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.

  • 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

Customer Questions & Answers

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

Asked by: LittleDrummerBoy
Little known fact, 12 gauge aluminum is equivalent to 14 gauge copper. So no this connector does not support 14 gauge al wire but you also don't have that in your walls guaranteed. In fact 14 gauge aluminum is too small to even be rated to carry any load.

3-Port Al/Cu Wire Connectors (10-Pack) is rated 4.6 out of 5 by 30.

As owner of a home built in 1967 with aluminum wiring, I had few choices when repairing a bad circuit. These connectors were the best solution for connecting the newly run copper cable to the existing aluminum cables going to the lights and the fan in a bathroom. I was surprised at the torque requirements (10 inch pounds for #12 solid aluminum and 15 inch pounds for #10 aluminum and all copper). Fortunately, I had a suitable torque wrench. The connectors do take up quite a bit of room in the junction box. Overall, I was pleased with the way the connectors worked. I gave them a 4-star rating only because I feel they are overpriced based on the materials and construction. However, Home Depot had the best price that I could find.

Rated 4 out of 5 by from Whatta ya gonna do? They work as advertised but are so big I had to use a large remodel box. Outrageously expensive, but so is an electrician or a fire. I'll use the purple al/cu wire nuts if I'm just pigtailing a single aluminum wire to a copper wire. Aluminum wire. What a great way to save money. Kinda like plastic hose for plumbing. Lol

Rated 4 out of 5 by from CPSU-approved underscores product features Used in the past, expensive but good product for remediation of Al wiring issue. HD price was slightly better on 3-ports than other sources I researched & slightly more on the 2-ports I needed. Ordered both from HD for convenience and to save double shipping

REQUIRES A TORQUE SCREW DRIVER TO INSTALL. If you don't have one there are some cheap options available. there's at home depot, I don't have experience with it but it does the correct range of torques for this product. You need a screwdriver that does 10-15 inch pounds. There are instructions on how to do it without a torque screwdriver, but then the connector isn't certified safe, and why would you buy these expensive wire connectors then install them in a way that they arn't safe. From my experience it would be extremely easy to over-torque the aluminum connectors if you don't use a torque screwdriver. the screws actually dent the solid AL when they are torqued properly but you could easily dent them too much without the proper torque since aluminum is so soft. Electrical boxes can get snug with these in them, especially gfci outlets requiring 4 of the. if you want to safe yourself some hassle with the few boxes that have gfci outlets or a number of switches I'd recommend getting some of these: Lastly the prices of these jump around a lot, so if you see a bag of them that's cheaper than the others you might want to buy a bunch at that price. also good to know there are 25 packs available at (usually) a cheaper price per connector:

Rated 5 out of 5 by from 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.
