Did you know that in the 1960's to mid-70's old aluminum wire was used in North America for wiring entire houses? Aluminum wire was widely used as an alternative conductor during a period of high copper prices and many old installations are downright dangerous!
New Aluminum Wiring
Aluminum building wiring is a type of electrical wiring for residential construction or houses that uses aluminum electrical conductors. Since aluminum provides a better conductivity to weight ratio than copper it is commonly used today for wiring power grids, including overhead power transmission lines and local power distribution lines, as well as for power wiring of some airplanes.
Utility companies have used aluminum wire for electrical transmission in power grids since around the late 1800s to the early 1900s. It has cost and weight advantages over copper wires. Aluminum wire in power transmission and distribution applications is still the preferred material today.
OLD Aluminum wiring
Unfortunately, electrical devices (outlets, switches, lighting, fans, etc.) in the 1960's & 70's were not designed with the properties of the aluminum wire in mind. As a result, there were some issues related to the properties of the wire itself, making the installations with aluminum wire much more susceptible to problems.
Revised manufacturing standards for both the wire and devices were developed to reduce problems. Still, existing homes with this older aluminum wiring used in branch circuits present a potential fire hazard.
