Sta-Kon RA484 INS NYL RECT RNG TERM 16-14 No6 RED

The RA484 is built for a No. 6 stud, so it drops over a #6 screw or terminal post. If your terminal block or ground screw is a #8 or #10, this tongue won't go over it and you need a larger ring size.

Yes. The RA484 nylon insulated ring terminal is rated 600 V, which covers 120V, 277V and 480V control and power terminations.

It carries UL file E9809. That matters for panel work and inspected installs where terminations have to be a listed component.

The barrel is copper with a nylon insulating sleeve, so it is for copper conductors only. Terminating aluminum wire in a copper-only barrel invites galvanic corrosion and a hot joint; use a terminal marked AL/CU or AL for aluminum.

A rectangular ring tongue is closed, so the conductor cannot pull off the stud if the nut backs off slightly. A fork or spade tongue is open and slides out sideways, which is faster to service but not acceptable where vibration or a code requirement calls for a captive connection. Pick the RA484 style ring for motor leads, grounds and anything that moves; pick a fork where you expect to pull the wire often.

Red is the insulation color on this terminal. On insulated crimp terminals the sleeve color identifies the wire range the barrel is sized for, so crews use it to sort terminals on the bench and to match the right crimp die nest without reading the stamp.

Country of origin is the United States, which is what government, transit and other Buy American jobs typically need documented on electrical components.

It is a crimp terminal, not a solder or screw type, so it needs an insulated-terminal crimper with the correct die nest for the barrel. A general purpose pliers-style crimper will deform the nylon sleeve and under-form the barrel, which is the usual cause of a termination that reads fine cold and fails under load.
