Problems with Aluminum Branch Circuit Wire

By Christopher McDowell

Between approximately 1965 and 1973, single-strand aluminum wiring was sometimes substituted for copper branch-circuit wiring in residential electrical systems due to the sudden escalating price of copper. The aluminum wire needed to be a higher gauge than copper.

Aluminum wiring is permitted with the appropriate installation methods and materials. The problem was at connections, such as receptacles, switches, light fixtures, appliance connections, and at the panel. The solution was special connectors, designed to connect the aluminum with copper safely. We still see aluminum wire when conducting inspections. Some buyers panic when they hear that aluminum wire is present. A qualified electrician can be consulted on the best method to make the specific homes wiring safe.
