Sta-Kon RC485 – Frequently Asked Questions
1) What wire size does the Sta-Kon RC485 ring terminal crimp onto?
The RC485 is sized for 12-10 AWG conductor. Yellow is the standard color code for that range, so the insulation color tells you at a glance it is the 12-10 barrel and not a 16-14 (blue) or 22-18 (red). Stranded copper building wire in that range crimps into it with a 12-10 nest on the tool.
2) Is the Sta-Kon RC485 rated for 600 volt control and branch circuit work?
Yes, 600 V is the rating, which covers standard commercial control panels, motor leads and branch circuit terminations. It is UL recognized under file E9809.
3) Why choose a rectangular tongue ring terminal instead of a round ring or a fork terminal?
A rectangular tongue ring like the RC485 is a closed ring, so the connection cannot vibrate off the stud the way a fork or spade can once the screw loosens slightly. The rectangular tongue is narrower across than a standard round tongue, which helps where terminals sit shoulder to shoulder on a crowded terminal block or stud bar. If you need to drop wires in and out without pulling the screw all the way, use a fork instead.
4) Is the barrel on the RC485 copper, and does that matter for aluminum wire?
The terminal is copper, nylon insulated. Copper barrels are for copper conductor only. Aluminum feeders need an AL9CU or dual rated connector instead, crimping aluminum into a copper-only barrel is not a listed connection.
5) What is the difference between nylon insulated and vinyl insulated ring terminals?
The RC485 uses a nylon sleeve. Nylon takes more heat and abrasion than vinyl and resists cracking when the barrel is crimped hard, which is why it is the usual pick for motor connections and panel work that sees temperature cycling. Vinyl versions are the lower cost option for light duty, low temperature terminations.
6) Is the Sta-Kon RC485 made in the USA for a Buy American job?
Country of origin on the RC485 is the United States, which is what a government, institutional or federally funded project needs on the submittal for domestic sourcing requirements.
7) What part number do I order to match existing yellow 12-10 ring terminals in my panel?
Order Sta-Kon RC485. That is the manufacturer part number for the yellow nylon insulated rectangular ring, 12-10 AWG, No. 5 stud, so it standardizes with the same terminals already on your MRO shelf.
