Sta-Kon RM9751 – Frequently Asked Questions
1) What wire size does the Sta-Kon RM9751 ring terminal take?
The RM9751 is sized for 4/0 AWG conductor. It is a one-size barrel, so it will not grip smaller gauges reliably, even with multiple crimps. If you are terminating 2/0 or 1/0 feeders, step down to the terminal built for that gauge rather than filling the 4/0 barrel.
2) Is this ring terminal copper, and can I use it on aluminum conductors?
The barrel is copper, so it is intended for copper conductors. Copper-only terminations should not be used on aluminum wire; aluminum feeders need an AL/CU rated connector instead.
3) Is the RM9751 rated for 600 volt circuits?
The insulation on this Sta-Kon ring terminal is rated 600 V, which covers standard commercial and industrial branch and feeder work up to 600 volt systems. It also carries a UL file listing under E9809.
4) Why choose a nylon insulated ring terminal over a spade or fork terminal on a 4/0 feeder?
A ring tongue is a closed barrel: it cannot vibrate off the stud if the nut backs off, which is why it is the normal choice for 4/0 feeder and ground connections on switchgear, motors, and generator sets. A spade or fork terminal is for fast service where you want to pull the lead off without removing the nut, and it is a poor choice on heavy conductors under vibration. The nylon sleeve on the RM9751 also gives it more abrasion and flex resistance than a vinyl sleeve of the same rating.
5) Do I need a special crimp tool for the Sta-Kon RM9751?
Yes. At 4/0 AWG this is a heavy-barrel lug, well past the range of a hand-squeeze insulated terminal plier. It needs a hydraulic or large mechanical crimper with the die for 4/0 copper. Plan the tooling in with the order if your crew only carries small-gauge crimpers.
6) What does the blue color on this Sta-Kon terminal mean?
Blue here is the insulation color on the nylon sleeve of the RM9751, matching the 4/0 AWG size it accepts. Color coding on insulated terminals is a quick field check that the barrel matches the conductor, which is useful when an electrician is pulling terminals out of a bin on a panel build.
7) Where is the Sta-Kon RM9751 made?
Country of origin on the RM9751 is Mexico. That matters on government and institutional jobs that carry domestic-sourcing language, so check it against your procurement requirement before specifying.
