Sta-Kon RC737-250 – Frequently Asked Questions
1) What wire size does the Sta-Kon RC737-250 ring terminal take?
The RC737-250 is sized for 12-10 AWG stranded copper wire, and the yellow vinyl insulation is the standard color code for that range. If your conductor is 16-14 AWG you need a blue-insulated terminal instead, and 22-16 AWG takes a red one.
2) Will the Sta-Kon RC737-250 fit a 3/8 inch stud or bolt?
Yes. The ring tongue on the RC737-250 is a 3/8 stud size, so it lands on a 3/8 inch terminal stud, breaker lug screw, or ground bolt. For a 1/4 or 5/16 stud you want a smaller tongue so the ring can't rotate and bridge to an adjacent terminal.
3) Can I use this insulated ring terminal on 480 V equipment?
The ring terminal is rated 600 V, so it covers 120/208, 277, and 480 V circuits inside panels, controls, and motor connections.
4) Is the Sta-Kon RC737-250 UL listed for inspected work?
It carries UL file E9809. That is the detail an inspector or spec writer asks for on terminations in listed assemblies. It is also made in the United States, which matters on Buy American and federal procurement jobs.
5) Is this ring terminal copper or aluminum, and can I put it on aluminum wire?
The barrel is copper, so it is intended for copper conductors. Aluminum feeders need a terminal marked AL or AL9CU with the appropriate compound, not a copper crimp barrel.
6) Should I use a ring terminal or a fork terminal on a panel stud?
A ring like the RC737-250 has to be slipped over the stud with the nut fully removed, but once torqued it cannot vibrate or pull off sideways. A fork (spade) terminal slides in under a loosened screw, which is faster for service work, but it can back out. Use the ring on vibration-prone or safety-critical connections such as grounds and motor leads.
7) Do I need a special crimp tool for the Sta-Kon RC737-250?
It is a nylon/vinyl insulated barrel in the 12-10 AWG range, so crimp it with the yellow-coded nest of a standard insulated-terminal crimper. The terminal itself is the complete termination; no separate insulating sleeve is required since the vinyl insulation is already on the barrel.
