How should all feeder disconnects supplying the same building or structure be arranged?

• A. In separate locations
• B. In a single location
• C. In multiple locations
• D. At random locations

Answer: (B)

Feeder disconnects supplying the same building or structure should be arranged in a single location for several important reasons related to safety and efficiency. Having all disconnects centralized allows for easier identification and operation during maintenance or emergency situations. When there is a need to disconnect power for safety reasons, having all feeder disconnects in one place minimizes the time and effort required to locate them, thereby enhancing safety for personnel. Additionally, grouping disconnects in a single location can streamline the electrical distribution design, ensuring that circuits are more easily managed and monitored. This arrangement can also help reduce the potential for confusion and mistakes that could arise from having disconnects scattered in different areas. The National Electrical Code emphasizes the importance of making electrical systems safe and accessible, which is achieved through this centralized approach. In contrast, having disconnects in separate or multiple locations can lead to difficulties in managing the system and may increase the risk of safety incidents due to the potential for oversight in a complex layout. Overall, a single location for feeder disconnects is both a practical and regulatory approach to ensuring the safety and reliability of electrical systems in buildings.
