A switchboard is primarily intended for which of the following?

The primary intention of a switchboard is to provide accessibility for maintenance. This ensures that electrical equipment can be easily reached for inspections, repairs, or upgrades, which is critical for maintaining safe and efficient operations. The design and arrangement of switchboards are governed by the need for personnel to work safely around live electrical components, thus prioritizing accessibility.

In contrast, while installation in cabinets, single-axis operation, and control of general lighting may be functions associated with electrical equipment and systems, they do not capture the primary purpose of a switchboard. Cabinets can house various types of equipment, but they don’t specifically define the function of a switchboard. Single-axis operation is more about the mechanical movement of devices rather than the electrical distribution function of a switchboard. Similarly, while switchboards may play a role in controlling general lighting, their main responsibility lies in power distribution and providing a safe environment for maintenance tasks.
