Sta-Kon RB480 – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RB480 ring terminal crimp onto?
The RB480 takes 16 to 14 AWG stranded copper wire. The blue insulation is the standard color code for that range, so a tech can spot it in a bin without reading the barrel. Anything 12 AWG or larger needs a different terminal.
2) What stud or screw size does the RB480 ring fit?
It is sized for a No. 8 stud or screw. The ring tongue slips over a #8 terminal screw or bolt, which covers most control panel terminal blocks, ground screws, and appliance lugs.
3) Why pick a ring terminal instead of a fork or spade for a terminal block?
A ring tongue, like the one on the RB480, is a closed barrel of copper that cannot slip off if the screw backs out under vibration. A fork or spade pushes in without removing the screw, which is faster for service work but will walk off a loose screw. For motor leads, panel grounds, and anything that vibrates, the ring is the one to use.
4) What is the difference between a rectangular ring terminal and a standard round one?
The RB480 has a rectangular tongue rather than a round one. The flat sides let the terminal sit between adjacent screws on a crowded terminal strip without the tongue edges contacting the neighboring pole, and the squared profile resists rotation under the screw head. Electrically it lands the same as a round ring on a #8 stud.
5) Is the Sta-Kon RB480 made in the USA for a government or Buy American job?
Country of origin on the RB480 is the United States. That is the fact a federal, state, or institutional procurement office needs for a domestic-content line item, alongside the UL E9809 file number.
6) Is nylon insulation on the RB480 better than vinyl for hot locations?
Nylon is the tougher of the two. The RB480 uses a nylon insulated sleeve, which holds up to abrasion and pull-through better than vinyl and resists cracking when the wire bundle is flexed or dressed tight in a panel. That is the usual reason a spec calls out nylon over vinyl on the same 16-14 AWG range.
7) Do I need a special crimper for the RB480 terminal?
Use a crimp tool matched to the insulated 16-14 AWG range, which is the blue die position or blue-marked nest on most insulated terminal crimpers. The nylon sleeve is crimped along with the copper barrel, so a bare-terminal die will cut the insulation rather than form it.
