Sta-Kon RCC217-250 – Frequently Asked Questions
1) What wire gauge does the Sta-Kon RCC217-250 butt splice accept?
The RCC217-250 is sized for 12-10 AWG wire, and the yellow insulation is the standard color code for that range. Both ends take the same 12-10 range, so it joins two conductors of like size end to end. For 16-14 AWG you need a blue-coded splice, and for 22-18 a red one.
2) Is the Sta-Kon RCC217-250 butt splice UL listed for inspected work?
It carries UL file E9809, which is the listing an inspector looks for on an insulated splice used in a 600 V premises circuit. Keep in mind a crimped butt splice is only code-compliant when it is installed with the matching crimp tool and enclosed per the wiring method.
3) Will this splice hold up inside a hot luminaire or near a rooftop unit?
The vinyl insulation on the RCC217-250 is rated to 105 degrees C, so it is suitable for fixture whips, ballast compartments, and HVAC control wiring within that limit. Above 105 C you want a high-temperature nylon or heat-shrink insulated splice instead.
4) Do I need a special crimper for a vinyl insulated butt splice, or will pliers work?
Use an insulated-terminal crimp tool with the yellow 12-10 nest. The RCC217-250 has a copper barrel under the vinyl sleeve, and pliers or a bare-terminal die will crush the insulation without forming a proper barrel crimp, which is how these pull out later. One crimp per end, with a tug test after each.
5) Is a butt splice a better choice than a wire nut for extending a run?
For an inline extension of two conductors a butt splice like the RCC217-250 gives a low-profile crimped joint that fits where a wire nut will not, such as inside a fixture canopy, a control panel wire bundle, or a whip. A wire nut is the better pick when you are joining three or more conductors or want a reusable connection, since a crimped splice is one-time.
6) Is the conductor in this splice copper or aluminum?
Copper barrel with a vinyl insulating sleeve over it. That means it is intended for copper conductors; aluminum wire needs a connector specifically listed AL9CU with the required inhibitor compound.
7) Are Sta-Kon RCC217-250 splices made in the USA for a government or institutional spec?
Country of origin is the United States, which is what domestic-preference procurement on federal, education, and healthcare jobs generally asks you to document. The part number to cite on the submittal is RCC217-250.
