What is the FIRST step in replacing a fuse?

In the process of replacing a fuse, the first and most crucial step is to de-energize the switch box. This step ensures safety by disconnecting the electrical flow, thus preventing any risk of electric shock while handling the fuse. De-energizing the system should always be prioritized to create a safe working environment before any other actions, such as obtaining tools or a new fuse, are taken. By ensuring that the electrical circuit is completely non-energized, you can confidently proceed with the replacement without the danger of current running through the lines. Safety protocols, including de-energizing the circuit, are fundamental practices in electrical maintenance to protect oneself and prevent accidents.
