Sta-Kon K971 – Frequently Asked Questions
1) What wire size does the Sta-Kon K971 ring terminal take?
The K971 is sized for 2/0 AWG through 3/0 AWG conductors. It is a tubular-barrel ring terminal, so the stripped conductor seats fully into the barrel before crimping. Anything smaller than 2/0 will not fill the barrel and should go on a smaller lug instead.
2) Will the Sta-Kon K971 work on aluminum conductors?
No. This is a copper lug intended for copper conductors. Aluminum feeders need an AL9CU or aluminum-rated connector with the appropriate inhibitor compound; putting bare aluminum into a copper-only barrel creates a galvanic corrosion problem at the joint.
3) Is the Sta-Kon K971 terminal insulated, and do I need to cover it?
It is a non-insulated lug, bare copper with no sleeve. On a 600 V circuit you will want heat shrink or an insulating boot over the barrel and any exposed conductor once it is crimped, unless the termination sits inside an enclosure where live parts are already guarded.
4) Can the K971 be used on 480V three-phase equipment?
Yes. The K971 carries a 600 V rating, which covers 120/208, 277/480, and 600 V systems. It is UL recognized under file E9809.
5) Is the K971 a compression lug or a set-screw lug?
It is a crimp-type tubular barrel lug, so it needs a hydraulic or hand compression tool with the correct die for 2/0 to 3/0 copper. There is no set screw. If you need a mechanical connection you can make with a hex key and no crimper, use a set-screw mechanical lug instead.
6) What is the part number and origin of this Sta-Kon heavy gauge ring lug?
Manufacturer part number K971 from Sta-Kon, a non-insulated copper tubular ring terminal made in Mexico. Metallic bare copper finish, no color coding, so identify it by the printed barrel marking rather than sleeve color.
