For feeder breakers in a hospital with a 3000A 480V service that serve critical care, what is required?

For feeder breakers in a hospital that serves critical care areas, ground fault protection is essential to ensure the safety and reliability of the electrical system. Ground fault protection helps to detect and interrupt ground faults quickly. This is particularly important in critical care environments where uninterrupted power supply is vital for medical equipment and patient safety. Ground faults can create hazardous conditions, and protective measures need to be in place to minimize risks.

In a medical facility, particularly in critical care areas, the risk posed by electrical faults can have serious implications. Ground fault protection not only safeguards the equipment and the patients receiving care but also aligns with industry regulations and standards, which often mandate such protections in locations where the risk of patient contact with electrical systems is increased.

While the other options mentioned, such as surge protection devices, arc flash analysis, and overload relays, do play important roles in electrical safety and reliability, they do not specifically address the immediate hazards posed by ground faults in the same way that ground fault protection does. Surge protection devices protect against transient voltages, arc flash analysis assesses risks associated with arc flash incidents, and overload relays prevent overheating due to excessive current. However, for critical care scenarios, the priority is on minimizing the risk of ground faults to ensure patient safety.
