6. What is this type of energy isolation device called?

Breaker

Disconnect switch

Fuse

Knob switch

A disconnect switch is a type of energy isolation device used to completely shut off the power supply to a circuit or equipment. It is designed to provide a visible and reliable means of disconnecting the power source for maintenance, repairs, or in case of emergencies. Unlike a breaker or fuse that can be reset or replaced, a disconnect switch physically separates the circuit from the power source, ensuring that no electrical current can flow through. This makes it a crucial safety device in electrical systems, allowing workers to safely work on equipment without the risk of electric shock or injury.
