Sta-Kon 14RBC-38 INS VINYL RING TERM 16-14 HD 3/8IN

The 14RBC-38 is sized for 16-14 AWG conductors. The green vinyl insulation is the color code that goes with that range on Sta-Kon terminals, so on a panel you can spot a 16-14 crimp without reading the barrel. Anything larger, like 12-10 AWG, needs a different terminal; the barrel will not accept it and a crimp on an oversized conductor will not hold.

The ring on the 14RBC-38 is a 3/8 inch size, so it goes over a 3/8 inch stud, bolt or busbar screw. It will also drop over anything smaller, but on a smaller screw you want a matching smaller ring so the washer and screw head capture the tongue properly rather than letting it spin.

Copper. That makes the 14RBC-38 a copper-conductor-only terminal, so use it on copper wire, not aluminum. Aluminum conductors need a terminal marked AL or AL9CU with the proper inhibitor compound.

Yes. The Sta-Kon 14RBC-38 carries a 600 V rating, which covers standard commercial control, lighting and power branch circuits, motor starters and panel terminations.

It is covered under UL file E9809. That is the detail an institutional or MRO inspector asks for when terminations have to be documented on a government, healthcare or school job.

The 14RBC-38 is a heavy-duty vinyl insulated ring terminal, meaning a thicker barrel and tongue than a standard-duty terminal of the same 16-14 AWG range. That matters where the lug sees vibration or repeated service, such as motor connections and equipment studs. For light control wiring that never gets disturbed, a standard-duty insulated ring is adequate. If you need the connection to come off without loosening the nut fully, use a spade or flanged fork terminal instead, not a ring.

The part to specify is Sta-Kon 14RBC-38: 16-14 AWG, 3/8 inch ring, heavy-duty, green vinyl. Sta-Kon numbering changes with both the wire range and the stud size, so a 14RBC-10 or similar is the same wire range on a smaller stud. Order by the full suffix, not just the 14RBC prefix.

Crimp it with a tool matched to insulated 16-14 AWG terminals. On most insulated crimpers that is the blue or color-coded 16-14 nest. A pliers-style uninsulated die will cut through the vinyl sleeve and leave an unreliable joint, so the insulated nest matters here. Nothing else is supplied with the terminal; the ring installs under the existing stud nut or screw.

Country of origin is the United States, which is what Buy American and domestic-preference procurement language on federal, transit and institutional work usually asks you to document.
