What does isolation refer to in electrical systems?

Isolation in electrical systems specifically refers to the process of disconnecting circuits from the electrical supply to ensure safety during maintenance and repair work. This step is crucial because it ensures that anyone working on the electrical system is not exposed to live electrical current, thus minimizing the risk of electric shock or other hazards.

This procedure often involves using isolators or switches designed to completely disconnect power from certain sections of an electrical installation. It provides a safe environment for technicians to perform their tasks without the risk of electrocution or accidental activation of equipment.

The focus on disconnection for maintenance safety distinguishes this concept from other processes in electricity management, such as temporarily turning off electrical devices or using circuit breakers to prevent overload, which serve different purposes. Disconnecting power for maintenance is a critical safety protocol that must be followed in electrical installations to protect both the technicians and the integrity of the electrical system.
