Warm cowl plates or discolouration of switches or receptacles, flickering lights or the odor of scorching plastic insulation may 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 ought to be used.
