Sta-Kon RA481 – Frequently Asked Questions
1) Can I use the Sta-Kon RA481 ring terminal on a 480 volt control circuit?
Yes. The RA481 nylon insulated ring terminal carries a 600 V rating, which covers 480 V control and power wiring as well as the usual 120/277 V building circuits.
2) Is the Sta-Kon RA481 terminal UL listed for use in a panel or equipment build?
The RA481 is built to UL file E9809, which is what an inspector or a panel shop QA check will look for on an insulated crimp terminal. Pair that with the 600 V rating and it suits control panel and equipment wiring.
3) What is the difference between a rectangular ring terminal like the Sta-Kon RA481 and a standard round ring tongue?
The RA481 has a rectangular tongue rather than a round one. The flat sides keep it from rotating when it sits between adjacent lugs on a crowded terminal strip and let it fit narrow barrier channels where a round tongue would overhang. Electrically it is the same closed ring connection, so it still cannot be pulled off a loosened screw the way a spade or fork terminal can.
4) Is the Sta-Kon RA481 ring terminal copper, and will it work on aluminum conductors?
The barrel is copper, so the RA481 is intended for copper conductors only. Aluminum wire needs a terminal specifically rated AL or AL/CU with the appropriate inhibitor; using a copper-only barrel on aluminum invites a hot joint.
5) What does the red insulation on the Sta-Kon RA481 terminal mean on the job?
Red is the standard color code used on small insulated crimp terminals, and it is also how you pick the matching crimp die or nest on a color-coded crimp tool. The nylon sleeve on the RA481 is tougher and more abrasion resistant than vinyl, which is why it is the common choice for panel work and harnesses pulled through conduit or trays.
6) Is the Sta-Kon RA481 ring terminal made in the USA for projects with domestic sourcing requirements?
Country of origin on the RA481 is the United States, which is what procurement needs on file for federal, state, and institutional jobs carrying domestic content language.
