Define the term "overcurrent."

The term "overcurrent" specifically refers to a situation where the amount of electrical current flowing exceeds the rated capacity of a circuit or the maximum current that the wiring or devices can safely handle. This condition can occur due to various reasons, such as a short circuit, an overload of devices, or a fault in the system. Overcurrent can lead to overheating, damage to electrical components, and potentially hazardous conditions, which is why protective devices like circuit breakers and fuses are used to interrupt the flow of electricity when an overcurrent condition arises.

Understanding this definition is crucial as it emphasizes the importance of adhering to established current ratings to maintain safety and operational integrity within marine electrical systems. Keeping track of the rated capacity prevents accidents and ensures that electrical systems function efficiently without risk of failure due to excessive current.
