To ensure quick disconnection from protective equipment, what should be installed?

The correct answer focuses on the importance of having a quick disconnect mechanism in electrical systems to enhance safety during emergencies. An emergency shutdown switch is specifically designed for this purpose, allowing operators to swiftly cut power or disconnect equipment in the event of a fault or an unsafe condition.

Installing an emergency shutdown switch provides a direct method for personnel to stop operations immediately, which helps prevent accidents and injuries during critical situations. It is critical in environments where rapid disconnection can mitigate risks and promote safety.

While grounding mechanisms like traveling grounds and grounding rods serve vital functions in electrical safety by providing paths for fault currents and ensuring overall system safety, they do not serve the objective of immediate disconnection from equipment in an emergency. Similarly, an isolation transformer is used to decouple circuits or provide protection against electrical noise or surges, but it does not provide a quick means to disconnect equipment.

Thus, having an emergency shutdown switch is essential for any system requiring immediate action to protect personnel and equipment from hazards.
