Sta-Kon L972 – Frequently Asked Questions
1) What wire size does the Sta-Kon L972 ring terminal accept?
The L972 is sized for 3/0AN through 4/0 conductor. That is a heavy feeder or service-size lug, not something that will crimp down on anything smaller, so if you're terminating 1/0 or 2/0 you need a smaller lug in the same family rather than trying to make this one grip.
2) Can the Sta-Kon L972 be used on a 480 volt circuit?
The L972 carries a 600 V rating, so it covers 120/208, 277/480 and other common building power systems up to 600 volts. It is listed under UL file E9809.
3) Is the Sta-Kon L972 lug copper or aluminum, and can I put it on aluminum conductor?
The barrel is copper, so it is intended for copper conductor. Aluminum feeders need a lug rated for aluminum (or AL9CU dual-rated) along with the appropriate joint compound. Putting bare copper directly on aluminum is a galvanic problem you don't want inside a panel.
4) Is the Sta-Kon L972 terminal insulated, and does that matter for my install?
It is a non-insulated tubular ring terminal, so the barrel is bare copper after crimping. On 3/0 to 4/0 conductor at that size you normally finish it with adhesive-lined heat shrink or tape to cover the barrel and the strip, especially in a panel where live parts are close together. If you want factory insulation on the barrel, choose an insulated lug instead.
5) Do I need a special crimp tool for the Sta-Kon L972?
At 3/0 to 4/0, yes. A tubular copper lug this size is crimped with a hydraulic or heavy mechanical crimper using the die for the matching wire range, not with a hand ratchet tool meant for insulated terminals. The lug itself ships as the terminal only, so the tool, dies, and any heat shrink are separate.
6) Is the Sta-Kon L972 the right lug for a generator or battery cable termination?
It works wherever you're landing 3/0 to 4/0 copper on a 5/16 inch stud at up to 600 volts, which covers generator tails, transfer switch lugs, battery and inverter studs, and ground bars. Confirm the stud on your equipment is 5/16 before ordering, since the ring size is fixed and not field-drillable.
7) Where is the Sta-Kon L972 made?
The L972 ring terminal is manufactured in Mexico. For MRO and institutional buyers tracking country of origin on submittals, that is the declared origin for this part number.
