Sta-Kon RB853M – Frequently Asked Questions
1) What wire sizes does the Sta-Kon RB853M ring terminal accept?
The RB853M takes 18 to 14 AWG stranded copper wire. Blue insulation is the standard color code for that range, which is how you spot it in a bin of mixed terminals without checking the stamp.
2) What stud or screw size does the RB853M ring fit?
The ring is sized for a No. 6 stud or screw, so it drops over a #6 terminal block screw or ground screw. If your panel lug is a #8 or 1/4-20, this ring will not pass over it and you need a larger ring size.
3) Is the Sta-Kon RB853M UL listed?
It carries UL file E9809. That is the detail an institutional or MRO inspector asks for when terminations are going into a listed panelboard assembly.
4) Should I use a ring terminal or a fork terminal on a terminal block?
Use the ring, like the RB853M, where the connection must not back off or pull free under vibration, since the screw has to come fully out before the wire can leave. A fork or spade slides out under a loosened screw, which makes it faster to service but a poor choice on automotive or harness work. The RB853M is a #6 ring for 18-14 AWG, so it suits panelboard, telecom, harness and automotive terminations.
5) Is the barrel on this ring terminal copper or aluminum?
Copper. That makes it a copper-only (Cu) termination for copper conductors, not a dual-rated AL/CU connector, so do not use it on aluminum building wire.
6) Does the nylon insulation on the RB853M hold up better than vinyl?
The sleeve is nylon rather than vinyl, which resists abrasion and splitting better when the terminal is pulled through a harness or flexed at a hinge point. It is an insulated terminal, so no separate boot or heat shrink is required to cover the barrel.
7) Are these Sta-Kon ring terminals made in the USA?
Country of origin is the United States, which matters if you are filling a government or federally funded order with domestic sourcing requirements.
