Sta-Kon F9033 – Frequently Asked Questions
1) What wire size does the Sta-Kon F9033 ferrule take?
The F9033 is sized for 4 AWG conductor, which is the 25 mm2 metric equivalent called out in the part description. If your conductor is a different gauge, you need a different ferrule number, since the barrel is fixed at a single size.
2) Is the Sta-Kon F9033 ferrule insulated or bare?
Bare. It is a non-insulated copper ferrule with a metallic finish, so there is no plastic collar to color-code the size or to shield the crimp. Where panel wiring requires an insulated collar at the terminal block, specify an insulated ferrule instead.
3) How long is the F9033 ferrule barrel?
The crimp barrel length is 1.26 inches on the F9033. That length matters when you are checking strip length and whether the finished ferrule will seat fully in a deep terminal block or lug without bottoming out.
4) Does the Sta-Kon F9033 ferrule carry a UL file?
Yes, it is covered under UL file E489056. For inspected commercial and industrial panel work that is the reference an AHJ or QA reviewer will ask for.
5) Why use a ferrule on stranded 4 AWG instead of landing the bare strands in the terminal?
A ferrule crimps the strands into a solid cylinder so the terminal screw clamps one body instead of loose wires. That stops strand splay, broken strands under the clamp, and the slow loosening that comes from strands relaxing under pressure. The F9033 does that job for 4 AWG copper conductor.
6) Can I crimp the F9033 with pliers or a standard terminal crimper?
No. A 4 AWG, 25 mm2 ferrule this size needs a proper hex or square-jaw ferrule crimp die rated for that cross-section. Pliers deform the barrel without compacting the strands, and the connection will loosen in service.
7) Where is the Sta-Kon F9033 ferrule made?
Germany. Country of origin is listed as Germany (DE), which is the detail procurement and government buyers usually need for sourcing documentation.
