Sta-Kon RB484 INSNYL RECT RNG TERM 16-14 No6 BLUE

The RB484 is sized for 16-14 AWG stranded copper wire, which is why the insulation is blue. Blue is the standard color code for the 16-14 range on nylon and vinyl insulated terminals, so if you are matching an existing harness, blue barrels on the other conductors mean you are in the right size. For 22-18 AWG you need a red terminal instead, and for 12-10 AWG a yellow one.

It takes a No. 6 stud or screw. That is the terminal strip and small-screw size you find on thermostats, control boards, relay bases and appliance terminal blocks. If the screw on your block is a 10-32 or a 1/4-20, this tongue is too small and you need a larger stud size in the same 16-14 blue range.

Yes, the terminal carries a 600 V rating, which covers standard commercial control wiring, motor control panels and 120/208/240/480 V branch circuits. It is also UL recognized under file E9809, so it will satisfy an inspector looking for a listed termination on a panel build.

Both are closed-tongue terminals, so the connection cannot slip off the stud the way a fork or spade can. The rectangular tongue on the RB484 is narrower across the shoulders than a round ring of the same stud size, which lets it sit between crowded terminal block screws without shorting against the neighboring conductor. Use a round ring where there is room and you want maximum bearing area under the screw head; use a rectangular tongue like this one on tight-pitch terminal strips. If you need to pull a wire off for service without loosening the screw fully, a spade or flanged fork is the better choice, but it is less secure against vibration.

Nylon. Nylon insulated barrels handle higher temperatures and resist abrasion and crushing better than PVC/vinyl, which is why they are specified for motor control centers, machine panels and enclosures that run warm. Nylon also resists splitting when the barrel is crimped, so the insulation support stays intact on the finished termination.

Country of origin on the RB484 is the United States, which is what a government, institutional or federally funded project needs on its submittal for electrical terminations. The barrel is copper.

No. The RB484 barrel is copper and sized for 16-14 AWG copper conductors. Aluminum requires a terminal specifically rated AL or AL/CU with the proper inhibitor compound, so do not substitute this one on an aluminum feeder or branch conductor.

Use a controlled-cycle or ratcheting crimp tool set up for insulated terminals in the 16-14 AWG range, and match the die to the blue color code. A pliers-style hardware store crimper will deform the nylon and leave an under-compressed barrel that fails a pull test. Strip the conductor only as far as the barrel depth so no bare copper shows past the insulation support.
