Aluminum has a better rate of expansion than copper wiring, which can lead to free connections, arcing and melting, eventually hearth. Warm cover plates or discolouration of switches or receptacles, flickering lights or the smell of hot plastic insulation may be proof of poor or improperly made connections.
Loose connections enhance electrical resistance, which might melt fixtures and insulation. Approved copper-to-aluminum connections plus antioxidant compounds should be used.
