What should be done if a major electrical fault occurs?

Isolating power to the affected circuit is essential in the event of a major electrical fault. This action prevents further damage to equipment and reduces the risk of electrical hazards, such as fires or electric shocks, which can occur if the fault continues while power is still applied. By cutting off the power, personnel can safely assess the damage to the circuit and equipment without exposing themselves to danger.

This approach ensures that investigation and repairs can be conducted in a controlled and safe manner, enabling the repair team to identify the fault precisely and determine the necessary steps for resolution. Following this protocol is crucial for maintaining safety standards and protecting both personnel and equipment during electrical maintenance or repairs.
