Sta-Kon BC14-14 NON-INS RING TERM, HD 16-14, 1/4, M

The BC14-14 is sized for 16 to 14 AWG stranded copper conductors. Run anything smaller than 16 AWG and the barrel won't grip properly after crimping; anything larger than 14 AWG won't seat in the barrel at all, so step up to a terminal in the 12-10 AWG range for those runs.

The ring tongue on the BC14-14 is drilled for a 1/4 inch stud or screw. It will drop over a 1/4-20 terminal stud or a #10 screw with a washer, but it is oversized for a #8 or smaller post, where a 1/4 inch ring can shift under the screw head.

The BC14-14 carries a 600 V rating, so it is good for 480V three-phase motor leads and control circuits. Because it is non-insulated, the crimp barrel and tongue are bare copper, so the connection has to be insulated after crimping, typically with heat shrink or tape, or made inside an enclosure or motor junction box where live metal is not exposed.

Yes, it carries UL file E9809. For institutional and MRO work where terminations have to be listed components, that file reference is what an inspector or spec reviewer is looking for.

Non-insulated terminals like the BC14-14 are the choice when the joint gets its own insulation, when heat rules out a vinyl sleeve, or when you need the bare barrel for inspection of the crimp. An insulated ring is faster on general panel and fixture wiring because the sleeve handles strain relief and covers the barrel in one step. Note that the non-insulated version needs a die for uninsulated terminals, not the colored insulated-terminal nest on a combination tool.

The body is copper with a metallic plated finish. Copper terminals belong on copper conductors; do not crimp them onto aluminum, which calls for a dual-rated aluminum connector and joint compound. For damp or outdoor locations the bare barrel should be sealed, since nothing on the terminal itself provides a moisture barrier.

BC14-14 is the manufacturer part number to order by. The first part identifies it as the heavy-duty non-insulated barrel for 16-14 AWG wire and the trailing 14 is the 1/4 inch ring size. If your stud is a different diameter, the wire range stays the same but you need the matching ring size instead of this one.

Yes, country of origin is the United States, which matters on government, education, and healthcare jobs carrying domestic sourcing requirements on electrical components.
