This blog post discusses the danger of single strand aluminum branch wiring in homes, which was used in homes during the 1960s and 1970s as a cheaper alternative to copper wiring. Single strand aluminum wiring can become hot and start to oxidize over time, leading to overheating and even fires. The blog suggests remediation methods, including completely replacing the wiring with copper wiring or retrofitting the existing wiring with connectors specifically designed for use with aluminum wiring. It is important for homeowners with homes built during this time period to have their electrical wiring inspected for single strand aluminum wiring and take steps to remediate it to prevent the risk of fire.
