Sta-Kon RCT863 – Frequently Asked Questions
1) What stud or screw size does the Sta-Kon RCT863 ring terminal fit?
The RCT863 ring tongue is sized for a 1/4 inch stud or screw, so it drops over a 1/4-20 terminal block stud, ground lug screw, or breaker stud without filing the ring. If your stud is #10 or 5/16, this is the wrong tongue size.
2) Can I use the Sta-Kon RCT863 ring terminal on a 480 V control circuit?
Yes. The RCT863 is rated 600 V, which covers 120, 240, 277 and 480 V control and power circuits up to that limit.
3) Is the Sta-Kon RCT863 ring terminal UL recognized for an inspected panel job?
It carries UL file E9809, which is what an inspector or a panel-shop QC reviewer looks for on a terminated lug. That makes it usable in UL-reviewed control panels and MRO repairs where recognized components are required.
4) Why choose a fluoropolymer insulated ring terminal instead of a standard vinyl or nylon one?
Fluoropolymer insulation handles higher heat and holds up better against oils, solvents and fuels than vinyl. On the RCT863 that matters in engine compartments, boiler rooms, and machine enclosures where a vinyl sleeve goes brittle or softens. For a clean, climate-controlled control cabinet, a nylon or vinyl insulated ring of the same stud size does the same electrical job.
5) Is the Sta-Kon RCT863 ring terminal copper, and does that matter for aluminum conductors?
The barrel is copper, so it is intended for copper conductors. Terminating aluminum wire in a copper-only lug is a dissimilar-metal connection and needs a lug marked AL or AL9CU instead.
6) Do I need a crimp tool for the Sta-Kon RCT863, or can I use pliers?
It is a crimp ring terminal, not a solder or screw-clamp lug, so it needs a proper ratcheting crimper sized for insulated terminals. Pliers deform the barrel unevenly and the connection will not hold up mechanically or carry its rated 600 V duty reliably. No tool is supplied with the terminal.
7) Are Sta-Kon RCT863 ring terminals made in the USA for government or Buy American work?
Country of origin on the RCT863 is the United States, which is the data point procurement officers on federally funded or Buy American jobs ask for when qualifying a terminal.
