Sta-Kon RA733 – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RA733 ring terminal crimp onto?
The RA733 is sized for 22 to 16 AWG stranded copper conductors. The red insulation is the standard color code for that gauge band, so if you are pulling 14 AWG or heavier you need the next size up (blue for 16-14, yellow for 12-10), not this one.
2) Is the RA733 ring terminal UL listed, and what voltage is it rated for?
It carries UL file E9809 and is rated 600 V. That covers typical line voltage control panel, motor, and lighting circuit work; it is not a medium-voltage connector.
3) Should I use a ring terminal or a fork/spade terminal on a 3/8 inch stud?
Use the ring style, like the RA733, anywhere the connection is subject to vibration or where a loose terminal could slide off the stud, such as motor terminal boxes, ground studs, and battery or bus connections. A fork terminal slips on and off without removing the nut, which is handy for frequently serviced terminal strips, but it can back out if the nut loosens. The RA733 is the captive version for a 3/8 inch bolt in 22-16 AWG.
4) Is the RA733 terminal body copper, and does the nylon insulation matter?
The barrel and tongue are copper, which is what you want on copper conductors, no dissimilar-metal issue. The insulation is nylon rather than vinyl, so it resists cracking and abrasion better when terminals are bundled tight in a panel or pulled through a wireway, and it holds its shape at higher temperatures than PVC sleeving.
5) Do I need a special crimp tool for Sta-Kon insulated ring terminals?
Crimp it with a ratcheting insulated-terminal tool using the red die nest, which matches the 22-16 AWG color code. Pliers or an uncalibrated stamped tool will crush the nylon sleeve and give you a connection that pulls off. The insulation is crimped along with the barrel, so there is no separate sleeve to install.
6) Are these ring terminals made in the USA?
Country of origin on the RA733 is the United States, which matters if you are filling a government, school district, or federally funded job with domestic-sourcing language in the spec.
7) What is the exact part number to order for the red 22-16 AWG, 3/8 inch ring terminal?
Order Sta-Kon RA733. That single part number covers the red nylon insulated ring terminal, 22-16 AWG, 3/8 inch bolt size, with no finish or length options to specify.
