INTRODUCTION
The NYC Electrician Examination assesses the competency of candidates seeking licensure as electrical
professionals in New York City. This comprehensive assessment evaluates knowledge of electrical theory,
code compliance, safety practices, and practical application skills. The examination structure includes
multiple-choice questions and scenario-based problems that test real-world decision-making abilities.
Candidates must demonstrate proficiency in interpreting the National Electrical Code, NYC Electrical
Code amendments, grounding and bonding principles, overcurrent protection, and professional
judgment. The emphasis is placed on practical application and the ability to make sound professional
decisions in diverse electrical installation and maintenance scenarios.
SECTION ONE – QUESTIONS 1–100
Question 1
What is the primary purpose of the National Electrical Code?
,A. To provide design specifications for electrical engineers
B. To establish minimum requirements for safe electrical installations
C. To recommend best practices for electrical maintenance
D. To certify electrical equipment manufacturers
🟢 Correct answer: B
🔴 Explanation: The NEC serves as the foundational safety standard that establishes minimum
requirements for electrical installations to protect persons and property from electrical hazards. It is
not a design manual or equipment certification program.
Question 2
A qualified person is defined in NFPA 70E as one who:
A. Has completed an apprenticeship program
B. Has received safety training and demonstrated skills in electrical work
C. Has at least five years of field experience
D. Holds a valid electrician license
🟢 Correct answer: B
🔴 Explanation: NFPA 70E defines a qualified person as someone who has received safety training to
identify hazards and has demonstrated the ability to perform work safely. Experience alone does not
qualify someone without documented training and skill demonstration.
Question 3
When performing a load calculation for a dwelling unit, the general lighting load is calculated at:
A. 1 volt-ampere per square foot
B. 2 volt-amperes per square foot
C. 3 volt-amperes per square foot
D. 5 volt-amperes per square foot
🟢 Correct answer: C
🔴 Explanation: NEC Table 220.12 specifies that dwelling units require a general lighting load of 3 volt-
amperes per square foot. This forms the basis for calculating the minimum lighting load for residential
occupancies.
Question 4
,A conductor with THHN insulation has a temperature rating of:
A. 60°C
B. 75°C
C. 90°C
D. 105°C
🟢 Correct answer: C
🔴 Explanation: THHN insulation is rated for 90°C. However, ampacity must often be selected from the
75°C column per NEC 110.14(C) when terminations are rated 75°C, which is common for circuits
exceeding 100 amperes.
Question 5
What is the minimum working space depth required in front of electrical equipment operating at 480
volts to ground with exposed live parts on one side?
A. 3 feet
B. 3.5 feet
C. 4 feet
D. 5 feet
🟢 Correct answer: C
🔴 Explanation: NEC Table 110.26(A)(1) requires a minimum working space of 4 feet for equipment
operating at 480 volts to ground with exposed live parts on one side and no live or grounded parts on
the other side of the working space.
Question 6
A residential customer reports that circuit breakers in their panel frequently trip. Upon inspection, you
find multiple 15-ampere breakers protecting 12 AWG copper conductors. What is the most
appropriate professional response?
A. Replace all breakers with 20-ampere units since the wire can handle it
B. Inform the customer that frequent tripping indicates normal operation
C. Investigate the loads on each circuit to identify overload conditions
D. Install larger breakers and document the modification
🟢 Correct answer: C
🔴 Explanation: Proper professional judgment requires investigating the root cause of breaker tripping
rather than simply increasing breaker size. The 12 AWG conductors could support 20-ampere
protection, but the circuits may be overloaded or have faults requiring diagnosis.
, Question 7
The NYC Electrical Code requires that rigid metal conduit be used in which of the following
applications where the NEC might permit alternatives?
A. Single-family residential branch circuits
B. High-rise building electrical systems
C. Temporary construction power
D. Low-voltage landscape lighting
🟢 Correct answer: B
🔴 Explanation: The NYC Electrical Code contains amendments requiring rigid metal conduit in many
applications, particularly in high-rise buildings, where the NEC would permit other wiring methods.
This reflects NYC's more stringent local requirements.
Question 8
What is the maximum allowable voltage drop for a branch circuit according to NEC recommendations?
A. 1%
B. 2%
C. 3%
D. 5%
🟢 Correct answer: C
🔴 Explanation: NEC 210.19(A) Informational Note No. 4 recommends that branch circuit voltage drop
not exceed 3% at the farthest outlet. Combined feeder and branch circuit voltage drop should not
exceed 5% total.
Question 9
An equipment grounding conductor serves which primary function?
A. Carries normal operating current
B. Provides a low-impedance path for fault current
C. Balances voltage between phases
D. Reduces electromagnetic interference
🟢 Correct answer: B
