NYC ELECTRICIAN (NYC HEALTH +
HOSPITALS) FINAL EXAM 2026/2027
QUESTIONS AND VERIFIED ANSWERS
1. In a patient care space, which requirement must be met for the grounding of receptacles
and fixed electrical equipment according to NEC 517.13?
A. A single insulated copper equipment grounding conductor is sufficient.
B. Redundant grounding using both a metallic raceway/cable armor and an insulated
copper equipment grounding conductor.
C. The metal raceway system itself is the only permitted ground path.
D. Grounding is only required for equipment operating above 150 volts to ground.
Answer: B
Conceptual Explanation: NEC 517.13 requires two independent grounding paths for
patient care areas: the metal raceway/armor (effective ground-fault current path) and an
insulated copper equipment grounding conductor.
2. Which of the following branches is NOT part of the Essential Electrical System (EES) in a
Type 1 health care facility?
A. Life Safety Branch
B. Equipment Branch
,C. Critical Branch
D. General Lighting Branch
Answer: D
Conceptual Explanation: The EES for Type 1 facilities consists of the Life Safety Branch,
the Critical Branch, and the Equipment Branch. General lighting is usually on the normal
power system unless specific to egress or critical areas.
3. Per NYC Electrical Code, what is the maximum time allowed for the Life Safety Branch to be
restored after a normal power failure?
A. 60 seconds
B. 30 seconds
C. 5 seconds
D. 10 seconds
Answer: D
Conceptual Explanation: NEC 517.31 and NFPA 110 require the Life Safety and Critical
branches to be fully operational within 10 seconds of power loss.
4. A ‘Wet Procedure Location’ in a hospital requires which specific protection for personnel
safety?
A. Standard 20-amp circuit breakers
B. Double insulated equipment only
, C. Twist-lock receptacles only
D. Isolated Power Systems (IPS) or GFCI protection
Answer: D
Conceptual Explanation: In wet procedure locations, protection against electric shock is
required via Isolated Power Systems or GFCI, provided the interruption of power doesn’t
endanger the patient.
5. What is the minimum number of receptacles required for each ‘Patient Bed Location’ in a
Critical Care Area (Category 1)?
A. 8
B. 10
C. 14
D. 6
Answer: C
Conceptual Explanation: NEC 517.19(B) requires each patient bed location in a critical
care area to be provided with a minimum of 14 receptacles.
6. When installing an Isolated Power System (IPS), the Line Isolation Monitor (LIM) must be
set to alarm when the total hazard current reaches:
A. 2 mA
B. 10 mA
