Sta-Kon RBC727 – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RBC727 ring terminal accept?
The RBC727 is sized for 16 to 14 AWG stranded copper wire. That's the blue color code on insulated terminals, so if the barrel on the terminal you're replacing is blue, you're in the right range. Anything heavier (12-10 AWG) or lighter (22-18 AWG) needs a different terminal, since over-crimping a 12 AWG conductor into a 16-14 barrel won't hold mechanically.
2) Is the Sta-Kon RBC727 rated for 600 volt circuits?
Rated 600 V, and UL recognized under file E9809. That covers standard commercial and industrial branch circuits, control panels, and motor connections at 600 V and below.
3) What is the difference between a heavy-duty vinyl insulated ring terminal and a standard one?
The RBC727 is a heavy-duty build: a thicker copper barrel than a standard-duty terminal of the same 16-14 AWG range, with the same vinyl insulating sleeve over it. Panel builders and MRO crews specify heavy-duty where the connection sees vibration or repeated service, because the heavier barrel tolerates crimping and handling better. For a light, low-vibration control connection, a standard-duty terminal in the same wire range does the same electrical job.
4) Should I use a ring terminal or a fork terminal on a terminal block?
A ring terminal like the RBC727 has to come off the stud entirely to be removed, which is exactly why it's used where a connection must not shake loose: motor terminals, grounding studs, bus bars, vibrating equipment. A fork or spade terminal slides out sideways under a loosened screw, which is faster for service work on terminal strips but can back out under vibration. If the connection is safety or ground related, use the ring.
5) Is the RBC727 terminal copper or aluminum, and can I put it on aluminum wire?
The barrel is copper, so it is intended for copper conductors. Crimping copper terminals onto aluminum wire creates a dissimilar-metal joint that corrodes and loosens over time; aluminum conductors need a terminal specifically rated AL or AL/CU.
6) Is the Sta-Kon RBC727 made in the USA?
Country of origin is the United States. That matters on federal, state, and institutional work where domestic-sourcing provisions apply to electrical components.
7) What is the Sta-Kon part number I should order for a 16-14 AWG, 5/16 inch ring terminal?
Sta-Kon RBC727 is the manufacturer part number for the vinyl insulated heavy-duty ring terminal in 16-14 AWG with a 5/16 inch ring. Order by RBC727 and the wire range, ring size, blue insulation, and 600 V rating all follow from it.
