Sta-Kon C77M – Frequently Asked Questions
1) What wire size does the Sta-Kon C77M ring terminal accept?
The C77M is sized for 12-10 AWG conductors. If you are terminating 14 or 16 AWG, this barrel is too large to crimp reliably and you need a smaller terminal in that range.
2) Is the Sta-Kon C77M insulated or bare?
Bare. It's a non-insulated copper ring terminal, so the crimped barrel is exposed. If the connection sits in a panel where you need the barrel covered, add heat shrink or sleeving, or choose an insulated ring terminal of the same 12-10 AWG range.
3) Is the C77M terminal UL listed?
It carries UL file E9809. That is the detail an institutional or MRO inspector asks for when the terminations have to be a listed component in a control panel or equipment build.
4) Can I use a ring terminal like the C77M on an aluminum conductor?
No. The C77M barrel is copper and is intended for copper conductors in the 12-10 AWG range. Aluminum conductors require a terminal rated AL or AL9CU to avoid a dissimilar metal connection.
5) Should I use a ring terminal or a fork terminal on my terminal strip?
A ring terminal like the C77M has to come off the stud entirely to be removed, which is why it is used where vibration or a loosening screw could drop the connection. A fork or spade slides out sideways under a loosened screw, which is faster to service but less secure. Pick the ring for motor, ground, and equipment studs; pick the fork for strips you expect to re-terminate often.
6) Why does the C77M come on Mylar tape instead of loose in a bag?
The C77M is supplied on Mylar tape, which is the strip format fed into a bench or automatic crimping machine. For hand crimping with a loose tool, a strip-mounted terminal still works but you break the terminals off the carrier one at a time.
7) Where is the Sta-Kon C77M made?
The C77M is manufactured in the United States, which matters on government and institutional jobs carrying domestic sourcing requirements.
