Introduction
This examination is designed to evaluate the apprentice or journey-level
elevator mechanic's mastery of electrical theory, elevator systems, and
code compliance. It assesses the ability to apply NEC Article 620, diagnose
motor control issues, and safely maintain elevator equipment. The
examination utilizes multiple-choice and scenario-based items to evaluate
critical thinking and technical decision-making. Emphasis is placed on real-
world application, safety circuits, and systematic troubleshooting. Success
demonstrates readiness for journey-level practice in the elevator industry.
SECTION ONE: QUESTIONS 1–100
1. What is the name of the code that is the accepted standard for all
electrical wiring in the United States?
,A. National Fire Protection Association (NFPA)
B. National Electrical Code (NEC)
C. Occupational Safety and Health Administration (OSHA)
D. American National Standards Institute (ANSI)
B. National Electrical Code (NEC)
RATIONALE: The NEC, published by the NFPA as NFPA 70, is the
accepted standard for electrical wiring in the United States and is adopted
by most jurisdictions.
2. What is the maximum distance between supports of a vertical
raceway, based on NEC Article 620-32?
A. 10 feet
B. 12 feet
C. 15 feet
D. 20 feet
C. 15 feet
RATIONALE: NEC Article 620-32 requires vertical raceways to be
supported at intervals not exceeding 15 feet to prevent sagging and stress
on conductors.
3. Once an SCR is gated, how long does it continue to conduct?
A. Until the gate signal is removed
B. Until the AC sine wave passes through zero
C. Indefinitely once triggered
D. Until the current exceeds the rating
B. Until the AC sine wave passes through zero
RATIONALE: An SCR turns off when current drops below holding
current, which naturally occurs at the zero-crossing point of the AC
waveform.
4. What type of flex would be used to pipe a switch in a wet location?
,A. Greenfield (flexible metal conduit)
B. Liquidtight Flexible Conduit (LFMC)
C. Electrical Metallic Tubing (EMT)
D. Rigid Metal Conduit (RMC)
B. Liquidtight Flexible Conduit (LFMC)
RATIONALE: LFMC is designed for wet locations and provides a
liquidtight enclosure for conductors.
5. How can you reverse the direction of a three-phase AC motor?
A. Reverse the polarity of the DC supply
B. Interchange any 2 leads
C. Increase the voltage
D. Change the frequency
B. Interchange any 2 leads
RATIONALE: Interchanging any two of the three power leads changes
the phase rotation, reversing the rotating magnetic field and motor
direction.
6. What is the metal enclosure that furnishes protection for electrical
wire called?
A. Conduit
B. Raceway
C. Junction box
D. Cable tray
B. Raceway
RATIONALE: A raceway is the complete system of conduit and flex that
protects electrical wiring. Conduit is a type of raceway.
7. Which of the following describes how an SCR is turned OFF?
A. The gate signal is removed
B. Voltage is removed from anode to cathode
, C. The current is increased beyond the rating
D. A reverse gate pulse is applied
B. Voltage is removed from anode to cathode
RATIONALE: An SCR turns off when current through it drops below the
holding current, which occurs when anode-cathode voltage is removed or
the AC waveform crosses zero.
8. What is the approximate density of cast iron?
A. 2.7 g/cm³
B. 7.2 g/cm³
C. 8.9 g/cm³
D. 11.3 g/cm³
B. 7.2 g/cm³
RATIONALE: Cast iron has an approximate density of 7.2 g/cm³, a
standard property used in counterweight calculations.
9. What is the minimum overhead clearance for raceways mounted in
the machine room overhead?
A. 6 feet
B. 7 feet
C. 8 feet
D. 9 feet
B. 7 feet
RATIONALE: The minimum overhead clearance for raceways in the
machine room is 7 feet, providing adequate clearance for maintenance
personnel.
10. A brake coil has an inductance of 4 henries. If the coil is placed
into a circuit with an operating frequency of 60 Hz, what is the coil's
reactance?
