Sta-Kon RA480 – Frequently Asked Questions
1) What stud or screw size does the Sta-Kon RA480 ring terminal fit?
The RA480 is built for a No. 8 stud or screw. The ring tongue slips over the No. 8 terminal screw or bolt and is captured when the screw is tightened, so it stays put even if the fastener loosens slightly, which is why ring tongues get used on vibrating equipment and panel terminal blocks instead of spade tongues.
2) Is the Sta-Kon RA480 ring terminal UL listed for inspected commercial work?
It is covered under UL file E9809, which is what an inspector or a spec writer on an institutional job is looking for on a wire termination. Combined with the 600 V rating, it is usable in commercial panel and equipment wiring.
3) What is the barrel on the RA480 ring terminal made of, and does it matter for aluminum conductors?
The crimp barrel is copper, so it is intended for copper conductors. Copper-only terminals should not be used on aluminum wire; aluminum needs a connector specifically rated AL or AL9CU with the proper inhibitor compound.
4) What is the difference between a rectangular ring terminal and a standard round ring terminal?
The RA480 has a rectangular tongue rather than a round one. The narrower straight sides let it sit between closely spaced screws on a terminal block or breaker landing where a round tongue would overlap the neighboring terminal, while still giving the closed ring that cannot pull off the stud. If you have open space around the stud, a round ring tongue does the same electrical job.
5) Why is this ring terminal red, and does the color mean anything?
Red is the insulation color code on the RA480 and it identifies the wire size range the barrel is sized for. On a job where crews are terminating several gauges at once, the color is how an electrician picks the right terminal out of the bin without reading the stamp, and how an inspector spots a mismatched crimp. The nylon sleeve itself is there for abrasion resistance and to support the wire where it leaves the barrel.
6) Are Sta-Kon RA480 terminals made in the USA for government or Buy American jobs?
Country of origin on the RA480 is the United States, which is the data point procurement officers on federal, municipal and institutional contracts need when they are documenting domestic content.
