Aluminum Wiring

Aluminum wiring was used in homes during the 1960s and 1970s but is no longer commonly used due to safety concerns. It poses a higher risk of overheating and electrical fires compared to copper wiring, primarily due to expansion and contraction issues and a propensity for oxidation and corrosion. Compatibility problems with electrical devices and potential insurance and resale complications further contributed to its decline in usage. Electricians can make aluminum wiring safer by using specialized connectors, such as COPALUM or AlumiConn, ensuring proper connections and torqueing, employing copper pigtailing for improved conductivity, and recommending regular inspections. Homeowners should consult electricians for the best approach based on their situation and the condition of the aluminum wiring.
