By the Nineteen Seventies, it became obvious that there were some critical hazards to aluminum wiring. Rewiring and upgrading is often required by Insurance Companies. They have data on the hazards of aluminum wiring, and base their selections on this knowledge.
A shortage of copper brought on prices to skyrocket right when our nation’s building growth began. Copper costs remained excessive until the mid-1970s, so builders outfitted more than two million homes in the United States with cheaper aluminum wiring.
