Sta-Kon 2G21 – Frequently Asked Questions
1) What wire size does the Sta-Kon 2G21 butt splice accept?
The 2G21 is sized for 2 AWG through 1 AWG conductors, so it joins two heavy feeder or service-sized wires end to end. Use it only within that range; a conductor outside 2 to 1 AWG will either not seat in the barrel or will crimp loose. Overall length of the splice is 1.72 inches.
2) Is the 2G21 splice insulated, and do I need to cover it after crimping?
It is a non-insulated butt splice, bare copper with no sleeve. The crimped joint has to be insulated afterward, normally with heat shrink tubing or tape rated for the circuit. That is the trade-off versus an insulated splice: no built-in cover, but you can inspect the crimp and choose insulation that matches the application temperature.
3) Can I use the 2G21 butt splice on aluminum conductors?
No. The 2G21 is a copper splice intended for copper conductors. Aluminum feeders need a connector specifically rated AL or AL/CU with the correct compound, so pick a dual-rated compression splice for that job instead.
4) Will this splice hold up inside a hot luminaire or motor connection box?
Temperature rating is 150 degrees C, so the splice body itself is suited to high-heat enclosures such as fixture compartments and motor terminal boxes. The limiting factor becomes whatever insulation you apply over it and the conductor insulation rating, not the splice.
5) Is the Sta-Kon 2G21 UL listed for inspected work?
It is covered under UL file E9809, which is the reference an inspector or spec reviewer will want for a 600 V splice on commercial work.
6) Do I need a special crimp tool for a 2 AWG butt splice like this?
Yes, at 2 to 1 AWG this is a heavy compression barrel, not something a hand-squeeze tool for 22-10 AWG terminals will set. You need a hydraulic or ratcheting compression crimper with the die matched to the splice size. Plan the tool and die into the job before ordering.
7) Is the Sta-Kon 2G21 made in the USA?
Country of origin is listed as United States or Mexico, which matters if you are submitting for a domestic-preference or Buy American job and need documentation on the lot you receive.
