The NYC Health Hospitals Electrician Exam assesses the knowledge, skills, and abilities required for
competent performance as an Electrician within NYC Health + Hospitals facilities. This multiple-choice
examination includes scenario-based questions that emphasize real-world application, critical thinking, and
professional decision-making in healthcare electrical systems. Candidates will be evaluated on their ability to
install, repair, and maintain high and low tension electrical systems for light, heat, power, fire alarm, and
communications; interpret electrical drawings and blueprints; apply safety practices; understand the NYC
Electrical Code; supervise personnel; and maintain ethical professional standards. The exam prioritizes
practical competency over theoretical knowledge alone, ensuring electricians can safely and effectively
manage electrical systems in complex hospital environments where patient safety and critical care operations
depend on reliable electrical infrastructure.
,Section One: Questions 1–100
Question 1
An electrician in a hospital operating room notices that the electrical line isolation panel is showing an alarm
indicator. What is the FIRST action the electrician should take?
A. Immediately replace the entire isolation panel
B. Notify the engineering supervisor and document the alarm
C. Continue working and check the panel at the end of the shift
D. Ignore the alarm if no visible electrical problems exist
🟢 Correct answer: B
🔴 RATIONALE: In healthcare facilities, operating room electrical safety is critical for patient care. An alarm
indicator on a line isolation panel indicates a potential fault that could compromise patient safety. The first
action must be to notify the supervisor and document the issue per administrative protocols, ensuring proper
tracking and timely repair by qualified personnel.
Question 2
According to the NYC Electrical Code, what is the minimum required clearance above ground for outdoor
overhead electrical conductors rated 0-600 volts in a residential area?
,A. 8 feet
B. 10 feet
C. 12 feet
D. 15 feet
🟢 Correct answer: C
🔴 RATIONALE: The NYC Electrical Code (based on NEC 2020 with NYC amendments) requires minimum 12
feet clearance for overhead conductors 0-600 volts in residential areas to ensure public safety and prevent
accidental contact.
Question 3
When installing conduit in a hospital ceiling above an operating room, which type of conduit is MOST
appropriate for maximizing fire safety?
A. Flexible metal conduit (FMC)
B. rigid metal conduit (RMC)
C. Electrical metallic tubing (EMT)
D. Non-metallic flexible conduit
🟢 Correct answer: B
🔴 RATIONALE: Rigid Metal Conduit (RMC) provides the highest fire resistance and physical protection,
making it most appropriate for critical healthcare areas like operating rooms where fire safety and system
reliability are paramount.
, Question 4
An electrician is calculating the voltage drop for a 200-foot, 3-phase, 480V circuit carrying 100A using 2 AWG
copper conductors. If the calculated voltage drop is 8V, what is the percentage voltage drop?
A. 1.25%
B. 1.67%
C. 2.08%
D. 2.50%
🟢 Correct answer: B
🔴 RATIONALE: Percentage voltage drop = (Voltage Drop ÷ System Voltage) × 100 = (8V ÷ 480V) × 100 =
1.67%. This calculation is essential for ensuring proper equipment operation.
Question 5
Which of the following BEST describes the primary purpose of a ground fault circuit interrupter (GFCI) in
hospital bathrooms?
A. To increase voltage stability
B. To protect against electrical shock by detecting ground faults
C. To reduce energy consumption
D. To prevent overcurrent conditions
🟢 Correct answer: B
