It Is Important to Know How to Repair Aluminum Winding Wire


    The aluminum winding wire is better in electrical distribution and transmission. However, typical household wiring devices (GFCI, receptacle outlets, light switches, etc.) are not rated for aluminum wire. As a result, an aluminum wired house is more at risk to reach hazardous fire conditions at the outlet wiring connections rather than homes that are wired with copper wires.

    Unfortunately, electrical aluminum wires rarely show signs of deterioration. However, If you detect any of the following signs:
    Hot to the touch electrical outlet or light switches
    Electrical circuit that does not work
    Flickering lights
    The smell of burning plastic at electrical receptacles
    repair aluminum electrical wire damage

    You potentially have an aluminum wire problem and you should contact a licensed electrician to address it. Do not try to do it yourself. You could get electrocuted or cause an electrical fire.
    The Consumer Product Safety Commission (CPSC) only recommends the following three methods to fix aluminum wire problems permanently
    Completely replace your home with copper wire
    Pigtail the aluminum wire ends with special crimp connectors called COPALUM
    Connect the aluminum wire ends with aluminum to copper AlumiConn wire lug connector
    repair aluminum wire damage

    Rewiring your entire home with copper wire can be quite costly and impractical. As an alternative, the COPALUM and the AlumiConn methods are the most cost effective ways to address your aluminum wires.

    The COPALUM and the AlumiConn methods consist of connecting copper wire to the end of the aluminum wire using a special COPALUM crimp connector or an AlumiConn wire lug connector. This process is often referred to as pigtailing. The repair must include all direct connections or splices involving aluminum wire in the home such as but not limited to electrical outlets, light switches, GFCIs, appliances, light fixtures and junction boxes. As a result, standard copper wiring devices (receptacles and dimmers) can now be safely connected to the home aluminum wires.
    The COPALUM method can only be administrated by a certified COPALUM electrician who has been trained by the special dedicated tool and crimping die manufacturer. Please visit to find a certified COPALUM electrician near your area. The tool will not be available to you unless you have been trained by the manufacturer.

    The AlumiConn method is the most accessible and cost effective solution to addressing Aluminum electrical wiring issues. Unlike the COPALUM method, any certified electrician can repair your Aluminum wires with the AlumiConn wire lug connectors. The process consists of pigtailing using a setscrew type wire lug instead of a COPALUM crimp connector. This process must be applied to all direct aluminum wire connections to copper wiring devices, electrical equipment and light fixture.
