Sta-Kon RA77 – Frequently Asked Questions
1) What wire size does the Sta-Kon RA77 ring terminal take?
The RA77 is sized for 22 to 16 AWG stranded copper wire, and the red insulation is the standard color code for that range. If your conductor is 14 AWG or larger, this is the wrong terminal - step up to the blue (16-14) or yellow (12-10) body size.
2) What stud or screw size does the Sta-Kon RA77 ring fit?
The ring tongue is drilled for a No. 4 stud or screw, so it slips over a #4 machine screw or terminal block stud. On a larger stud, say a #10 or 1/4-20, the ring will not pass over it and you need a bigger tongue size.
3) Can I use the RA77 ring terminal on a 480V control circuit?
The vinyl insulation on the RA77 is rated 600 V, so it covers 480V and 277V control and power terminations as well as ordinary 120/240V work. It also carries a UL file listing, E9809.
4) Is the Sta-Kon RA77 terminal barrel copper or aluminum?
Copper. That makes it a match for stranded copper conductors, which is what 22-16 AWG control and appliance wiring normally is. It is not an AL/CU rated lug and should not be crimped onto aluminum conductors.
5) Why choose a ring terminal like the RA77 instead of a spade or fork terminal?
A ring tongue has to have the screw backed all the way out to install, but it cannot vibrate off once the screw is tightened. Fork terminals slide in under a loosened screw and save time, which is why panel shops use them, but on motor leads, equipment grounds, and anything subject to vibration the closed ring is the one that stays put. The RA77 is the #4 stud version for 22-16 AWG wire.
6) What crimp tool do I need for Sta-Kon RA77 red insulated ring terminals?
Use an insulated-terminal crimper set to the red 22-16 AWG die nest. Crimping a red barrel in the blue or yellow nest leaves the connection loose. Strip the conductor so the strands just reach through the barrel and crimp over the metal sleeve, not the vinyl skirt.
7) Is the Sta-Kon RA77 made in the USA?
Country of origin on the RA77 vinyl insulated ring terminal is the United States, which matters if you are filling a government, federal facility, or Buy American specified MRO order.
8) How do I order the exact Sta-Kon ring terminal I already have in stock?
Order by manufacturer part number RA77. That single number pins the whole configuration: vinyl insulated ring, red body for 22-16 AWG, No. 4 stud tongue. There are no finish or size options to specify alongside it.
