Sta-Kon RB873 – Frequently Asked Questions
1) What wire size does the Sta-Kon RB873 ring terminal take?
The RB873 is sized for 18 to 14 AWG stranded copper conductors, which is the range the blue insulation color codes for across the industry. If you are terminating 12 or 10 AWG, step up to a yellow-coded terminal instead; crimping oversized wire into this barrel will not give you a reliable connection.
2) What stud or screw size does the RB873 ring fit?
The ring tongue is drilled for a No. 10 stud or screw. It will also slip over a smaller 8-32 screw if you use a washer, but on anything larger than a No. 10 the ring will not pass over the stud.
3) Should I use a ring terminal like the RB873 or a fork terminal on a terminal block?
A ring terminal has to come off the stud entirely to be removed, which is exactly why you use it anywhere vibration or an accidental pull could back a connection out, motors, panels, battery and ground studs. A fork or spade terminal slides out from under a loosened screw and is faster to service, but it can work loose. For a No. 10 stud connection you want to stay put, the RB873 ring is the right choice.
4) Is the barrel on the RB873 copper, and does that matter for aluminum wire?
The terminal body is copper, so it is intended for copper conductors only. Aluminum building wire needs an AL9CU or AL-rated connector; putting bare aluminum into a copper barrel invites galvanic corrosion at the crimp.
5) Is the Sta-Kon RB873 made in the USA for a Buy American job?
Country of origin on the RB873 is the United States, which is what a government or federally funded procurement file will need to show for domestic sourcing.
6) What does the nylon insulation on the RB873 give me over a vinyl insulated terminal?
Nylon insulation is tougher than vinyl, it resists abrasion and cut-through when wires are pulled through a raceway or bundled tight in a panel, and it holds its shape better at elevated temperature. Visually it is still the standard blue for 18-14 AWG, so it drops straight into a color-coded kit.
7) What is the exact part number to order this blue No. 10 ring terminal?
Order it as Sta-Kon RB873. That is the manufacturer part number for the nylon insulated ring terminal, 18-14 AWG, No. 10 stud, blue.
