After years of service, what happens to the spring tension fingers in the receptacle?

The correct answer indicates that after years of service, the spring tension fingers in a receptacle tend to loosen up, which can lead to overheating. This loosening occurs as a result of repeated insertion and removal of plugs over time, as well as the physical wear and tear that comes with age. Loose connections can increase electrical resistance, which produces additional heat during operation. This overheating can potentially create a hazardous situation, including failure of the receptacle or even electrical fires if not addressed.

Over time, while environmental factors such as moisture and temperature changes can lead to corrosion, the primary failure mode of spring tension fingers is the loss of tension due to wear. This is a critical aspect of maintaining electrical systems, as ensuring a snug fit between plugs and receptacles is essential for safe and efficient operation. Regular inspections and timely replacements of receptacles can help mitigate these risks.
