Sta-Kon RE757 – Frequently Asked Questions
1) What wire size does the Sta-Kon RE757 ring terminal take?
The RE757 is sized for 6 AWG conductor. It is a nylon insulated ring terminal with a copper barrel, so it crimps onto 6 AWG stranded copper wire. Blue is the color code on this one, which on Sta-Kon nylon terminals follows the wire size rather than the stud size.
2) Is this ring terminal rated for 600 volt circuits?
The RE757 carries a 600 V rating and is UL recognized under file E9809. That covers typical commercial branch circuit and panel work up to 600 V. Confirm the terminal block or device you are landing on is also rated for the application voltage.
3) Ring terminal or fork (spade) terminal for a 6 AWG motor connection?
Use the ring. A fork terminal can slip off the stud if the nut backs off, which is why ring terminals like the RE757 are the choice on motor leads, panel grounds, and anything subject to vibration. Fork terminals only make sense where you need to drop the wire off a screw without removing the screw entirely.
4) Do I need a special crimp tool for a 6 AWG Sta-Kon ring terminal?
At 6 AWG you are past the range of a standard hand crimper for small insulated terminals. A 6 AWG barrel needs a heavy-duty ratcheting or hydraulic crimper with the correct die nest for that size. A crimp made with an undersized tool will pull out under load, so match the tool to the 6 AWG barrel.
5) Can I use this terminal on aluminum wire?
No. The RE757 barrel is copper and is intended for copper conductors. Aluminum conductors need a terminal rated AL/CU with the appropriate inhibitor compound; putting aluminum in a copper-only barrel invites galvanic corrosion and a failed connection.
6) Does the nylon insulation on the RE757 hold up better than vinyl?
Nylon insulation resists abrasion, cut-through, and cold cracking better than vinyl, and it tolerates higher temperatures, which is why it is specified for panel and machine wiring where conductors get pulled through tight raceways. The RE757 is nylon insulated with a copper barrel underneath.
7) Is the Sta-Kon RE757 made in the USA, and what is the part number to order?
Order it as Sta-Kon RE757. Country of origin is the United States.
