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

A copper shortage in the ‘60s caused many properties to be electrically wired with aluminum.
Sometimes aluminum rewiring is replaced by tearing out walls. After the rewiring is complete, you must set up new drywall. Replacing aluminum wiring can value greater than $10,000 to switch.

Reported problems with aluminum wiring have been associated 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 for use with copper wiring only. Aluminum has a higher rate of enlargement than copper wiring, which might lead to loose connections, arcing and melting, finally fire. Warm cowl plates or discolouration of switches or receptacles, flickering lights or the smell of scorching plastic insulation could also be evidence 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 should http://collinlfxk558.bearsfanteamshop.com/electrical-services-definition-1 be used.
