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.

Rated 4.6 out of 5 by 25 reviewers.
Rated 5.0 out of 5.0 by 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. August 17, 2016
Rated 4.0 out of 5.0 by 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 September 30, 2016
Rated 5.0 out of 5.0 by very good the safest way to convert from aluminum to copper wire August 26, 2016
Rated 4.0 out of 5.0 by Useful and practical wire connector I prefer using this product to connect wires rather than with wire nuts and tape. Wires are held securely by the screw terminals and very unlikely to come loose, unlike what can happen with wire nuts. This product is especially useful because of the often increased difficulty for me when connecting 3 wires with wire nuts. However they seem quite expensive at over $3 each. May 25, 2016
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 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 GOOD PRODUCT IS PERFECT FOR THE JOB, AS STATED. A SAFE METHOD OF ATTACHING ALUMINUM WIRE TO COPPER WIRE. December 25, 2012
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
