Overcurrent refers to a situation in an electrical circuit where the current exceeds the rated capacity of the circuit components. This can occur due to various reasons, such as a short circuit, overload, or equipment failure. When the current surpasses safe levels, it can lead to overheating, damage to electrical devices, or even fire hazards. To protect against overcurrent, devices like circuit breakers and fuses are used. These safety devices automatically interrupt the flow of electricity when excessive current is detected, preventing potential damage. Properly sizing and maintaining electrical systems is essential to minimize the risk of overcurrent situations.
