Sta-Kon RB877 – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RB877 ring terminal crimp onto?
The RB877 takes 18 to 14 AWG stranded or solid copper wire. The blue vinyl insulation is the standard color code for that 16-14 AWG band, so if you are working a panel with mixed terminals, blue tells you at a glance it is the mid-size barrel and not the red 22-18 or yellow 12-10.
2) What stud or screw size does the RB877 ring terminal fit?
It is sized for a No. 10 stud or screw. The closed ring will not slip off a loosened terminal screw the way a fork or spade tongue will, which is why ring terminals are specified for vibration-prone equipment and motor connections.
3) Is this ring terminal rated for 600 volt control and branch circuit work?
Yes, 600 V. That covers standard 120/208/240/480 V control panels, motor leads, and branch circuit terminations. It also carries UL file E9809.
4) Should I use a ring terminal or a fork terminal on a No. 10 terminal screw?
Use the ring where the screw cannot be fully removed from service without the wire coming off, which is the point: the RB877's closed ring stays captive. A fork or spade tongue slides out sideways under a backed-off screw, which makes it faster to service but a poor choice on equipment that vibrates. Both land on a No. 10 stud; the decision is captive versus quick-disconnect.
5) Is the RB877 terminal copper or aluminum, and can I put it on aluminum wire?
The barrel is copper, so it is for copper conductors only. Aluminum building wire needs a terminal marked AL or AL9CU with the appropriate inhibitor compound; a copper-only barrel on aluminum invites galvanic corrosion and a hot joint.
6) Do I need a special crimp tool for Sta-Kon insulated ring terminals?
Crimp it with an insulated-terminal crimper in the blue 16-14 AWG nest. Pliers or a bare-terminal die will crush the vinyl sleeve and leave an unreliable barrel crimp. The vinyl insulation also means no separate heat shrink or tape is needed over the barrel.
7) Is the Sta-Kon RB877 made in the USA?
Yes. Country of origin is the United States, which is what agencies and institutional buyers working under domestic-sourcing requirements need on the submittal.
8) What is the exact part number to reorder this blue ring terminal?
Order Sta-Kon RB877. That one number covers the full description: vinyl insulated ring tongue, 18-14 AWG, No. 10 stud, blue.
