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

Answer: 
The connector supports #12- #10 solid aluminum and #18- #10 solid copper. Aluminum household wiring is usually 2 awg sizes lower than a copper wire would be for the same circuit amperage. The lower the gauge, the thicker the wire. For copper household wiring you would normally see 14 awg used on 15 amp circuits and 12 awg used on 20 amp circuits. For aluminum you would see 12 awg on a 15 amp circuit and Read More

You can use calipers to measure the thickness of the bare wire if theres no info on the covering. If you do have 14 awg aluminum wiring in your house, it should be replaced. Read Less

Answer: 
These are UL-listed for use only with #12 - #10 solid aluminum. I think you will find that any 15-amp circuits in your home wired with aluminum are #12, not 14AWG, as aluminum does not have quite the conductivity that copper has. The ports on these are rated for #18 - #10 solid or stranded copper. Be sure to torque these connectors properly.

Answer: 
I think 12 is likely the maximum gauge so 14 and smaller gauge wire will work. I am currently using it with 18 gauge stranded wire in a 12-volt application - it completes the connection with no problem.

Answer: 
I just use the wires from 12/2 romex with the yellow covering removed. I use 12 gauge because you can use it on either a 15 or 20 amp circuit but 14 gauge wire can only be used on a 15 amp circuit. A 15 ft roll of 12/2 romex is around $10 and you can make plenty of pigtails.

I just bought a length of 12-2 with ground household wire and cut the lengths myself. Depending on the box type you have (how much room in the box and how many connections you will make) as well as the size of wire currently used in your home, 14-2 with ground may be better.

3-Port Al/Cu Wire Connectors (10-Pack) is rated 4.6 out of 5 by 29.
Rated 5 out of 5 by from The safe alternative Though the National Electrical Code permits Special wire nuts on aluminum wiring the Consumer Product Safety Commision says they should be considered temporary at best. The CPSC recommends Alumicons or Copalum connectors, and the Copalum requires a special crimper that can only be rented by electricians certified to install that product. These Alumicon connectors are easy to use and can fit in most boxes There are instruction for installing with a torque-limiting screwdriver or an ordinary flat blade screwdriver. I replaced most of my home's wiring with copper, but that I couldn't reach, I pigtailed with Alumicons. Now I sleep better.

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

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.
