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.

Q:Do light fixture tails need this product? Most tails are #16 or 18 gage wire. Most tails have a siver
coating on the wire, is that OK?

Answer This Question
A:Â Hey Mark, these specifically are used in Copper to Aluminum connections so if that is part of the application then I would say yes. The wire range we have on these is 18-10 AWG for solid/stranded copper and 12-10 AWG for solid aluminum wire. The silver coating on the wire could be just a tin-coating which helps conductivity and reduces corrosion which won't hinder the connection. Hope this helps!

This product can be very difficult to use. First difficulty is working in small electrical boxes. Second, an expensive torque screw driver must be used to tighten the set screws in the product. Third, if the power isn't turned off, a person could receive a powerful electrical shock which could be fatal. The only reason to use this product is if you have aluminum wiring and it needs to be pigtailed with copper wire.

"The Only Game In Town" to bring aluminum-wired houses up to code, one needs a torque-limiting screwdriver to install these accurately. They take up a lot of space in the box and it was unfortunate that stores did not have the 2-port connectors as well, space-savers when simple CU pigtails will do the trick; available spl. order. Planning each install is important, leaving enough room to close, and later open each cover for instance, and allowing room for the screwdriver (a right-angle screwdriver is also helpful). For branch-circuit convenience outlets, the community consensus seems to favor "close wiring" as shown in the accompanying photo of a 2-ckt receptacle (for dishwasher and disposal; undersink and lots of fun if you are a contortionist !)

A less expensive option than rewiring the house
I started with a small order of these and ended up with the 100 count bag. They worked and are one of the only options for pig tailing aluminum house wire to copper only switches and plugs. I purchased a home in which all switches and plugs had cu or copper only stamped on them. The aluminum house wire was connected to these. (Fire Hazard). After much investigation I found out that you should install copper pig tails because most commonly found switches and plugs are copper only. This product is approved for aluminum (AL) to Copper (CU) connections. The wire connectors have anti corrosion gel in them to prevent the aluminum wire from corroding. The only issue I encountered was that the screw terminals were a little soft, make sure you use the right size screwdriver. Also they recommend using a torque screwdriver. The larger bag had optional instructions if you didn't have a torque driver.

3-port AlumiConn did the job
3-port AlumiConn worked well. Only concern is the hinge portion of the cap. It got very white when flexed to close, like it was about to crack/split. Not sure how weathering will affect it, i.e. become brittle and crack and expose screw terminals.
The Twister AL/CU Wire Connector is the onlyThe Twister AL/CU Wire Connector is the only UL Listed aluminum-to-copper twist-on connector. The connector prevents aluminum oxidation while providing a secure connection. Filled with an anti-oxidant compound, the Twister AL/CU easily twists on with swept-wings making a comfortable connection with improved conductivity and cooler connections.View Full Product Description
