How many moves of the hand should it take to shut down the electrical supply?

The recommended practice in electrical safety involves following a specific procedure to ensure that the electrical supply can be safely shut down. The correct answer, which indicates that it should take six moves of the hand to accomplish this task, aligns with the established guidelines that promote safety and minimize the risk of accidental re-energization.

These six moves typically consist of specific actions such as deactivating circuit breakers, switching off control panels, or physically disconnecting equipment. Each movement is designed to systematically isolate the electrical supply, ensuring that all potential sources of energy are addressed. This careful approach is essential because it provides multiple checkpoints to confirm that the power is indeed off, thus enhancing overall safety.

Understanding the rationale behind having a set number of moves helps emphasize the importance of methodical procedures in electrical work. Each step serves a purpose in ensuring that the individual is not exposed to live electrical components during maintenance or troubleshooting. Therefore, adhering to the guideline of six moves supports a culture of safety and reliability in handling electrical systems.
