Sta-Kon L973 – Frequently Asked Questions
1) What wire size does the Sta-Kon L973 ring terminal take?
The L973 is sized for 3/0 through 4/0 conductor. It is a tubular-barrel, non-insulated copper lug, so the barrel is crimped directly onto the stranded conductor. If you are terminating smaller feeder cable, say 2/0 or 1/0, this barrel is oversized and the crimp will not hold.
2) Is the Sta-Kon L973 rated for 600 volt service panels?
Yes, the L973 carries a 600 V rating, which covers typical commercial feeder and panelboard work, and it is UL recognized under file E9809.
3) Can I use the Sta-Kon L973 on aluminum conductor?
The L973 is a copper lug. Use it on copper conductor in the 3/0 to 4/0 range. For aluminum or combination AL/CU feeders you need a lug specifically listed for aluminum, since a copper-only barrel on aluminum cable is not a listed termination.
4) Does the L973 terminal come insulated, or do I need to add heat shrink?
It is a non-insulated lug, bare copper with a metallic finish. Any insulation or phase identification at the termination has to be added separately, usually adhesive-lined heat shrink over the barrel.
5) What part number should I order for a 4/0 lug with a 3/8 inch hole?
Order Sta-Kon L973. That is the manufacturer part number for the non-insulated tubular ring lug covering 3/0 to 4/0 conductor with a 3/8 inch stud hole.
6) Where is the Sta-Kon L973 lug made, for Buy American or sourcing documentation?
Country of origin on the L973 is Mexico. If your project carries a domestic-content requirement, that will not satisfy a Buy American clause.
