Receptacles have metal contact points for hot, neutral, and ground connections that, over time, wear out and lose their gripping power to hold cords tightly. This creates dangerous exposed contact points on the plug and little or no contact with the receptacle blades, which produces heat in the receptacle and the cord. The heat will cause damage to the wiring and likely lead to a circuit breaker tripping or a fuse blowing. As a safety measure, replace all worn out, cracked, or damaged receptacles, all non-polarized receptacles, or any that feel warm to the touch.
How many times have you flipped your light switches off and on over the years? Chances are the switch has been flipped thousands of times. Over time the springs and contact points inside the switch wear out. When the spring lacks enough tension to ensure a tight connection, resistance and heat will increase – causing a potentially hazardous situation. Any switch that feels warm or “sizzles” should be replaced immediately.
Old, outdated, painted-over receptacles and switches just look bad. Give your home a “face-lift” by replacing all those worn out receptacles and switches. Your home will look 20 years younger!
