PRACTICE EXAM QUESTIONS AND
VERIFIED ANSWERS
1. In a patient care space of a NYC hospital, what is the specific requirement for grounding of
receptacles according to Article 517?
A. A single insulated copper equipment grounding conductor is sufficient.
B. The metal raceway system alone is considered an adequate ground.
C. Non-metallic sheathed cable is permitted if it contains a 10 AWG ground.
D. Redundant grounding using both a metallic raceway and an insulated copper equipment
grounding conductor.
Answer: D
Conceptual Explanation: NEC/NYC Code 517.13 requires redundant grounding in patient
care areas to ensure safety if one grounding path fails.
2. According to the NYC Electrical Code, what is the maximum time allowed for the Life Safety
Branch to be restored after a power failure in a hospital?
A. 60 seconds
B. 10 seconds
,C. 30 seconds
D. 5 seconds
Answer: B
Conceptual Explanation: The Life Safety Branch and Critical Branch must be connected to
the alternate power source within 10 seconds of power loss.
3. Which branch of the Essential Electrical System (EES) in a hospital typically supplies the
power for illumination of means of egress?
A. Critical Branch
B. Equipment Branch
C. General Branch
D. Life Safety Branch
Answer: D
Conceptual Explanation: Illumination of means of egress, exit signs, and fire alarm
systems are powered by the Life Safety Branch.
4. In a Category 1 (Critical Care) space, what is the minimum number of receptacles required
at each patient bed location?
A. 4
B. 8
C. 14
, D. 20
Answer: C
Conceptual Explanation: Per 517.19(B), each patient bed location in a Critical Care space
must be provided with at least 14 receptacles.
5. What is the maximum voltage drop allowed for a branch circuit in a hospital facility to
maintain efficient equipment operation?
A. 5%
B. 3%
C. 10%
D. 1%
Answer: B
Conceptual Explanation: General engineering practice and NEC recommendations suggest
a maximum of 3% voltage drop for branch circuits.
6. An Isolated Power System (IPS) is primarily used in which hospital area to prevent ignition
of flammable anesthetics or electric shock?
A. Operating Rooms
B. Cafeterias
C. Medical Records
D. Patient Waiting Areas
