Sta-Kon RA877 – Frequently Asked Questions
1) What wire sizes does the Sta-Kon RA877 ring terminal crimp onto?
The RA877 is sized for 22 to 16 AWG stranded conductor. That red insulation is the standard color code for the 22-16 AWG range, so on a panel where blue barrels are 16-14 and yellow are 12-10, red tells the next tech what gauge went in without pulling the wire. Anything larger than 16 AWG will not seat in the barrel, and a 14 AWG lead crimped into it is a connection that will back out.
2) What size stud or screw does the RA877 ring fit?
The ring on the Sta-Kon RA877 is drilled for a No. 10 stud or screw. That covers the typical 10-32 terminal screw on motor starters, contactor terminal blocks, and ground lugs. For a 1/4-20 stud you need a larger ring; a No. 10 ring will not pass over it.
3) Is the RA877 ring terminal rated for 600 volt control and power circuits?
Yes, it carries a 600 V rating, which covers 480Y/277 and 208Y/120 control and branch circuit work. It is also built under UL file E9809.
4) Should I use a ring terminal or a fork terminal on a motor starter?
Use the ring, like the RA877, anywhere the connection takes vibration or where a loosened screw must not release the wire. The ring is captive, so the conductor stays on the stud even if the screw backs off a turn. A fork or spade terminal slides out from under a loosened screw, which is why most equipment specs and inspectors want rings on motor, pump, and rooftop equipment terminations. Forks are worth it only where you cannot remove the screw to land the wire.
5) Is the RA877 terminal barrel copper or aluminum?
Copper, with a vinyl insulating sleeve over the barrel. Copper conductor only, then. It is not a dual-rated AL/CU terminal, so do not land aluminum conductor in it.
6) Do I need a special crimper for Sta-Kon RA877 insulated ring terminals?
It needs an insulated-terminal crimp die matched to the 22-16 AWG color code, which on most tools is the red nest or the red-marked station. A plain non-insulated crimp jaw will cut the vinyl sleeve instead of compressing the barrel through it, and pliers will not give you a sound termination at all. Sta-Kon terminals are designed around Sta-Kon tooling, so the die marked for red 22-16 is the one to reach for.
7) Is the Sta-Kon RA877 made in the USA for Buy American jobs?
Country of origin on the RA877 is the United States, which matters on federally funded and Buy American Act work where domestic content has to be documented for the submittal package.
8) What is the exact part number to reorder these red ring terminals?
Order Sta-Kon RA877. That is the manufacturer part number for the vinyl insulated, 22-16 AWG, No. 10 stud ring terminal in red.
