What is the term used for excessive power flow that can cause equipment failure?

The term used for excessive power flow that can cause equipment failure is overload. In electrical systems, overload occurs when the amount of current or power being drawn exceeds the designed capacity of the equipment. This situation can lead to overheating, damage to components, and ultimately equipment failure if not addressed.

Overload is often associated with a sustained condition rather than a transient spike or fault condition. It results from the continuous operation of equipment beyond its rated limits, leading to increased resistance and potential thermal damage. Properly designed circuits will include protective devices, such as fuses or circuit breakers, to prevent overload conditions from resulting in significant damage.

Understanding overload is crucial for ensuring the longevity and reliability of electrical systems. It enables operators to implement appropriate strategies for load management and protection against potential failure due to excessive power flow.
