What is a key requirement for the location of disconnecting means for outside feeders?

The requirement that disconnecting means for outside feeders must be accessible is vital for safety and operational efficiency. Accessibility ensures that in the event of a power outage, maintenance needs, or emergency situations, personnel can quickly and safely reach the disconnecting means to cut off power. This is particularly important in outdoor installations where hazards may arise, and quick response times can mitigate risks.

Making the disconnecting means accessible also means that it complies with NEC guidelines designed to protect both workers and the facilities involved. If disconnecting means were difficult to reach, it could pose serious dangers during emergencies or servicing.

While other options touch on significant considerations, they do not align with the core NEC principle regarding accessibility, which is fundamental to ensuring safety during operation and maintenance of electrical systems.
