Color-Keyed 58161 – Frequently Asked Questions

1) Will a 4/0 AWG Color Keyed copper lug work on a 35kV cable termination?
Yes, it is rated to 35 kV, so it can be used in medium voltage terminations as well as 600V work. The lug itself is bare copper with no insulation, so the voltage rating depends on the termination kit, tape, or boot you build over it doing the insulating and stress control.
2) Can I use this on aluminum cable, or is it copper only?
Copper only. The lug is copper construction and is sized for 4/0 AWG copper conductor. For aluminum you need a lug marked AL or AL9CU with the appropriate barrel; putting aluminum in a copper-only barrel is not a listed connection.
3) I need two bolts on the pad. Will this lug work?
No. This is a one hole lug, so it lands on a single stud. A two hole pad needs a two hole lug with the correct hole spacing, otherwise you are down to one bolt and the lug can rotate under load.
4) Does the yellow color on this Color Keyed lug mean anything, or is it just paint?
On Color Keyed lugs the color identifies the conductor size the barrel is sized for, so yellow is the 4/0 AWG key. In the field that lets an inspector or the next electrician confirm the right barrel went on the right cable without reading stamped numbers, and it also helps sort phases on a crowded pad. Match the die color to the lug color when you crimp.
5) Is this a compression lug or a mechanical set screw lug?
It is a compression lug with a standard barrel, so it is installed with a hydraulic or battery crimp tool and the matching die, not with set screws. If you need a connector you can install with a hex key and reuse, you want a mechanical lug instead.
6) Is this copper lug UL listed for commercial and utility work?
Yes. It carries UL file E9809, which is what most specs and inspectors on industrial, switchgear, and utility terminations are looking for on a cable lug.
7) Is this one hole lug sold under Blackburn as well as Color Keyed?
Same product. The brand label is Color Keyed / Blackburn, with Color Keyed as the sub brand, so if your submittal or purchase order lists a Blackburn Color Keyed 4/0 one hole copper lug, MPNs 58161, 58163, and 58165 are the parts you are matching. Country of origin is Mexico.
