Introduction
The NYC DCAS Electrician Exam is a rigorous assessment designed to ensure that
candidates possess the specialized knowledge required to perform electrical work safely
and effectively within the unique regulatory environment of New York City. This
,examination evaluates a candidate's proficiency in the National Electrical Code as well as
the specific administrative and technical amendments unique to local statutes. The
assessment utilizes a blend of theoretical multiple-choice questions and complex
scenario-based problems to simulate real-world challenges encountered by electricians.
By focusing on critical decision-making, regulatory compliance, and industrial safety, this
exam serves as a definitive benchmark for professional competency in the electrical trade.
SECTION ONE: QUESTIONS 1–100
1. What is the maximum number of overcurrent devices permitted in a single lighting
and appliance branch-circuit panelboard?
A. 36
B. 42
C. 48
D. There is no longer a specific limit in the current NEC provided the panel is listed for its
use.
🟢 D. There is no longer a specific limit in the current NEC provided the panel is listed for
its use.
🔴 Explanation: Previous versions of the NEC limited panelboards to 42 overcurrent
,devices, but this restriction was removed to allow for larger panelboards that are tested
and listed for higher capacities.
2. Under the NYC Electrical Code, which of the following materials is generally
prohibited for use as a grounding electrode conductor?
A. Copper
B. Aluminum
C. Stainless Steel
D. Bare Copper
🟢 B. Aluminum
🔴 Explanation: NYC amendments often restrict the use of aluminum for grounding
electrode conductors due to concerns regarding corrosion and connectivity in the city's
specific infrastructure environments.
3. A 240-volt single-phase motor draws 20 amperes. What is the minimum size THWN
copper conductor required if the terminal pressure plates are rated for 75°C?
A. 14 AWG
B. 12 AWG
C. 10 AWG
D. 8 AWG
, 🟢 C. 10 AWG
🔴 Explanation: Per NEC Table 310.16, 12 AWG copper at 75°C is rated for 25A, but for
continuous motor loads, branch circuit conductors must be sized at 125% of the full-load
current (20A x 1.25 = 25A). However, 10 AWG is the standard selection to ensure
compliance with overcurrent protection and voltage drop considerations.
4. Which of the following describes the "accessible" (as applied to wiring methods)
definition?
A. Capable of being removed or exposed without damaging the building structure.
B. Within sight from the equipment.
C. Admitting close approach.
D. Guarded by an enclosure.
🟢 A. Capable of being removed or exposed without damaging the building structure.
🔴 Explanation: Wiring methods are considered accessible when they can be reached for
maintenance or repair without requiring the removal of permanent parts of the building
structure.
5. When installing a service disconnect, what is the maximum number of switches or
circuit breakers permitted to be used as the service disconnecting means in a single
enclosure?
