Color-Keyed 54270 – Frequently Asked Questions

1) What cable size does the purple Color Keyed two hole copper lug take?
It is sized for 4/0 AWG conductor only. Color Keyed lugs are die-indexed by color, and purple is the 4/0 AWG code on this standard barrel two hole lug. Crimping a smaller or larger conductor into it will not give you a compliant termination, so match the conductor to the color.
2) Will this lug bolt to a 1/2 inch stud on my bus bar or breaker pad?
Yes. The pad is drilled for 1/2 inch hardware, with two holes rather than one, so it bolts to a 1/2 inch stud or two 1/2 inch bolt positions on a bus bar, breaker pad, or ground bar. The two hole pattern also keeps the lug from rotating under torque, which is why it is specified over a one hole lug on vibrating or high-current gear.
3) Can I use this lug on a 15 kV or 25 kV medium voltage cable termination?
Yes. The lug carries a 35 kV rating, so it covers 15 kV and 25 kV class work as well as 35 kV systems. Typical use is utility substation connections, medium voltage equipment terminations, and industrial power distribution.
4) Can I put this copper lug on aluminum conductor?
No. It is a copper-bodied lug for copper conductor. For aluminum or dual-rated runs you need an AL9CU listed connector. Pairing bare copper with aluminum also invites galvanic corrosion at the joint.
5) Does this 4/0 copper lug come insulated, or do I have to tape or sleeve it after crimping?
No insulation on it. The barrel and pad are bare copper, so the installer covers the termination with tape, heat shrink, or a cold shrink boot per the job spec. The purple is a die-index color marking, not an insulating jacket.
6) Is the purple Color Keyed lug the same thing as a Blackburn lug?
Same product line. Color Keyed is the sub-brand label and the part is branded Color Keyed / Blackburn, so a drawing calling out either name is pointing at the same connector family. Order by part number 54270 for the 4/0 AWG purple standard barrel with the 1/2 inch bolt size.
7) Why would I buy color coded lugs instead of plain ones for a phase-identified panel?
Two reasons on a job site. The color tells the crimper which die index to use, which cuts wrong-die errors on a long day of terminations, and it stays visible in the panel afterward so anyone tracing conductors can read the termination at a glance. Purple is the 4/0 AWG index on this standard barrel line.
8) Where are these Color Keyed copper lugs made?
Manufactured in Mexico. If you are working a project with domestic sourcing requirements, that country of origin is what will be on the submittal.
