The statement "The branch circuits for patient bed receptacles can originate from two separate transfer switches on the emergency system" is:

1. True

2. False

3. Partially true

4. Dependent on hospital protocols

The correct answer is: True

The statement is true because healthcare facilities, particularly hospitals, must ensure a continuous and reliable power supply to critical areas such as patient beds. When dealing with emergency systems, the National Fire Protection Association (NFPA) and the American National Standards Institute (ANSI) provide guidelines that often allow for redundancy and reliability in power distribution. This means that branch circuits for critical receptacles, like those used at patient beds, can be connected to two separate transfer switches. This arrangement ensures that if one power source or generator fails, the other can still provide power, thus maintaining essential services for patient care. The use of two transfer switches contributes significantly to patient safety and the operational integrity of medical facilities, ensuring that at least one source of emergency power will be available at all times, even during outages or maintenance. Other options would imply constraints that do not align with the standard requirements for emergency systems in healthcare settings, which prioritize uninterrupted power supply for patient safety.
