Sta-Kon 2RCS10X – Frequently Asked Questions
1) What wire gauge does the Sta-Kon 2RCS10X butt splice accept?
The 2RCS10X is sized for 12-10 AWG stranded copper wire. The yellow insulation is the standard color code for the 12-10 AWG range, so on a panel or harness you can identify it by color once installed. Running it on 14 AWG or smaller leaves the barrel oversized and the crimp unreliable, so step down to a 16-14 splice for those conductors.
2) Can I use a heat shrink butt splice like this on 277V or 480V lighting circuits?
The 2RCS10X carries a 600 V rating, which covers 120 V, 208 V, 277 V and 480 V branch circuits. For anything above 600 V you need a medium-voltage splice, not this part.
3) Do I need a heat gun, or can I just crimp this splice?
Both. A heat shrinkable butt splice is crimped first with the proper 12-10 AWG die, then heated so the sleeve shrinks down and the adhesive flows over the conductor insulation. Skipping the heat step leaves you with a bare crimp and no moisture seal. Neither a crimp tool nor a heat gun is supplied with the splice.
4) Is this butt splice OK for an engine compartment or a high-heat equipment room?
Yes. The 2RCS10X is rated to 150 C, which covers engine bays, boiler rooms, rooftop RTU wiring and motor junction boxes. Keep the conductor insulation rating in mind too, since the splice will outlast standard 90 C THHN jacket in sustained heat.
5) Should I use a heat shrink butt splice or a nylon-insulated one for outdoor or wet locations?
Use the heat shrink type. A standard nylon or vinyl insulated butt splice seals nothing; water wicks along the strands. The 2RCS10X shrinks down over the wire jacket and seals the ends, which is what you want for exterior lighting, irrigation, pump controls, below-grade pull boxes and wash-down areas. For a dry interior panel a nylon splice is adequate and faster since no heat is needed.
6) Is the Sta-Kon 2RCS10X splice barrel copper or aluminum?
Copper. That makes it suitable for copper conductors only, not for aluminum branch-circuit wiring, which needs a splice listed AL9CU with the proper inhibitor compound.
7) Is the Sta-Kon 2RCS10X made in the USA for a Buy American job?
Country of origin on the 2RCS10X is the United States, which is the data point procurement normally needs for Buy American or BABA documentation on federal, transit and institutional work.
8) What is the exact part number to order this Sta-Kon yellow 12-10 heat shrink splice?
Order it as Sta-Kon 2RCS10X. It is the yellow 12-10 AWG heat shrinkable butt splice, 1.6 length, rated 600 V and 150 C.
