What is a potential consequence of mismatched receptacle and cap configurations?

When receptacle and cap configurations are mismatched, one of the most significant concerns is overheating connections. This occurs because improper matching can disrupt the electrical flow, leading to poor contact and increased resistance at the connection points. As a result, the electrical current may generate excess heat, which can damage not only the connection itself but also surrounding components and wiring.

Overheating can lead to insulation breakdown, create potential fire hazards, and ultimately compromise the safety and performance of electrical equipment. Ensuring that receptacle and cap configurations are compatible helps maintain optimal electrical flow and reduces the risk of overheating, supporting safer and more efficient operation of the equipment.

The other options, while they can be serious issues, are not the most direct consequences of a mismatch in this context. Increased voltage typically relates to source supply differences rather than configuration issues, equipment malfunction could be an indirect effect of overheating, and reduced equipment lifespan often results from cumulative damages caused by heat and malfunction over time. However, overheating due to mismatched configurations is a direct, immediate concern that can lead to more severe consequences.
