Aluminum to Copper Wire Connectors, Copper to Aluminum Wire Connectors with 2 Port, 10 Pack

These are great connectors for use when you are replacing outlets or switches that no longer allow the use of CU/AL wire. Aluminum house wiring requires copper pigtail to be used on most modern outlets and switches. Theses connectors are great for that but do take up space in the existing electrical boxes. Would suggest using a toque screwdriver and setting the aluminum to 15 in/lb. and the copper to 10 in/lb. Don't forget to use the antioxidant on the aluminum connections.

I'm totally blind. I got these for use in my house being I have that type of wiring and it is ahrd to find switches and the like for it. These have came in handy for people to help me swap out switches and to also put in a few ceiling fans so it is done correctly. Most switches and all ceiling fans are for copper wiring. This away I know things are done correctly and will also meet code when I go to part with the house. These will handle two wires one of each type that you screw down. Then you flip close the lid on them. That is all that is two them. Just had to do that a week or so ago. swapped out a switch for a old fan that was half and half. Power wire was the old wire and the Copper wire went up to the fan. So had to add a pig tail to make it copper so it could be screwed onto the switch being the old switch was for a 30 year model of fan to be able to control it. The new fan wouldn't work with it, so put in a standard Off/On switch.

Buy the real thing Alumiconn made by King Innovation--also available on Amazon.These are no good! When you tighten them, the slot in the screw chips off.

Ideal for light switches or for ground wires inside receptacle boxes.

The product had ox guard in the terminals makes converting aluminum to copper a breeze.Love this product

These are to refill my parts drawer since I used up the last ones putting up 4 light fixtures this last month. They are not nearly as messy as that gray pooky that gets on everything. These also handle connecting different size wire gauges to each other much better than the screw-on nut caps. These are larger than the nut caps, so they may not work with large switches in small/shallow boxes.

Probably best way to join copper and aluminum wire short of rewiring the screw wells allows copper and aluminum to be independently connected without joining the dissimilar metals and corresponding problems and hazards

These are supposed to torque at 10-15 in-lbs. The heads would strip out before that torque was obtained. However, the triple Kingston connectors torqued properly.
