NYC ELECTRICIAN (NYC H+H)
EXAMINATION COMPLETE QUESTIONS
AND DETAILED SOLUTIONS LATEST
UPDATE THIS YEAR JUST RELEASED
The NYC Electrician (NYC Health + Hospitals)
examination typically evaluates the knowledge, skills, and
judgment required for electricians working in healthcare
facilities. Questions commonly assess electrical theory,
electrical distribution systems, transformers, motors,
generators, emergency power systems, National Electrical
Code (NEC) requirements, workplace safety,
troubleshooting, preventive maintenance, electrical
drawings, healthcare facility standards, and practical field
applications. Candidates are expected to apply technical
knowledge to real-world maintenance and repair scenarios
encountered in hospitals and healthcare environments.
Exam Coverage
Electrical theory fundamentals – voltage, current,
resistance, power calculations, and circuit analysis.
, NEC requirements – code-compliant installations and
maintenance procedures.
Electrical safety – lockout/tagout, arc-flash
protection, and PPE requirements.
Transformers – operation, troubleshooting, and
maintenance.
Motors and motor controls – starting methods,
overload protection, and diagnostics.
Emergency power systems – generators, transfer
switches, and backup power operations.
Healthcare facility electrical systems – critical branch
and life-safety branch requirements.
Electrical distribution systems – switchgear, panels,
feeders, and branch circuits.
Electrical drawings and schematics – interpretation
and troubleshooting.
Grounding and bonding – personnel and equipment
protection.
Lighting systems – maintenance, controls, and energy
efficiency.
Test instruments – proper use of multimeters, clamp
meters, and megohmmeters.
, Batteries and UPS systems – inspection and
maintenance.
Preventive maintenance – inspections, testing, and
documentation.
Troubleshooting techniques – identifying and
correcting electrical faults.
Fire alarm interface systems – electrical requirements
and coordination.
Conduit and wiring methods – installation standards
and repairs.
Hospital electrical reliability – minimizing service
interruptions.
Occupational safety requirements – hazard
recognition and compliance.
Electrical calculations – demand loads, conductor
sizing, and circuit capacities.
1.
While troubleshooting a hospital air-handling unit, an
electrician measures 480 volts at the motor starter line side
but no voltage at the load side when the starter is
energized. What is the most likely cause?
, A. Defective overload relay contacts
B. Open disconnect switch upstream
C. Faulty voltmeter leads
D. Low motor insulation resistance
Answer: A
Rationale: Voltage present on the line side but absent on
the load side indicates interruption within the starter,
commonly caused by an open overload relay or failed
contact.
2.
A maintenance electrician must lock out a 277-volt
lighting circuit before replacing fixtures. What should
occur immediately after applying the lockout device?
A. Replace fixtures immediately
B. Verify absence of voltage using approved testing
equipment
C. Remove circuit breaker handle
D. Notify only coworkers nearby
Answer: B
Rationale: Verification of de-energization is a critical
lockout/tagout step before work begins.
