How to Safely Work with Aluminum Wiring in Your Home

I want to share my experience and advice for safely working with aluminum wiring in your home. Aluminum wiring was commonly installed in American homes built between 1965 and 1973. While safe if properly installed and maintained, aluminum wiring does require special precautions.

Dangers and Risks of Aluminum Wiring

Aluminum wiring carries higher amounts of electricity than copper wiring of the same size. However, aluminum expands and contracts more than copper. Over time, this can loosen connections and lead to overheating, arching, and potential fires.

The greatest risks come from loose connections. Poor installations, improper maintenance, and even temperature changes can all loosen connections between the aluminum wire and devices like outlets and switches.

Loose connections create heat buildup as electricity passes through. This heat can degrade and corrode the wire, making it expand and contract even more. Ultimately, the loose connection sparks a fire.
