Product Overview

King Innovation's AlumiConn Aluminum to Copper Lug is approved by the Consumer Product Safety Commission (CPSC), UL, and numerous insurance companies as a safe method for aluminum wiring repair. Manufactured in Missouri, AlumiConn is a lug style connector with three separate ports to eliminate intermixing of conductors. It coats aluminum wires with a thin layer of silicone sealant to provide resistance from oxidation, and uses set screws to break up surface oxides and provide a secure mechanical connection. Avoid a complete re-wire by using AlumiConn, the most cost-effective aluminum wiring repair solution available.

Customer Questions & Answers


I want to order 200 pieces. AlumiConn online, I receive any discount on it ?
Asked by: Irena
I did not find any discounts, Irena, but did figure out that it was $14 cheaper to order four bags of 25 than one bag of 100. Curious, but that the way it penciled out.

Rated 5 out of 5 by from Latest In aluminum wire repair I have a home with Aluminum wiring. The pigtailing to copper has failed in some parts from years ago, this product helped repair the connections. You need to use the torque driver to get consistent results. I Recommend professional installation, Advanced DYI'ers can do it with the torque drivers and some practice. Al is soft and creep can still make connection loose you need to check twice and make sure wire is all the way in the connector before you torque it down.

Rated 4 out of 5 by from A great safety solution for the DIY'er A great product with solid credentials to back it up as the safety product for those of us still dealing with aluminum house wiring and doing our own work. Have used it on some smaller projects and am now ready to tackle all of the aluminum/copper connections in the house. Have not had a single failure yet with any of the components. Easy to install and they don’t use much more space in the boxes than wire nuts. Heads up that if you plan to use the torque method for tightening the screws (recommended) you will need a #5 slot bit and they are almost impossible to find. I ended up using my bench grinder the make one. A square or torx recess screw would be much better.

Rated 5 out of 5 by from Great Product, Best Price This is the only thing I can find as a DIY that meets my local electrical code for copper-clad aluminum wiring junctions. The purple wire nuts with anti-oxidant in them are known for melting down and causing fires because they're joining 2 dissimilar metals (copper and aluminum). Some say the aluminum is coated with the copper and isn't a concern. This wire connector eliminates that argument by allowing the different terminals for each wire/type of metal. The one con is that they are bulky. You can't put as much into boxes with these connectors as you can regular copper wiring.

Rated 5 out of 5 by from Works as advertised; easy to use Bought these to re-terminate some old copper to aluminum connections and to update bathroom outlets to GFCI without rewiring the aluminum circuits. Worked great using a pair of channel locks to hold while torquing. No problems at all as size volume is almost the same as wire nuts.

Rated 5 out of 5 by from Excellent for aluminum to copper Pros: Significantly cheaper than other options Easy to install Well made Similar size to purple wire nuts Cons: Cost of torque screwdriver (but worth it!) When we bought our house, we were told that it had been pigtailed for Al-Cu. I quickly discovered that only about 50% of the house had been done. (And the previous owners had been ripped off by the electrician. I have the documentation to prove it.) I started doing research because I hate wire nuts, and the Cop-Alum solution is very, very expensive. I found these on the site for the Consumer Product Safety Commission. They no longer recommend wire nuts. They recommend these or the very expensive Cop-Alum. The instructions contain steps for using a torque screwdriver, or a regular screwdriver. I decided to go for the torque specs. I am going to do my entire house, so it was worth the $200. Just make sure you get one with a calibration certificate.

Rated 4 out of 5 by from Does the job Been using the Ideal AL rated wirenut.....but....apparently it's frowned upon by decent society:^) So...this is the "approved" connector. I only gave it 4 stars because it takes up a bit to much room in the outlet box (not that King has any other options, or real control over that :)
