Sta-Kon RB4-TB – Frequently Asked Questions

1) What wire sizes does the Sta-Kon RB4-TB nylon insulated wire joint accept?
The RB4-TB handles 18-16 AWG conductors. The part is built around two No. 18 through two No. 16 wires, so it is a small-gauge joint for control, fixture, and low-current branch work rather than for 14 AWG or larger building wire.
2) What is a wire joint like the Sta-Kon RB4-TB actually used for versus a butt splice or a wire nut?
A wire joint gives you a terminating point for a group of wires all running in one direction, which is what you want when you are bundling several conductors into a single tap point in a panel or box. A butt splice joins two wires end to end from opposite directions, and a twist-on connector gives you no fixed, crimped body. Pick the RB4-TB when several same-direction conductors need to land together.
3) Is the Sta-Kon nylon wire joint UL listed for commercial and code work?
It carries UL file E9809, which is the listing inspectors look for on insulated terminations in commercial panels and junction boxes.
4) Is the Sta-Kon RB4-TB wire joint rated for 600 volt circuits?
Yes, 600V is the rating on the RB4-TB, which covers standard line-voltage branch circuits as well as low-voltage control wiring in panels and junction boxes.
5) Can this wire joint be used in a hot location like a fixture canopy or control cabinet?
Temperature capability runs to 221 F (105 C), so the nylon insulated wire joint holds up in warm enclosures such as ballast compartments, control panels, and luminaire canopies. It is not rated for anything above 105 C.
6) Which Sta-Kon part number should I order, and where is it made?
The part is Sta-Kon RB4-TB, made in the United States. Order by that MPN to get the 18-16 AWG white nylon insulated joint rather than one of the adjacent gauge ranges.
7) Why is the Sta-Kon RB4-TB white, and does the color mean anything electrically?
White here is the insulation color of the nylon body, used for identification and circuit organization in a panel. It does not denote a wire gauge or a neutral conductor by itself, so do not rely on the color alone to identify the conductor function.
8) Is the insulation on this Sta-Kon joint nylon or vinyl, and does that matter in a panel?
Nylon. Compared with vinyl, nylon insulation takes more mechanical abuse during pulling and crimping and resists cracking in tight panel bends, which is why it is the common choice for MRO and control panel terminations.
