Product Details

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. AlumiConn is a lug style connector with two 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
  • 2 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
  • Max Voltage 300V
  • Aluminum wire range: #12 - #10 solid AWG
  • Copper wire range: #18 - #10 solid and stranded AWG
  • UL486C Listed to meet US and Canadian standards
  • Temperature rating of insulating material: 105 degrees Celsius
  • Suitable for aluminum to aluminum, aluminum to copper and copper to copper wire splices

Q:Are these rated/approved [CPSC] for GFCI connections? eg. Kitchens & bathrooms. ie. Code Compliant?
by|Oct 1, 2022
1 Answer
Answer This Question

A:  Hi, to our knowledge there is no special rating needed for a connector to work with GFCI outlets though it should be noted that our product is CPSC approved. The AlumiConn should work just fine for your application. Hope this helps!

    Answer This Question

    A:  That silver wire you see on the light fixture is not aluminum wiring. It is tinned copper wire. You should call an electrician to do the work correctly.

    A:  What you are seeing and mistakenly calling aluminum wire is not aluminum at all, but tinned stranded copper wiring. Just use the appropriately sized wire nut.

    A:  That isn't aluminum. It is just copper wire that has been tinned (it is pre prepared for soldering) You can use a wire nut with that. You do not need any special connectors.

    Q:iOS there a connector for #4 aluminum to #4 copper?

    A:  if your asking "4 guage" I do NOT think it will fit...……..NOT

      A:  No, your only option there is copalum crimping from a certified electrician ($$$$$). However, I will say you may not need to worry about that thickness of wire if fear of fire is your concern. If the aluminum is stranded #4 it's generally thought of as safe for use in home. In fact many new homes are still build with low gauge stranded aluminum for dryer and stove hookups. It's the 10-12 gauge solid wires that are super dangerous in homes.

        A:  If you're working with #4 wire, it's probably in a junction box. There should be plenty of aluminum rated buses

        by|Jan 13, 2021

          A:  No not from AlumiCon, only 10-12 solid AL & 10-18 solid and stranded CU

            A:  This connector will accept a maximum conductor size of 10 AWG.

              A:  Sure there is a connector, but not an AlumiConn connector. The quickest and easiest connector would be a Polaris connector which is completely pre-insulated. ILSCO makes a similar and slightly less expensive version of the Polaris connector. The more old school and less expensive connector would be a tin plated split bolt connector with a separator. The split bolt would require insulating with rubber tape and electrical tape to make a finished splice.

                Q:Are these compliant with the NEC copper to aluminum connections code?
                by|Jul 9, 2018
                5 Answers
                Answer This Question

                A:  The NEC doesn’t specify anything about dealing with existing aluminum wiring, only new installations which wouldn’t cover aluminum. However the UL and the US Consumer Product Safety Commission list the AlumiConn connectors as one of three methods for permanent repair, when installed according to their approved method.

                        A:  Although these connectors are compliant with the NEC, the NEC doesn't address aluminum to copper branch circuit wiring connectors. This is the only connector manufactured that is approved by the US Consumer Product Safety Commission. This connector has also been tested and listed by UL.

                        Anything that keeps my aluminum-wired home safe from fire is prudent. These are easy to use, and apparently provide better protection that the previous generation of Al/Cu wire nuts. I purchased a torque screwdriver online to make sure the set screws are seated properly. They take up a little more space in the outlet/fixture/junction box. Although a little pricey, it's the price you have to pay if you have a home with aluminum wiring. Would like to see the two port carried at my local HD, but I can only get the three port there. The photo of the fried outlet is what can happen if you do not provide Al/Cu connectors.

                        2-port AlumiConn worked well for job.
                        2-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.

                        Just what I needed
                        I had to go from aluminum to copper wire. These fit the bill. The wires don't touch each other, so there is no reaction between the two. So far they have worked well.
