Exam ACTUAL EXAM COMPLETE QUESTIONS AND
CORRECT ANSWERS LATEST UPDATE THIS YEAR
SUMMARIZED EXAM COVERAGE (ALL CONTENTS COVERED)
The NYC H+H Electrician exam focuses on:
• NEC-based installation and repair requirements
• Electrical safety, arc flash protection, and lockout/tagout
• Conduit, wiring, grounding, and bonding systems
• Electrical calculations (Ohm’s law, KVA, motor sizing, voltage drop)
• Motors, starters, VFD basics, and motor troubleshooting
• Transformers, distribution systems, panelboards, feeders
• Lighting, receptacles, GFCI, emergency lighting
• Hospital emergency power systems and ATS operations
• Blueprint reading, one-line diagrams, schematics
• Troubleshooting electrical faults systematically
NYC ELECTRICIAN (NYC H+H) PRACTICE EXAM
, Page 2 of 108
Batch 1–50 (50 Questions, Continuous, Scenario-Based, ≥15 Words Each)
(MCQs in random order, answers and rationales included)
Q1
While servicing a motor control center in a hospital basement, you notice the disconnect is labeled
incorrectly. What should you do FIRST?
A. Proceed carefully and verify voltage with a meter
B. Apply lockout/tagout and confirm the correct disconnect identification before starting work
C. Ask a coworker to watch while you work live
D. Remove the incorrect label and keep working
Answer: B
Rationale: Incorrect labeling increases risk of energization. LOTO and correct identification must occur
before any servicing.
Q2
A 120-volt circuit draws 10 amps continuously for an emergency lighting load. What is the minimum
wattage consumed?
A. 12 watts
B. 120 watts
, Page 3 of 108
C. 1,200 watts
D. 10,000 watts
Answer: C
Rationale: Power equals voltage times current: P = 120 × 10 = 1,200 watts.
Q3
During troubleshooting, a breaker trips instantly when energized, even with no load connected. What is
the MOST likely cause?
A. Overload condition
B. Short circuit in wiring or breaker failure
C. Low voltage at service entrance
D. Loose neutral only
Answer: B
Rationale: Instant tripping with no load indicates a short circuit or defective breaker, not an overload.
Q4
A hospital receptacle tests “hot/neutral reversed” using a plug tester. What is the best corrective
action?
A. Replace the receptacle and recheck wiring connections for correct polarity
B. Leave it alone because equipment still works
, Page 4 of 108
C. Replace the breaker feeding the receptacle
D. Increase wire size to reduce voltage drop
Answer: A
Rationale: Reverse polarity is a serious safety issue and typically requires correcting wiring terminations
at the receptacle.
Q5
You are installing EMT conduit and need to make a three-bend saddle to clear a pipe. What is the
primary purpose of the saddle?
A. Increase conduit fill capacity
B. Raise conduit over an obstruction and return it to original alignment
C. Provide grounding continuity
D. Reduce voltage drop in branch circuits
Answer: B
Rationale: A saddle bend lifts conduit over an obstacle while maintaining the original conduit path.
Q6
A three-phase motor nameplate reads 460V, 15A, 60Hz. If measured voltage drops to 400V, what is a
likely outcome?
