Sta-Kon RJ737 – Frequently Asked Questions
1) What wire size does the Sta-Kon RJ737 ring terminal take?
The RJ737 is sized for 2/0 AWG conductor. It is a single-size barrel, so it will not grip smaller gauge wire properly, and 2/0 is the only conductor it is rated to crimp. If your cable is 1/0 or 3/0, you need the matching terminal for that gauge instead.
2) Can I use this ring terminal on a 480V motor feeder?
The RJ737 carries a 600 V rating, so 480 V three phase feeder work is within its rating. It is also UL recognized under file E9809, which is what most inspectors and spec writers want to see on a terminal in a panel or motor connection box.
3) Will this terminal work with aluminum cable?
No. The barrel on the RJ737 is copper, so it is for copper conductor only. Aluminum needs a terminal listed AL or AL/CU with the appropriate inhibitor compound; crimping aluminum into a copper-only barrel creates a dissimilar metal connection.
4) Is the blue insulation on this Sta-Kon terminal just a color, or does it mean something?
Blue on the RJ737 is the manufacturer's color coding for the barrel size, not a decorative choice. Color is how an electrician confirms on sight that the terminal matches the conductor, and here blue goes with the 2/0 AWG barrel. The sleeve itself is nylon insulation over a copper barrel.
5) Do I need a special crimper for a 2/0 nylon insulated ring terminal?
Yes. At 2/0 AWG a hand-squeeze insulated terminal plier will not develop enough force. A 2/0 barrel needs a heavy duty crimper, typically a hydraulic or large mechanical tool with the die matched to the barrel size. The nylon sleeve on the RJ737 is crimped through along with the barrel, so use the insulated-terminal die position rather than a bare lug die.
6) Why pick a nylon insulated ring terminal instead of a bare compression lug?
A nylon insulated ring terminal like the RJ737 arrives with the sleeve already on, so you are not cutting and shrinking heat shrink over a bare lug barrel after the crimp. Nylon also takes abrasion and flexing better than vinyl, which matters where the cable gets moved. Pick a bare lug instead when you need to double-crimp, when the landing is tight on space, or when you are heat shrinking the whole termination to a specific color code yourself.
7) Is a ring terminal or a fork terminal better for a 2/0 feeder landing?
Use the ring, which is what the RJ737 is. A ring tongue is closed, so it cannot vibrate off a 3/8 inch stud if the nut backs off, and that is the accepted choice on power connections. Fork and spade terminals exist for quick-disconnect low current work on small gauge control wire, not for 2/0 conductor at 600 V.
8) What part number do I order and where is this Sta-Kon terminal made?
Order Sta-Kon part number RJ737. It is manufactured in Mexico.
