Sta-Kon C133 – Frequently Asked Questions
1) Will the Sta-Kon C133 fit a #6 screw or stud?
Yes. The C133 fork tongue is sized for a No. 6 stud, so it slips under a loosened #6 terminal screw without pulling the wire out of the block. Larger studs need a different tongue size.
2) Can I use the C133 fork terminal on aluminum wire?
No. It's a copper terminal, intended for copper conductors. Aluminum conductors need a terminal rated and listed for aluminum (AL or AL/CU) with the proper inhibitor compound; crimping bare copper onto aluminum invites galvanic corrosion at the joint.
3) Is a fork terminal or a ring terminal the right choice for a control panel terminal block?
A fork (spade) terminal like the C133 slides in and out under a partly backed-off screw, which is why panel builders and electricians use it on terminal strips and relay bases they expect to service. A ring terminal is captive and won't walk off under vibration, so it's the better pick on motor leads, grounds, and anything subject to shake. If the connection gets re-terminated often, the fork wins; if it has to stay put, go ring.
4) What voltage can the Sta-Kon C133 fork terminal be used at?
Rated 600 V, which covers standard commercial and industrial control and branch circuit work up to 600 volts. It is UL recognized under file E9809.
5) Does the C133 terminal come with insulation, and do I need to sleeve it?
It's a non-insulated copper fork terminal, bare metal with no sleeve. If the connection sits in a crowded enclosure or near adjacent live terminals, add heat shrink or a nylon insulating cap over the crimped barrel yourself. Where the terminal strip already provides barriers or covers, bare is normal.
6) Can I crimp the Sta-Kon C133 with pliers, or do I need a proper tool?
Use a crimper. The C133 is a bare copper barrel, and a UL-recognized termination depends on the barrel being compressed with the correct die for 12-10 AWG. Pliers deform the barrel unevenly and give you a joint that loosens and heats up. A ratcheting non-insulated terminal crimper with a 12-10 nest is what the job calls for.
7) Are Sta-Kon C133 terminals made in the USA?
Country of origin is the United States. That matters on government, military, and institutional jobs carrying domestic-sourcing requirements, where the origin has to be documented on submittals.
8) What is the Sta-Kon part number to order for a 12-10 AWG fork terminal on a #6 stud?
Order Sta-Kon C133. That's the manufacturer part number for the uninsulated fork terminal covering 12-10 AWG wire with a No. 6 tongue.
