Sta-Kon 2RC10XCP EXP INS VNY BTT SPLC, 12-10, MINIPK

The 2RC10XCP is sized for 12-10 AWG stranded copper wire, and the yellow insulation is the standard color code for that range. Both ends take the same gauge range, so it joins 12 to 12, 10 to 10, or 12 to 10. For 16-14 AWG you need a blue-coded splice instead, and for 22-16 a red one.

The 2RC10XCP vinyl insulation is rated to 105 degrees C, so it suits fixture and equipment compartments where conductor insulation is typically 90 C THHN. Where a luminaire or appliance requires 150 C or 200 C leads, use a nylon or high-temperature splice rather than vinyl.

Use a proper insulated-terminal crimp tool matched to the 12-10 AWG yellow die or nest. Pliers deform the barrel unevenly and you lose both the mechanical hold and the conductivity the copper barrel is there to provide. No tool is supplied with the splice.

A butt splice like the 2RC10XCP makes an inline, low-profile connection, which is what you want inside a raceway-fed fixture canopy, a piece of equipment, or anywhere a bulky twist-on connector will not fit and the splice has to lie flat. Twist-on connectors are quicker for multiple conductors in a box and need no tool. The crimped vinyl splice is also the better choice on stranded conductors subject to vibration.

Country of origin on the 2RC10XCP is the United States, which is what government, education, and healthcare procurement teams usually need documented for domestic-content requirements on electrical material.

Crimp butt splices are intended for stranded copper conductors. The 2RC10XCP has a copper barrel sized for 12-10 AWG, and solid conductors do not compress into the barrel the way stranded does, so a twist-on or a set-screw connector is the better call on solid building wire.

The 2RC10XCP is supplied as a mini-pack, which is the small count-pack intended for service vans and MRO stock rather than bulk box quantities. If you are standardizing an electrical crib across a facility, order by the pack rather than individually.
