Sta-Kon F4-10 – Frequently Asked Questions
1) What wire size and stud size does the Sta-Kon F4-10 ring terminal take?
The F4-10 is sized for 4 AWG conductor, and the ring tongue is a No. 10 stud size. If your conductor is a different gauge, you need a different part number in the series, since a non-insulated barrel crimped on undersized or oversized wire won't hold its pull-out strength.
2) Is the Sta-Kon F4-10 terminal rated for 600 volt circuits?
Yes, it carries a 600 V rating and is UL recognized under file E9809. That covers typical commercial panel, motor, and control-circuit terminations at 600 V and below.
3) Is this a non-insulated terminal, and do I need to add insulation after crimping?
The F4-10 is a bare, non-insulated copper ring terminal, so the barrel and the crimp are exposed metal. On anything where the lug could be touched or could fault to an adjacent conductor or enclosure, add heat-shrink or tape over the barrel yourself. If you'd rather not do that step, buy an insulated ring terminal in the same 4 AWG size instead.
4) Can I use the F4-10 on aluminum conductors?
No. It's a copper terminal with no listing for aluminum, so use it on copper conductors only. Aluminum needs a connector specifically marked AL or AL9CU with the proper inhibitor compound.
5) Why choose a ring terminal instead of a fork or spade terminal for a 4 AWG motor lead?
A ring tongue has to be unbolted to come off, so it cannot vibrate loose off the stud the way an open fork can. That's the reason ring terminals are specified for motor leads, grounding studs, and anything on equipment that moves. A fork terminal is only worth it when you need to drop the wire off a terminal block fast without pulling the screw all the way out. The F4-10 is the ring style, 4 AWG, No. 10 stud.
6) Is the Sta-Kon F4-10 made in the USA?
Yes, country of origin is the United States, which matters on Buy American and federally funded projects where domestic sourcing has to be documented in the submittal.
7) What does the F4-10 look like, and how do I identify it in a parts bin?
Bare metallic copper with no colored insulation sleeve, a tubular barrel at one end and a flat ring tongue at the other. The part is stamped F4-10, which reads as 4 AWG wire, No. 10 stud.
