In an operating room, which electrical system is required to supply power for lighting and receptacles used during procedures?
Answer: Isolated power system
NEC 517.160 requires isolated power systems in wet procedure locations including operating rooms to prevent microshock and protect against single-fault conditions.
For wiring in a patient care area, which wiring method is NOT permitted?
Answer: Non-metallic sheathed cable (NM)
NEC 517.13 prohibits non-metallic sheathed cable in patient care areas because it does not provide the metallic path required for low-impedance grounding.
The essential electrical system in a hospital must have the transfer switches for the life safety branch:
Answer: Separate from all other transfer switches
NEC 517.30(B)(3) requires that transfer switches for the life safety branch be separate from transfer switches serving other branches.
What is the minimum number of receptacles required at each patient bed location in a critical care area?
Answer: 8
NEC 517.19(A) requires a minimum of 14 receptacle outlets per patient bed location in critical care areas to support numerous life-support devices.
Where must the equipment grounding conductor in a patient care area be insulated?
Answer: Throughout its entire length from panel to receptacle
NEC 517.13(B) requires the equipment grounding conductor to be insulated throughout its entire length in patient care branch circuit wiring.
In a health care facility, a 'critical care area' differs from a 'general care area' primarily because:
Answer: Patients in critical care are subject to more invasive procedures and have less ability to respond to electric shock
NEC 517.2 distinguishes critical care areas as spaces where patients are connected to electromedical devices or are otherwise more vulnerable to microshock hazards.
Under NEC 517, which of the following is connected to the equipment branch of a hospital Type 1 EES?
Answer: Central suction systems
NEC 517.34 specifies that central suction systems serving medical or surgical functions are connected to the equipment branch of the essential electrical system.
