NYC ELECTRICIAN (NYC HEALTH +
HOSPITALS – NYC H+H) EXAM 2026/27
QUESTIONS AND VERIFIED ANSWERS
1. According to NEC Article 517, which branch of the Essential Electrical System (EES) is
specifically intended to provide power to exit signs and alarm systems?
A. Critical Branch
B. Life Safety Branch
C. Equipment Branch
D. Normal Branch
Answer: B
Conceptual Explanation: NEC 517.33(A) specifies that the Life Safety Branch shall supply
power to illumination of means of egress, exit signs, and alarm systems.
2. In a patient care space, what is the maximum permitted potential difference between any
two exposed conductive surfaces as per NEC 517.14?
A. 10 mV
B. 500 mV
C. 20 mV
D. 100 mV
,Answer: D
Conceptual Explanation: NEC 517.14 requires that in patient care spaces, the potential
difference between conductive surfaces shall not exceed 100 mV in normal operation.
3. What is the minimum number of receptacles required at each patient bed location in a
‘Category 1’ (Critical Care) space?
A. 8
B. 10
C. 6
D. 14
Answer: D
Conceptual Explanation: NEC 517.19(B) requires at least 14 receptacles at each patient
bed location in critical care areas.
4. Which of the following wiring methods is NOT generally permitted for branch circuits
serving patient care spaces according to NEC 517.13?
A. AC cable with an insulated equipment grounding conductor
B. EMT (Electrical Metallic Tubing)
C. Type NM (Romex) cable
D. Rigid Metal Conduit (RMC)
Answer: C
, Conceptual Explanation: NEC 517.13 requires an insulated copper equipment grounding
conductor and a metal raceway or cable armor; NM cable does not meet the redundant
grounding requirement for hospitals.
5. A ‘Wet Procedure Location’ in a hospital requires which of the following for protection
against electric shock?
A. Non-metallic floor mats only
B. Standard AFCI protection
C. Double insulation on all tools
D. Isolated Power System or GFCI protection
Answer: D
Conceptual Explanation: NEC 517.20 requires that wet procedure locations be protected
by either an isolated power system or ground-fault circuit interrupters.
6. What is the maximum delay allowed for the restoration of power to the Life Safety Branch
after a total loss of normal power?
A. 60 seconds
B. 10 seconds
C. 15 seconds
D. 30 seconds
Answer: B
