When is a fault considered cleared in an electrical circuit?

A fault in an electrical circuit is considered cleared when the isolation of the circuit is completed. This means that the circuit has been disconnected from the power supply, which allows for safe maintenance and troubleshooting. Isolation ensures that any remaining energy in the system is safely dissipated and that it is safe for personnel to approach or work on the circuit.

When a circuit is isolated, it guarantees that there are no electrical hazards present, which is crucial for preventing accidents and ensuring safety during repair or inspection. While other factors such as normalizing current flow, identifying the cause of the fault, or replacing equipment are important in the overall maintenance and operation process, they do not signify the immediate safety and operational status of the circuit as effectively as proper isolation does.
