Sta-Kon RB647 – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RB647 fork terminal crimp onto?
The RB647 fork terminal takes 18 to 14 AWG stranded copper wire. The blue insulation is the standard color code for that gauge band, so on a panel where you also run 22-16 (red) and 12-10 (yellow), the blue barrel tells the next tech what size wire is under it without pulling the terminal.
2) What screw size does the Sta-Kon RB647 fork terminal fit?
It is a No. 6 stud fork terminal, so it slips over a #6 screw or terminal stud. On a #8 or #10 terminal block screw the slot is too narrow to seat, and you would need the larger stud size instead.
3) Is the Sta-Kon RB647 terminal rated for 600 volt control and branch circuit wiring?
Yes, the RB647 carries a 600 V rating, which covers normal 120/208/240/277/480 V building and control wiring. It is also UL recognized under file E9809.
4) Can I use a fork terminal instead of a ring terminal on a control panel terminal block?
A fork (spade) terminal like the RB647 slides in under a loosened screw without removing it, which is why panel builders and electricians use them on terminal strips and device screws where getting the screw all the way out is a nuisance. A ring terminal is the better choice on a stud or bolt that carries vibration, or where a code or spec requires a captive connection, because the fork can back out if the screw loosens.
5) Is the barrel on the Sta-Kon RB647 copper or aluminum?
Copper. That makes it suitable for copper conductors only, not aluminum building wire, which needs a terminal specifically marked AL or AL/CU.
6) Is the Sta-Kon RB647 made in the USA for a government or institutional spec job?
Country of origin on the RB647 fork terminal is the United States, which is the detail most often requested on federal, education, and healthcare procurement paperwork. UL file E9809 is the other number those submittals usually ask for.
7) Does the vinyl insulation on the RB647 fork terminal need separate heat shrink or tape?
No. The insulation is pre-applied vinyl over the barrel, so once it is crimped the conductor is already covered up to the tongue. Vinyl is a general purpose insulation, not a high temperature one, so for engine compartments or other hot locations choose a nylon or heat shrink insulated terminal instead.
