Sta-Kon RA18-516 – Frequently Asked Questions
1) What wire sizes does the Sta-Kon RA18-516 ring terminal accept?
The RA18-516 is sized for 22 to 16 AWG stranded copper wire. Red insulation is the standard color code for that range, so the red barrel is your quick visual check on the job that you grabbed the right terminal and not the blue 16-14 AWG size.
2) Will this ring terminal fit a 5/16 inch stud or bolt?
Yes. The RA18-516 has a 5/16 inch ring tongue, so it lands on a 5/16 inch stud, screw, or bolt. Because it is a closed ring rather than a spade or fork, the terminal cannot pull off the stud if the nut backs off, which is why ring tongues are specified for vibration-prone equipment and panel grounds.
3) What is the barrel made of, and can I use it on an aluminum conductor?
The barrel is copper, so it is intended for copper conductors only. Terminating aluminum wire with a copper-only lug invites galvanic corrosion and a high-resistance joint; for aluminum you need a connector marked AL or AL9CU instead.
4) Is this terminal rated for 600 volt control and panel wiring?
Rated 600 V, which covers standard control panel, motor control, and line-voltage branch circuit terminations. The nylon insulation sleeve is what carries that rating, and it also resists cracking during crimping better than vinyl, so it holds up in cold installs and tight panel bends.
5) Is the Sta-Kon RA18-516 ring terminal UL listed?
It carries UL file E9809. For an MRO or institutional spec that calls for listed connectors on 600 V wiring, that file number is the reference to put on the submittal.
6) Do I need a special crimper for these nylon insulated ring terminals?
Yes, use an insulated-terminal crimp tool matched to the 22-16 AWG color-coded die, typically the red nest. Open-barrel or non-insulated jaws will split the nylon sleeve and leave an unreliable crimp. Nothing is supplied with the terminal itself, so the crimp tool is a separate purchase.
7) Is this ring terminal made in the USA for a government or federal job?
Country of origin is the United States, which is what a government, education, or federal procurement buyer needs for a domestic-content line item. Order by the manufacturer part number RA18-516 to keep the right origin on the submittal.
