Regardless of the comprehensiveness or cost of an electrical system, its components begin to degrade as soon as they are installed, and failures can consequently occur. If the deterioration is not addressed, it can lead to electrical failures and malfunctions. Additionally, changes in load or circuit modifications may be made without proper overall design coordination, resulting in the improper selection of equipment, misconfigured protective devices, or incorrect installation of trip units in the circuits.
