Warm cowl plates or discolouration of switches or receptacles, flickering lights or the scent of hot plastic insulation could additionally be proof of poor or improperly made connections.
Loose connections increase electrical resistance, which may melt fixtures and insulation. Approved copper-to-aluminum connections plus antioxidant compounds must be used.
