Sta-Kon C10-6F NONINS FORK TERM, 12-10, No6, METAL

The C10-6F is sized for 12 to 10 AWG conductors. Anything smaller, like 16-14 AWG, will not hold a reliable crimp in this barrel, and anything larger than 10 AWG won't enter it. Match the terminal to the actual conductor gauge, not to the breaker size.

It is a No. 6 stud terminal, so the fork slips over a #6 screw or terminal stud. That is a common size on control terminal blocks, thermostats, and small device terminals. For a larger #8 or #10 stud you need a different tongue size.

The C10-6F carries a 600 V rating, so it covers 120, 240, and 480 V circuits. Because the barrel is bare metal, you need to maintain clearance or add heat shrink or a nylon sleeve where terminals sit close together inside a crowded enclosure.

Yes. The terminal is covered under UL file E9809. That file reference is what an inspector or a spec reviewer wants to see cited on a submittal for an electrical panel build.

A fork (spade) terminal like the C10-6F slides in under a loosened screw without pulling the screw all the way out, which is why panel builders and control techs use them for wiring that may be serviced or re-landed. A ring terminal requires removing the screw entirely but cannot vibrate off the stud, so it is the better call on motor terminals, grounding studs, and anything subject to vibration.

The terminal body is copper, so it is intended for copper conductors. Aluminum wire needs a terminal specifically rated AL or AL/CU, because copper-only lugs on aluminum lead to galvanic corrosion and loose connections over time.

Yes. Non-insulated terminals are crimped with a non-insulated (open barrel or oval/indent) die, not the color-coded insulated die used for vinyl and nylon terminals. Using an insulated die on a bare copper barrel gives an under-formed crimp that can pull out under load.

Country of origin is the United States. For federally funded or domestic-preference work, that is the data point procurement will ask for on the terminal line item.
