Is a site-isolating device required to contain overcurrent protection when installed at the distribution point for multiple agricultural buildings?

• A. True
• B. False
• C. Only in certain cases
• D. Only if specified

Answer: (A)

A site-isolating device, such as a disconnect switch or circuit breaker, must include overcurrent protection when installed at the distribution point for multiple agricultural buildings to ensure the safety and reliability of the electrical system. This requirement is based on the necessity to protect the equipment and wiring from overload conditions or short circuits that could arise in a multi-building setup. In scenarios where multiple buildings share a distribution point, overcurrent protection serves to isolate the electrical load specific to each building and prevent potential hazards that could lead to fire or equipment damage. This integration ensures that in the event of an overload in one building, the protection limits the impact to that specific area rather than affecting the entire distribution system. While there may be specific conditions under which simpler configurations might suffice, the best practice and code requirement lean toward including overcurrent protection as a standard safety measure in these installations. Thus, having a site-isolating device that contains overcurrent protection aligns with the safety standards and reduces the risk associated with electrical distribution across multiple agricultural structures.
