What should always be alongside the main electrical box for safety?

Having a padlock and labels alongside the main electrical box is essential for safety. The padlock serves as a means to prevent unauthorized access to the electrical box, which is crucial for protecting workers and others from electrical hazards. By locking the box, it ensures that only qualified personnel can access it, reducing the risk of accidental electrocutions or equipment tampering.

Labels are equally important as they provide clear identification of the components, potential hazards, and operational guidelines related to the electrical system. Proper labeling informs all personnel of the risks associated with the electrical box and helps in the event of an emergency or maintenance situation, guiding workers in their tasks and enhancing overall workplace safety.

In contrast, extra power cords, wiring diagrams, and backup generators do not address the immediate safety concerns related to unauthorized access and clear communication about the electrical system. While they may have their own importance in specific contexts, they do not serve the critical safety functions that a padlock and labels provide in the context of securing an electrical box.
