The core question pertains to the establishment of regulations prohibiting the use of aluminum as an electrical conductor in residential buildings. Understanding this requires exploring when specific jurisdictions instituted restrictions on its installation due to safety concerns.
The impetus for these limitations arose from documented instances of failures in aluminum wiring systems, primarily related to connection points. These failures, often caused by the properties of aluminum such as expansion and contraction with temperature changes and its propensity to oxidize, led to overheating, fire hazards, and compromised electrical functionality. Consequently, certain locations implemented measures to safeguard residents from the risks associated with this type of electrical system. Regulations vary by location and time.
