Sta-Kon RB657-200 – Frequently Asked Questions
1) What wire sizes does the Sta-Kon RB657-200 fork terminal crimp?
The RB657-200 is sized for 18 to 14 AWG stranded copper conductors. That is the blue insulation color band, which is the standard trade code for the 16-14 AWG range on insulated terminals, so if you are terminating 12 AWG you need a yellow-coded terminal instead.
2) What screw size does this blue fork terminal fit?
It is a No. 8 stud fork terminal, so it slips onto a #8 screw or stud on a terminal block, breaker, or device. The fork (spade) tongue means you can slide it under a loosened screw without pulling the screw all the way out, which is why electricians favor them for terminal strips and control panel work over ring tongues.
3) Is a fork terminal or a ring terminal better for a control panel terminal strip?
Fork terminals like the RB657-200 are the usual choice on terminal strips and panel devices because the open tongue lets you back the #8 screw out only part way and slide the connector in, which makes service and rewiring much faster. Ring terminals are the safer pick where vibration or accidental tug-out is a concern, since the closed tongue cannot escape the screw. For battery posts and grounding studs, go with a ring.
4) What voltage is the Sta-Kon RB657-200 rated for?
600 V. That covers standard commercial and industrial control circuits, 120/208, 277, and 480 V panel wiring, and low-voltage DC work. It is UL recognized under file E9809.
5) Is this terminal UL listed for inspected commercial work?
The terminal carries UL file E9809 and a 600 V rating, so it is acceptable for the inspected 600 V and under work that MRO and institutional specs usually call out. Install it with the matching crimp tool die for the 18-14 AWG range, since an uncontrolled crimp is the usual reason a terminated conductor fails inspection.
6) Is the barrel on this fork terminal copper or aluminum?
Copper. That means it pairs with copper conductors only, which is what the 18-14 AWG stranded building and control wire you will be landing on it is. Do not use it on aluminum conductors, which need a dual-rated AL/CU connector with the proper inhibitor compound.
7) Is the Sta-Kon RB657-200 made in the USA?
Yes, country of origin is the United States, which matters if you are buying against a Buy American or domestic-preference requirement on a government or institutional job.
8) What is the exact part number to order this blue No. 8 fork terminal?
Sta-Kon RB657-200. It is the expanded-barrel vinyl insulated fork terminal for 18-14 AWG on a No. 8 stud.
