NYC Health Hospitals Electrician Exam Actual Test
Questions and Correct Answers With Rationales LATEST
THIS YEAR
NYC Health + Hospitals (H+H) Electrician Exam
Exam Coverage Summary
The NYC Electrician (NYC Health + Hospitals) exam tests knowledge of the New York City Electrical Code
(NYCEC) , the National Electrical Code (NEC) with NYC amendments, and healthcare facility electrical
requirements . The exam covers electrical theory, code requirements, healthcare facility systems
(including operating rooms, patient care areas, and psychiatric units), safety protocols, and installation
practices.
Key content areas include:
• Electrical Theory & Fundamentals: Ohm's Law, AC/DC theory, power calculations, units of
measurement
• NEC & NYC Electrical Code: Ampacity tables, conductor sizing, overcurrent protection,
grounding and bonding
• Healthcare Facility Systems: NEC Article 517 (healthcare facilities), isolated power systems (IPS),
line isolation monitors (LIMs), patient care area receptacle requirements, hospital-grade
receptacles (orange with green dot/triangle)
• Emergency Systems: NFPA 110 generator testing, automatic transfer switches (ATS), life safety
and critical branches
• Safety: Lockout/tagout (LOTO), arc flash, confined space entry, GFCI/AFCI requirements
• NYC-specific Amendments: NYC DOB requirements, high-rise provisions, NYCEC amendments to
NEC
Question 1
What is the unit of measurement for electrical current?
A) Volts
B) Ohms
, Page 2 of 136
C) Amperes
D) Watts
Correct Answer: C
Summary Rationale: Amperes (amps) measure electrical current, the rate of electron flow. Volts measure
electrical potential, ohms measure resistance, and watts measure power .
Question 2
What is the unit of measurement for electrical resistance?
A) Volts
B) Ohms
C) Amperes
D) Watts
Correct Answer: B
Summary Rationale: Ohms (Ω) measure electrical resistance, the opposition to current flow in a circuit .

Question 3
What is Ohm's Law?
A) V = I × R
B) V = I + R
C) V = I / R
D) V = R / I
Correct Answer: A
Summary Rationale: Ohm's Law states that voltage (V) equals current (I) multiplied by resistance (R) .
Question 4
What is the unit of measurement for electrical power?
A) Volts
B) Ohms
C) Amperes
D) Watts
, Page 4 of 136
Correct Answer: D
Summary Rationale: Watts measure electrical power, representing the rate at which electrical energy is
consumed or produced .
Question 5
What is the difference between alternating current (AC) and direct current (DC)?
A) AC periodically reverses direction; DC flows in one direction
B) DC periodically reverses direction; AC flows in one direction
C) Both flow in one direction
D) Both periodically reverse direction
Correct Answer: A
Summary Rationale: Alternating current (AC) periodically reverses direction, while direct current (DC)
flows consistently in one direction. AC is used for building power distribution .
