Sta-Kon RBB25-EU – Frequently Asked Questions
1) What is a Sta-Kon RBB25-EU butt splice used for?
It is an insulated butt splice, the connector you crimp over the stripped ends of two wires to join them end to end in a single straight run. Unlike a ring or fork terminal, there is no stud or screw connection here, so it is for wire-to-wire splicing rather than landing a conductor on a terminal block.
2) What is the insulation on the Sta-Kon RBB25-EU splice made of?
Polycarbonate. That is a rigid, harder-wearing insulation than the soft vinyl used on many general purpose crimp splices, which is what you want where the splice may be handled, pulled through a raceway, or exposed to abrasion in a panel or junction box.
3) Can I install the Sta-Kon RBB25-EU splice with pliers, or do I need a crimp tool?
Use a proper crimping tool. An insulated butt splice relies on a controlled, full-circumference crimp on each barrel end to make a mechanically sound and low-resistance joint; squeezing it with pliers deforms the barrel unevenly and leaves a connection that can loosen or heat up. The polycarbonate body also will not tolerate being mashed the way soft vinyl does.
4) Is a polycarbonate butt splice the right choice, or should I use a wire nut or heat shrink splice?
A crimped butt splice like the Sta-Kon RBB25-EU keeps two conductors in a straight, low-profile inline joint, which is what you want inside conduit bodies, control panels, and tight raceways where a twist-on wire nut would not fit and would not hold up to vibration. Wire nuts are for junction boxes with multiple conductors pigtailed together. If the splice will sit in a wet or outdoor location, an adhesive-lined heat shrink splice is the better pick, since polycarbonate insulation is a mechanical barrier, not a moisture seal.
5) What part number do I order for the Sta-Kon polycarbonate butt splice, and where is it made?
Order it by manufacturer part number RBB25-EU, brand Sta-Kon. Country of origin is Sweden, which matters if you are filling a government or institutional order with origin reporting requirements.
