The maximum number of separated service disconnects that can be grouped together is six. This requirement is specified in the National Electrical Code (NEC), which aims to ensure safety and proper functioning of electrical systems. Grouping service disconnects allows for easier access and operation by a single individual while maintaining a manageable number of disconnects to prevent confusion during operation or maintenance.

When multiple service disconnects are installed, grouping them helps ensure that all associated loads can be de-energized effectively when necessary. This grouping is crucial for emergency situations where quick access to power shutdown is needed. Limiting the number to six also helps to ensure clarity in electrical service management, allowing for easier identification of circuits and avoiding overload situations that could arise from having too many disconnects within a single grouping.

While the other options suggest higher maximums, they do not comply with the NEC standards which ultimately dictate this limit for safety and efficiency in residential electrical systems.
