Introduction
The North Carolina Elevator Specialist licensure examination serves to verify the competency and
technical proficiency of professionals engaged in the installation, maintenance, alteration, and repair of
vertical transportation systems. This comprehensive evaluation assesses essential knowledge of
electrical theory, mechanical interfaces, and rigorous safety codes governing conveyance equipment.
Candidates must demonstrate proficiency through a combination of direct knowledge questions and
practical, scenario-based inquiries. The assessment places significant emphasis on real-world
application, hazard identification, and precise decision-making to ensure absolute compliance with
regulatory standards and public safety mandates.
What is the primary safety function of the car door interlock on an electric elevator?
A. To prevent the car from moving unless all hoistway doors are closed and locked
,B. To supply continuous 120V power to the car lighting circuit
C. To activate the emergency brake in the event of an overspeed condition
D. To monitor the position of the counterweight in the pit
🟢 A. To prevent the car from moving unless all hoistway doors are closed and locked
🔴 RATIONALE: The car door interlock and hoistway door switch combination ensures the
elevator cannot operate unless every landing door is securely closed and locked, preventing falls
into the hoistway.
Which standard specifically governs the safety code for elevators, escalators, and moving walks?
A. NFPA 70
B. ASME A17.1
C. OSHA 1910
D. ANSI A117.1
🟢 B. ASME A17.1
🔴 RATIONALE: ASME A17.1 is the accepted national safety code standard for the design,
construction, installation, operation, inspection, testing, maintenance, and alteration of elevators
and escalators.
In a standard three-phase AC motor circuit for a traction elevator, what happens if one phase is lost
while the motor is running?
A. The motor speed doubles to compensate
B. Current draw on the remaining phases increases significantly, risking motor burnout
C. The drive automatically switches to DC battery backup
D. The governor engages the mechanical safety brakes immediately
🟢 B. Current draw on the remaining phases increases significantly, risking motor burnout
🔴 RATIONALE: Single-phasing causes a three-phase motor to draw excessive current through
,the remaining energized windings, leading to severe overheating and potential winding failure if
thermal overloads do not trip.
What is the minimum clearance required in front of elevator controller cabinets as specified by the
National Electrical Code (NEC)?
A. 24 inches
B. 30 inches
C. 36 inches
D. 48 inches
🟢 C. 36 inches
🔴 RATIONALE: The NEC mandates a minimum clear working space depth of 36 inches in front of
electrical equipment operating at low voltage to allow safe access for technicians.
When performing a static load test on a hydraulic elevator, where is the pressure gauge installed?
A. Directly on the plunger head inside the car
B. Between the pump unit and the control valve assembly
C. Inside the oil reservoir tank
D. At the main line shut-off valve port
🟢 B. Between the pump unit and the control valve assembly
🔴 RATIONALE: Installing a pressure gauge between the pump and the control valve allows
accurate measurement of system operating and static pressures during testing procedures.
Which device is designed to stop the elevator car by gripping the guide rails in the event of an
uncontrolled downward overspeed?
A. Buffer spring
B. Governor safety gear
C. Terminal slow-down switch
D. Emergency stop button
, 🟢 B. Governor safety gear
🔴 RATIONALE: The governor detects overspeed and trips the mechanical safety mechanism,
causing safeties to clamp onto the guide rails and bring the car to a controlled stop.
What color insulation is strictly designated for grounded circuit conductors (neutral wires) under the
NEC?
A. Green or bare copper
B. White or natural gray
C. Red or black
D. Yellow or orange
🟢 B. White or natural gray
🔴 RATIONALE: The NEC specifies white or natural gray insulation for grounded neutral
conductors in electrical distribution systems up to certain gauges.
A technician measures a resistance of zero ohms between an ungrounded conductor and the metal
conduit. What condition does this indicate?
A. High resistance splice
B. Open circuit
C. Ground fault or short circuit to ground
D. Normal operating impedance
🟢 C. Ground fault or short circuit to ground
🔴 RATIONALE: Zero resistance (continuity) between a hot conductor and a grounded metal
raceway signifies an insulation failure resulting in a ground fault.
What is the primary purpose of the elevator pit stop switch?
A. To reset the logic controller after an error code
B. To allow maintenance personnel to safely disable elevator movement while working in the pit
