Sta-Kon RC337-250 – Frequently Asked Questions
1) What wire size does the Sta-Kon RC337-250 ring terminal take?
The RC337-250 is built for 12-10 AWG conductor. The yellow insulation is the color code that tells you that at a glance on a crowded panel, so crews can sort 12-10 terminals from the red and blue sizes without reading the barrel.
2) Is this ring terminal rated for 600 volt control and branch circuit work?
Yes, the RC337-250 carries a 600 V rating, which covers typical commercial control panel, lighting and branch circuit terminations. It is UL recognized under file E9809.
3) Should I use a ring terminal or a fork terminal on a panel terminal block?
A ring terminal like the RC337-250 has a closed barrel end that cannot vibrate off the stud, which is why it is the one specified for grounding, motor leads and anything subject to movement. A fork or spade slides out from under a loosened screw, so use it only where you need fast disconnects and the screw stays captive. Both land on the same #6 hardware.
4) Is the barrel on this Sta-Kon terminal copper or aluminum?
Copper. That means it is intended for copper conductor, not aluminum building wire, which needs a terminal marked AL or AL/CU with the proper inhibitor compound.
5) Is this a crimp terminal or does it need solder?
The RC337-250 is a crimp terminal with vinyl insulation over the barrel. You strip the 12-10 AWG conductor, insert to the barrel stop, and crimp with a die matched to the yellow 12-10 color code. No solder, no heat, and the vinyl sleeve is not heat shrink so do not put a torch near it.
6) Are these Sta-Kon ring terminals made in the USA for government and institutional orders?
Country of origin on the RC337-250 is the United States, which is what a government, healthcare or education procurement file usually needs documented alongside the UL E9809 listing.
7) What is the exact Sta-Kon part number I should order for a yellow 12-10 AWG #6 ring terminal?
Order Sta-Kon RC337-250. That is the manufacturer part number for the vinyl insulated ring terminal in 12-10 AWG with the No. 6 ring, yellow.
