrink, tape build, or a termination kit appropriate to the 35 kV rating.
6) Why a long-barrel narrow-tongue lug instead of a standard short-barrel lug?
Long barrel means more crimp length and more contact area on the conductor, which is what you want on large MCM cable and higher-voltage work. Narrow tongue keeps the pad footprint small, so it fits tight stud spacing inside switchgear and panel compartments where a wide tongue would foul the adjacent phase. If your pad is wide open and spacing is generous, a standard tongue lug is fine.
7) What does the color-keyed system on these lugs actually do for the installer?
The color on the barrel identifies which die and crimp the lug requires, so a crew can verify at a glance that the right lug went on the right conductor and the right die was used. It is an installation verification aid, not an electrical feature, and it is why these are sold as the Color Keyed / Blackburn line.
