This comprehensive study guide is specifically designed for professionals preparing for the New York City
Health + Hospitals (H+H) electrical trade exam. It covers the NYC Electrical Code (NYCEC), NEC
Article 517 (Health Care Facilities), advanced load calculations, and municipal safety standards.
Core Study Domains Included:
NYC Administrative Code: Filing requirements, Master Electrician regulations, and permit types.
Essential Electrical Systems (EES): Life Safety, Critical, and Equipment branches for hospitals.
Calculations: Voltage drop, box fill, motor circuit ampacity (MCA), and transformer sizing.
Special Occupancies: Hazardous locations, wet procedure locations, and anesthetizing areas.
Safety & Compliance: OSHA Lockout/Tagout, grounding electrode systems, and redundant
grounding.
1. According to the NYC Electrical Code, what is the maximum number of service
disconnects permitted for a single building?
A) 2
B) 4
C) 6
D) 8
,Explanation: NYCEC and NEC 230.71 state that the service disconnecting
means for each service shall consist of not more than six switches or sets of circuit
breakers.
2. In New York City, a "Temporary Light and Power" permit is valid for a maximum
of how many days?
A) 30 days
B) 90 days
C) 180 days
D) 365 days

(construction/exhibitions) to 90 days, after which an extension or permanent filing is
required.
3. What is the minimum size for a copper service lateral in New York City?
A) #4 AWG
B) #2 AWG
C) 1/0 AWG
D) 2/0 AWG
Explanation: NYC-specific amendments mandate a minimum of #2 AWG for
service laterals to ensure physical durability and a baseline for future load increases.
4. A 120V circuit has a 15A load using #12 copper wire over 100 feet. What is the
voltage drop? (
ohms/1000ft)
A) 2.44V
B) 5.79V
C) 3.12V
D) 4.55V
Explanation:
,.
5. How many #10 AWG THHN conductors are permitted in a 4" x 1-1/2" square
metal box?
A) 5
B) 7
C) 8
D) 10
Explanation: NEC Table 314.16(A) gives this box a 21.0 cu in capacity. #10 wire
requires 2.5 cu in.
. Max is 8.
6. What is the minimum required rating for the branch-circuit protection of a 5 HP,
230V, 1-phase motor (28A FLC) using an inverse time breaker?
A) 35A
B) 50A
C) 70A
D) 100A
Explanation: Inverse time breakers are sized at 250% of FLC.
.
7. In a patient care space, the "Critical Branch" must be restored within how many
seconds?
A) 5 seconds
B) 10 seconds
C) 30 seconds
D) 60 seconds
, Explanation: NEC 517.31 requires Life Safety and Critical branches to be
restored by the generator within 10 seconds.
8. Which of the following is part of the "Life Safety Branch" in a hospital?
A) Exit sign illumination
B) Operating room task lighting
C) Blood bank refrigeration
D) General ward receptacles
Explanation: Exit signs are for evacuation (Life Safety). OR lighting and blood
banks are Critical Branch.
9. Receptacles in "Patient Bed Locations" require:
A) Metal raceway only
B) Uninsulated ground wire
C) Redundant grounding (Insulated Wire + Metal Raceway)
D) GFCI breaker only
Explanation: NEC 517.13 requires two paths to ground to prevent micro-shocks
to patients.
10. Who is authorized to remove a lockout/tagout safety lock?
A) The Supervisor
B) The Facility Manager
C) The person who installed the lock
D) Any Licensed Master Electrician
Explanation: OSHA 1910.147 mandates that only the authorized employee who
applied the device can remove it.
11. A Class A GFCI must trip between:
A) 2mA and 4mA
B) 4mA and 6mA
C) 10mA and 15mA
D) 20mA and 30mA
Explanation: Personnel protection GFCIs trip at a maximum of 6mA.
12. Max distance between supports for 1/2" EMT?
A) 3 feet
