Candidate Instructions:
This examination evaluates the candidate’s technical knowledge, practical application,
and code compliance skills required for electrical work within New York City. The test
consists of approximately 80 multiple-choice questions covering electrical theory,
National Electrical Code (NEC), NYC amendments, safety practices, and system design.
,Read each question carefully and select the best answer. Calculators are permitted unless
otherwise specified. No reference materials are allowed. Ensure all answers are recorded
clearly. Time management is critical—allocate approximately 2 minutes per question.
Disclaimer:
This is an original simulation designed for preparation purposes and is not an official
DCAS examination.
This assessment is intended to measure competency in electrical installation,
maintenance, troubleshooting, and code compliance in commercial and residential
environments. Candidates are expected to demonstrate strong analytical skills,
understanding of electrical systems, and adherence to safety standards.
Core Competency Areas:
Electrical Theory and Calculations
National Electrical Code (NEC) Compliance
NYC Electrical Code Amendments
Wiring Methods and Materials
Grounding and Bonding
Motors and Controls
, Safety Regulations and OSHA Standards
Blueprint Reading and Load Calculations
Q1. A commercial building requires feeder conductors supplying a load of 180A
continuous and 40A non-continuous. What is the minimum ampacity rating required for
the feeder conductors?
A. 200A
B. 225A
C. 250A
D. 180A
Correct Answer: 🔴 B. 225A
Explanation: 🟡 Continuous loads must be multiplied by 125% (180A × 1.25 = 225A), then
add non-continuous load (40A), but feeder sizing must meet or exceed 225A as minimum
conductor ampacity. Option A is insufficient; C is oversized; D ignores NEC continuous load
requirement.
Q2. In a grounded electrical system, what is the primary purpose of bonding metal
enclosures?
A. Increase resistance
, B. Prevent overheating
C. Provide a low-impedance fault path
D. Reduce voltage drop
Correct Answer: 🔴 C. Provide a low-impedance fault path
Explanation: 🟡 Bonding ensures fault current flows efficiently to trip protective devices. A is
incorrect as resistance should be minimized; B is indirect; D relates to conductor sizing, not
bonding.
Q3. A 3-phase, 208V system supplies a 10 kW balanced load. What is the approximate line
current?
A. 27.8A
B. 34.7A
C. 48.1A
D. 60.0A
Correct Answer: 🔴 A. 27.8A
Explanation: 🟡 Use formula: I = P / (√3 × V) = 10,000 / (1.732 × 208) ≈ 27.8A. Other
options reflect incorrect formulas or rounding errors.
