The emergency shutdown procedure for the EPP III requires removing the Key from which component?

Explanation:
In an emergency, you want to cut power to the entire system as quickly as possible. The Master Switch is the main power-disconnecting device for the EPP III; removing the key from it isolates the entire electrical system, preventing re-energization and stopping all subsystems at once. If you were to remove the key from other components, you’d typically only affect that specific part of the system—power could still be flowing through other paths, or the system could be re-energized through the main bus. So the Master Switch is the correct point to pull the key for a true emergency shutdown.
