Sta-Kon L974 – Frequently Asked Questions
1) What wire size does the Sta-Kon L974 ring terminal take?
The L974 is sized for 3/0AN through 4/0 conductor. It's a tubular, non-insulated ring terminal in copper, so the barrel is crimped directly onto the stripped conductor with the matching die for that range. Undersized conductor in an oversized barrel is the usual cause of a loose, high-resistance termination, so match the die and the conductor to the stated range rather than forcing a smaller cable into it.
2) Can I use the L974 copper lug on aluminum conductor?
No. The L974 barrel is copper and is specified for 3/0AN to 4/0 conductor in that material. Terminating aluminum in a copper-only lug creates a dissimilar-metal joint that corrodes and loosens. For aluminum feeders use a lug marked AL9CU or aluminum-rated with the appropriate inhibitor compound.
3) Is the Sta-Kon L974 terminal rated for 600 volt circuits?
600 V is the rating on the L974, which covers standard commercial and industrial power distribution, panelboard, motor feeder, and switchgear terminations. It carries a UL file reference of E9809.
4) Does a non-insulated lug like the L974 need heat shrink or tape after crimping?
The L974 has no insulating sleeve on the barrel, so the crimp and the exposed conductor strands are bare metal after installation. Inside an enclosure with adequate clearance that's normally fine and it's how most feeder terminations are done. Where you need phase identification or clearance is tight, installers add adhesive-lined heat shrink over the barrel after crimping. Insulation is not supplied with the terminal.
5) I'm standardizing lugs across a facility. What exactly is the Sta-Kon L974?
Sta-Kon L974 is the manufacturer part number for a non-insulated tubular ring terminal, bare copper, 3/0AN to 4/0 wire range, 7/16 inch bolt hole, rated 600 V, UL file E9809. Order by L974 to get that exact combination; Sta-Kon's L-series numbers change with both the wire range and the bolt hole, so a nearby number is a different lug.
