NYC DCAS Electrician Practice Questions (1 to 40)
Question 1
A 3-phase, 460-volt, 50-horsepower continuous-duty squirrel-cage
motor has a full-load current rating of 65 Amperes. What is the minimum
required ampacity for the motor branch-circuit conductors?
A) 65 Amperes
B) 75 Amperes
C) 81.25 Amperes
,D) 162.5 Amperes
VERIFIED UPDATED ANSWER: C) 81.25 Amperes
RATIONALE: According to NEC Article 430.22, conductors supplying a
single motor used for continuous duty must have an ampacity of not
less than 125% of the motor's full-load current rating. Multiplying 65
Amperes by 1.25 yields exactly 81.25 Amperes.
Question 2
Which of the following elements is a mandatory requirement under the
NYC Electrical Code Amendments when installing electrical metallic tubing
(EMT) in wet locations?
A) Standard set-screw couplings are permitted if wrapped in electrical
tape.
B) All couplings and connectors must be listed as threadless.
C) All couplings and connectors must be listed as rain-tight or wet-
location type.
D) Only scheduled 80 PVC is allowed in damp environments.
VERIFIED UPDATED ANSWER: C) All couplings and connectors must be
listed as rain-tight or wet-location type.
RATIONALE: NEC Article 358.42 specifies that where EMT is installed
in wet locations, all couplings and connectors must be securely
made up and explicitly listed for use in rain-tight or wet-location
configurations to prevent water entry.
Question 3
What is the maximum allowable number of 10 AWG THHN copper
,conductors that can be legally installed inside a 1-inch Electrical Metallic
Tubing (EMT) run?
A) 12
B) 16
C) 22
D) 26
VERIFIED UPDATED ANSWER: B) 16
RATIONALE: According to NEC Annex C, Table C.1 (Conduit and Tubing
Fill for Conductors of the Same Size), the maximum number of 10
AWG THHN conductors permitted inside a 1-inch EMT run is 16 based
on the standard 40% cross-sectional area fill rule.
Question 4
When calculating service-entrance conductors for a dwelling unit, what is
the standard demand factor applied to the first 3,000 volt-amperes of the
general lighting and receptacle load?
A) 35%
B) 50%
C) 75%
D) 100%
VERIFIED UPDATED ANSWER: D) 100%
RATIONALE: NEC Table 220.42 specifies that the first 3,000 volt-
amperes of a dwelling unit's lighting and general receptacle load
must be calculated at a 100% demand factor. Portions of the load
from 3,001 to 120,000 volt-amperes are calculated at 35%.
, Question 5
A 240-volt single-phase branch circuit supplies a continuous resistive
heating load of 4,800 Watts. What is the minimum required rating for the
overcurrent protective device (OCPD)?
A) 20 Amperes
B) 25 Amperes
C) 30 Amperes
D) 40 Amperes
VERIFIED UPDATED ANSWER: B) 25 Amperes
RATIONALE: The continuous load current is calculated as Power /
Voltage: 4,800W / 240V = 20 Amperes. NEC Article 210.20(A)
requires the overcurrent protective device for continuous loads to
be rated at no less than 125% of the continuous load. Therefore, 20A
× 1.25 = 25 Amperes.
Question 6
What is the minimum size copper equipment grounding conductor (EGC)
required for a branch circuit protected by a 40-ampere circuit breaker?
A) 14 AWG
B) 12 AWG
C) 10 AWG
D) 8 AWG
VERIFIED UPDATED ANSWER: C) 10 AWG
RATIONALE: According to NEC Table 250.122, the minimum size copper
equipment grounding conductor required for an overcurrent
