Sta-Kon F9024 NON-INS FERRULE 8, 10 MM2, LG .709

The F9024 wire ferrule is sized for 8 AWG conductor, which is the 10 mm2 metric equivalent called out in the part description. If you are terminating 10 or 12 AWG control wiring, this barrel is too large to crimp down properly and you need a smaller ferrule in the same family.

Yes. The F9024 is covered under UL file E489056, which is the reference an electrical inspector or panel shop QA will want cited on a control panel build using 8 AWG ferruled conductors.

Barrel length is .709 inch. That is the length of copper sleeve that goes into the crimp, so strip your 8 AWG conductor to roughly that dimension plus whatever the terminal block jaw requires so no bare strands sit outside the ferrule.

It is a non-insulated ferrule, bare copper with no plastic collar. That gives you a smaller outside diameter at the entry of a tight terminal block, but it also means no strain relief and no color coding by size, so on dense control panels where techs identify conductors by ferrule color an insulated type is the better choice.

Ferrules need a hex or square four-indent ferrule crimp die, not the oval die used for insulated ring and fork terminals. The F9024 is a bare copper barrel sized for 8 AWG / 10 mm2, so set your crimp tool to the 10 mm2 station. Using a lug crimper flattens the barrel and it will not seat in a terminal block.

A copper ferrule gathers all the strands into one solid cylinder so the terminal screw clamps the whole conductor instead of pinching a few strands and letting the rest splay out. On 8 AWG stranded that matters, because a partially clamped conductor loses contact area, runs hot, and backs out under vibration. The F9024 barrel is the copper sleeve that does that job.

Order it as Sta-Kon F9024. That is the manufacturer part number, and the part is made in Germany, which is worth noting if your project requires country of origin documentation on submittals.
