Sta-Kon RA18-12 – Frequently Asked Questions
1) What wire sizes does the Sta-Kon RA18-12 ring terminal accept?
The RA18-12 is sized for 22 to 16 AWG stranded copper conductor. Red insulation is the standard color code for that range, so if the wire you are terminating is 14 AWG or larger, this is the wrong terminal and you need a blue (16-14) or yellow (12-10) barrel instead.
2) Is this ring terminal rated for 600 volt control and power wiring?
Yes, the RA18-12 carries a 600 V rating, which covers typical motor control panels, lighting circuits, and line voltage field wiring. It is UL recognized under file E9809.
3) Why pick a ring terminal over a fork or spade for a panel terminal block?
A ring terminal is a closed tongue, so it cannot back off a loosened stud the way a fork or spade can. On vibrating equipment, grounding bolts, and anything an inspector will pull on, the closed ring is the one to use. The tradeoff is that you have to fully remove the nut or screw to install it, so a spade is faster where you are servicing a block repeatedly.
4) Is the RA18-12 barrel copper, and will it work on aluminum wire?
The barrel is copper, so it is intended for copper conductors only. Aluminum wire needs a terminal marked AL or AL9CU with the appropriate inhibitor compound. The nylon insulating sleeve over the barrel gives the crimp strain support and keeps the connection insulated right up to the ring.
5) Do I need a special crimp tool for Sta-Kon nylon insulated terminals?
Use an insulated-terminal crimp tool with the red (22-16) nest, matching the barrel color. A nylon insulated barrel crimps through the sleeve, so an uninsulated or open-barrel die will split the nylon and leave the conductor loose. Pull-test the first crimp before you run the rest of the panel.
6) Are Sta-Kon RA18-12 terminals made in the USA?
Yes. Country of origin on the RA18-12 ring terminal is the United States, which matters on federal, military, and other Buy American specified jobs where domestic origin has to be documented.
7) What is the exact part number to order this red 1/2 inch ring terminal?
Order Sta-Kon RA18-12. That is the manufacturer part number for the nylon insulated red ring terminal, 22-16 AWG, 1/2 inch bolt.
