Which statement is true regarding overcurrent?

Overcurrent refers to a condition where the current flowing through a circuit exceeds its rated capacity. This situation can lead to overheating of wires and components, potentially causing damage to the electrical system and creating fire hazards. When current levels rise above safe limits, the excess heat generated can deteriorate insulation and other materials, leading to failures in electrical systems.

Understanding overcurrent is crucial for anyone working in utility arboriculture, as it emphasizes the importance of ensuring that electrical systems are appropriately protected and capable of handling the electrical load. Proper design and maintenance practices, including the use of circuit breakers and fuses, can mitigate the risks associated with overcurrent situations and ensure safety for workers and the surrounding environment.
