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.

  • Approved by the consumer product safety committee (CPSC), UL listed, approved by insurance companies
  • Most cost-effective solution for repairing aluminum wiring systems
  • Three ports allow conductors to remain separate, permitting the lug to run at a lower temperature and provide longer term reliability
  • Secure mechanical connection
  • Contains a layer of corrosion inhibitor that provides resistance from oxidation
  • Made in the USA

Is the minimum gauge for AL really 12? Household wiring is 14 gauge. Does the connector support #14 AL wire?

Rated 4.6 out of 5 by 21 reviewers.
Rated 3.0 out of 5.0 by Wire COnnectors This product is one of only a few listed al/cu connectors. It also does cu/cu, and al/al. I don't know why they have to be so rediculously expensive, but given the cost of an electrician, they are a small percentage of the total project cost. I'm a licensed electrician and have a couple clients with electric heat and aluminum building wiring. When the old connections fail, it's almost always because of poor workmanship, not the old connectors, but these are trying to legislate against incompetence. They reqauire a torque screwdriver for proper application, but have an alternate method of torquing that doesn't reqauire a calibrated screwdriver. Theypre quite bulky and make a single gang box very tight. I use the calibrated screwdriver. KUDOS to Home Depot for having these on line. The product is great, the cost rediculous. January 19, 2016
Rated 4.0 out of 5.0 by Please give real dimensions in specifications The dimensions in the specification are rediculous. It wouldn't fit in a box if it was that big. January 22, 2016
Rated 5.0 out of 5.0 by The only safe DIY option for aluminum wire remediation There are only two products approved by the Consumer Products Safety Commission for safe remediation of aluminum branch wiring, and I chose this product because Alumiconn is one of them. Alumiconn connectors are the only option that homeowners can install themselves. The product is easy to install and a little larger than a wire nut. I have installed many of these throughout my home, and have had no issues with them. You simply strip back the insulation 5/16", insert the wire into the connector and tighten the screw to the recommended torque. I also purchased a torque screwdriver to make sure that I installed them correctly. You will need a minimum of 2 connectors for each outlet, and a minimum of 3 for each switch. If you also need to put these on aluminum ground wires in the box or on 3-way switches, you may need as many as 4 or 5 in a box. Fitting 4 connectors in a box is difficult, but can be done by careful routing and packing of the wires. If there is not enough room, installing a larger remodeling box is not that difficult. One of the other reviews here said to use Ideal In-Sure connectors if you don't have enough room for Alumiconn. Ideal Industries clearly states that In-Sure connectors are not to be used with aluminum wire. Alumiconn connectors are the only safe option. Using In-Sure connectors may increase the chance of a house fire. December 9, 2015
Rated 4.0 out of 5.0 by 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. January 1, 2014
Rated 5.0 out of 5.0 by Easy install Makes transition from aluminum to copper wire easy and safe July 28, 2015
Rated 5.0 out of 5.0 by alumiconn connectors I live in a one bedroom condo of about 900 sqr feet and ended up ordering 3 twenty-five count bags. Glad they were 3 terminal as they were easier to grip than what i imagine a 2 terminal lug would afford but also allowed for connecting 2 common wires and a pigtail at outlets. Gfci outlets require more of course if they have a load. Indeed the set screws are soft and i found that the proper size bit is very important. The slotted bit that comes with the neiko torque screw driver has a narrow footprint and can damage the set screw. A great product if you have aluminum wiring and non compliant switches and outlets.

Rated 5.0 out of 5.0 by Easy to use, work great! Perfect for pig-tailing / splicing copper into aluminum. Compact enough to fit in electrical boxes. July 1, 2014
