Sta-Kon F71-TB – Frequently Asked Questions
1) What wire size does the Sta-Kon F71-TB ring terminal take?
The F71-TB is sized for 4 AWG conductor. It is a one-size barrel, so it should not be crimped onto smaller stranded wire without a reducing sleeve, and it will not accept anything larger than 4 AWG.
2) Can I use a 4 AWG non-insulated ring terminal on a 480V motor connection?
Yes. The Sta-Kon F71-TB non-insulated ring terminal carries a 600 V rating, which covers 480V three-phase motor and panel work. Because the barrel and tongue are bare copper with no insulating sleeve, you have to insulate the crimp yourself with heat shrink or tape to keep the required clearance inside the enclosure.
3) Is the F71-TB a UL listed terminal for an inspected installation?
The F71-TB is covered under UL file E9809 and rated 600 V, which is what an inspector looks for on a connector in a commercial panel or control cabinet. Keep in mind it is a bare, non-insulated lug, so the installed assembly still needs insulation applied over the crimp.
4) Is the Sta-Kon F71-TB copper or aluminum, and can I put it on aluminum conductor?
It is a copper terminal, so it is for copper conductor only. Crimping copper onto aluminum wire creates a dissimilar-metal joint that corrodes and loosens. For 4 AWG aluminum you need a lug marked AL or AL9CU with the proper inhibitor compound instead.
5) Should I use a non-insulated ring terminal or an insulated one for 4 AWG wire?
A non-insulated lug like the F71-TB is the one to use when you intend to cover the crimp with adhesive-lined heat shrink, when the terminal has to sit under a cover or boot, or when you want to inspect the crimp after it is made. An insulated terminal is faster on open terminal strips where no extra covering is wanted. Both land the same way on a stud; the difference is whether the insulation comes on the part or you add it.
6) Why pick a ring terminal instead of a fork or spade terminal on a 4 AWG feeder?
A ring tongue cannot vibrate off the stud if the nut backs off, which is why it is the standard choice for motor leads, battery and ground studs, and anything subject to vibration. A fork or spade slides out from under a loosened screw. The tradeoff is that the F71-TB requires removing the nut or screw entirely to install, so on a dense terminal block where screws are hard to reach a fork is quicker.
7) Does the F71-TB ring terminal come with insulation or heat shrink included?
No. It ships as a bare metallic copper terminal with nothing over the barrel. If the crimp needs to be insulated, order adhesive-lined heat shrink sized for a 4 AWG barrel separately. Mounting hardware for the stud is not part of the terminal either.
8) What is the exact part number to order the Sta-Kon 4 AWG non-insulated ring terminal?
Order it as Sta-Kon F71-TB. That is the manufacturer part number for the bare copper 4 AWG ring tongue terminal rated 600 V, and it is made in the United States.
9) Is this a US-made terminal for a job with domestic sourcing requirements?
Yes, the Sta-Kon F71-TB is listed with a country of origin of the United States, which matters on government, institutional, and federally funded work carrying domestic content clauses.
