Sta-Kon RBB25 – Frequently Asked Questions
1) What wire size does the Sta-Kon RBB25 parallel splice take?
The RBB25 is sized for 18-16 AWG stranded copper wire, which is why it comes in blue (the standard color code for the 16-14/18-16 range on nylon insulated terminals). Both conductors going into the splice must fall in that range; step up to a yellow-coded splice for 12-10 AWG or down to a red one for 22-18.
2) Can I use this splice on a 277V or 480V circuit?
The RBB25 carries a 600 V rating, so it is good for 120, 208, 240, 277 and 480 V building circuits. Insulation temperature rating is 105 C.
3) Is the Sta-Kon RBB25 UL listed for a commercial inspection?
It is covered under UL file E9809. Paired with the 600 V and 105 C ratings, that is what an inspector or facility electrician is usually looking for on an insulated splice in a fixture whip or control panel.
4) What is a parallel splice and when should I use one instead of a butt splice?
A parallel splice takes both conductors in from the same end and runs them side by side, so the finished joint doubles back rather than running straight through. Use it for taps and pigtails where both wires come from the same direction, such as adding a leg off a fixture whip. If the two wires approach from opposite directions and you want an in-line joint, use a butt splice instead. The RBB25 is the nylon insulated parallel type for 18-16 AWG.
5) Do I need a special crimper for the Sta-Kon RBB25?
Yes, it is a crimp-only barrel, so it needs a ratcheting or plier-type crimp tool with the die for insulated 18-16 AWG terminals (the blue nest). Nylon insulation will not take a solder or set-screw connection, and a pliers squeeze will not give a reliable joint at 600 V.
6) How long is the RBB25 splice body?
Overall length is 0.84 inch. Worth checking against the space you have if you are splicing inside a small fixture canopy or a crowded panel, since a parallel splice folds the second conductor back alongside the first and needs a bit of room beyond the barrel.
7) Is nylon insulation better than vinyl for the splice I am installing?
Nylon takes abrasion and pull-through better than vinyl and holds up at higher heat, which is why this one is rated to 105 C. For fixture whips, motor leads and anywhere the harness gets dragged through conduit or a raceway, the nylon body is the one to specify.
8) Is the Sta-Kon RBB25 made in the USA?
Country of origin is the United States, which matters if you are buying against a Buy American or domestic-preference requirement on a government, school or healthcare project. The MPN to put on the submittal is RBB25.
