Is it required for interconnected electrical power production sources to be grouped with service disconnecting means?

In Washington State, it is not required for interconnected electrical power production sources to be grouped with service disconnecting means. This means that while having the disconnect means together could provide convenience for operations and maintenance, it is not a code requirement.

Interconnected power sources, such as solar panels or wind turbines, can indeed have their disconnecting means separate from the main service disconnect. This flexibility allows for a variety of system configurations to accommodate site-specific needs and compliance with local codes and regulations.

Grouping power production sources with service disconnecting means could lead to complicated or unwieldy installations in scenarios where the locations of power sources do not allow for efficient grouping. For these reasons, the absence of a requirement for them to be grouped ensures that systems can be configured in a way that is most beneficial to the operational characteristics of the installations.
