Warm cowl plates or discolouration of switches or receptacles, flickering lights or the smell of hot plastic insulation could also be proof of poor or improperly made connections.
Loose connections improve electrical resistance, which can melt fixtures and insulation. Approved copper-to-aluminum connections plus antioxidant compounds should be used.
