A switchboard is a crucial component in electrical systems, serving as the central point for controlling and distributing electrical power. Ensuring safety and preventing hazards associated with electrical equipment is paramount. Access to a switchboard is restricted to qualified persons, who possess the necessary training and expertise to handle electrical systems safely and effectively.

Qualified persons are typically those who have received specialized training in electrical installation, maintenance, and safety protocols. They are familiar with the potential dangers involved with electrical components and understand how to operate the switchboard without risking injury or equipment damage. These individuals can also identify and mitigate hazards, perform necessary troubleshooting, and ensure compliance with relevant electrical codes and regulations.

In contrast, options such as all employees, visitors, or maintenance staff do not encompass the required level of training or expertise, which is crucial for safely interacting with or working near electrical systems. Allowing untrained individuals access to such equipment could lead to accidents, electrical shocks, or even fatalities. Therefore, limiting access to qualified persons ensures a higher level of safety and accountability in managing electrical systems.
