But an electrician can make the connections safe by including a brief section of copper wire to the end of every aluminum wire.

Oxidation has few practical implications aside from the corrosion that can happen at connection websites due to it.
Electricity is transmitted from the utility generating stations to particular person meters using nearly completely aluminum wiring. In the us, utilities have used aluminum wire for over one hundred years. Between the early Nineteen Sixties and the Nineteen Seventies, more than two million properties across the United States had been outfitted with aluminum wiring. By the Nineteen Seventies, it became obvious that there were some critical hazards to aluminum wiring. Rewiring and upgrading is usually required by Insurance Companies. They have data on the hazards of aluminum wiring, and base their decisions on this information.

The resulting oxidization causes the connection point to get even hotter. Over time, the connection can turn out to be free, creating arcing which in turn may end in a fireplace hazard. Reported problems with aluminum wiring have been related to the overheating and failure of aluminum wiring terminations. This is because of the tendency of aluminum wiring to oxidize, and aluminum’s incompatibility with gadgets designed to be used with copper wiring only. Aluminum has a better price of enlargement than copper wiring, which can lead to loose connections, arcing and melting, ultimately fire. Warm cover plates or discolouration of switches or receptacles, flickering lights or the smell of hot plastic insulation may be evidence of poor or improperly made connections.
Loose connections enhance electrical resistance, which may melt fixtures and insulation. Approved copper-to-aluminum connections plus antioxidant compounds must be used.
