Sta-Kon RA863 – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RA863 ring terminal crimp onto?
The RA863 takes 22 to 16 AWG stranded copper wire. The red insulation is the standard color code for that gauge band, so if you are sorting a bin by color, red means 22-16 AWG on Sta-Kon nylon insulated terminals. Anything larger than 16 AWG will not seat in the barrel and will not crimp reliably.
2) What size bolt or stud will the RA863 ring fit over?
The ring is sized for a No. 8 bolt or screw stud. It will slip over a #8 machine screw or stud; on a 1/4 inch stud it will not go on, and on a #6 it will fit but sit loose unless you add a washer.
3) Is the RA863 terminal rated for 600 volt control and panel wiring?
Yes, the RA863 carries a 600 V rating, which covers typical control panel, motor control, and lighting circuit terminations. It is also UL listed under file E9809.
4) Ring terminal or fork (spade) terminal for a terminal block screw?
A ring terminal like the RA863 has to come off over the screw, which means backing the screw all the way out, but it cannot vibrate loose off the stud. A fork or spade terminal slides in sideways under a loosened screw, which is faster for service work on crowded blocks. For motor leads, grounding studs, and anything subject to vibration, use the ring; for frequently re-terminated control blocks, a fork is quicker.
5) Is the RA863 ring terminal copper, and can I use it on aluminum conductors?
The barrel is copper, so it is intended for copper conductors only. Aluminum wire needs a terminal rated AL or AL/CU with the appropriate inhibitor compound; putting a bare copper lug on aluminum invites galvanic corrosion at the joint.
6) Do I need a special crimper for the Sta-Kon RA863?
Use an insulated-terminal crimper with the red 22-16 AWG nest. Sta-Kon terminals are designed around a controlled-cycle or ratcheting crimp tool, and the UL listing under file E9809 applies to a properly made crimp. A general-purpose plier-style crimper will often under-form the barrel on 22 AWG and let the strand pull out.
7) Does the nylon insulation on the RA863 hold up better than vinyl?
The RA863 uses a nylon insulating sleeve rather than vinyl. Nylon is tougher against abrasion and splitting when the barrel is crimped, and it resists oils and solvents better, which is why it is the usual pick for machinery and automotive-style harnesses. The sleeve is red, matching the 22-16 AWG color code.
8) Is the RA863 made in the USA? I have a domestic sourcing requirement on this job.
Country of origin on the RA863 is the United States, which is what a government or federally funded project with domestic content language usually needs documented. The part number to cite on the submittal is Sta-Kon RA863.
