Between the early Nineteen Sixties and the 1970s, greater than two million houses throughout the United States had been outfitted with aluminum wiring. By the Seventies, it turned apparent that there have been some severe hazards to aluminum wiring. Rewiring and upgrading is normally required by Insurance Companies.

Warm cover plates or discolouration of switches or receptacles, flickering lights or the odor of scorching plastic insulation may be proof of poor or improperly made connections.
Loose connections improve electrical resistance, which may melt fixtures and insulation. Approved copper-to-aluminum connections plus antioxidant compounds ought to be used.
