How close must multiple outside feeder disconnecting means be grouped from each other?

In Washington State, the National Electrical Code (NEC) requires that multiple outside feeder disconnecting means be grouped together within a maximum distance of 10 feet from each other. This requirement is in place to ensure safety and accessibility for maintenance personnel or in the case of an emergency. By keeping the disconnecting means within this specified distance, it reduces the chance that a worker would have to travel excessively far or struggle to locate the various disconnects when needed, which is crucial for minimizing hazards.

The grouping is intended to provide a unified approach to isolation and disconnection of power sources, ensuring efficient operation and safety protocols in electrical installations. This is particularly relevant for outdoor settings where multiple feeds may power different buildings or areas, enhancing logical organization and ease of access.

The other options suggest distances greater than 10 feet, which do not meet the NEC standards, thus highlighting the importance of adhering to the established codes for safe electrical practices.
