DOMAIN 1: ELECTRICAL THEORY & NATIONAL ELECTRICAL CODE (NEC)
STANDARDS
Question 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. American Society of Mechanical Engineers (ASME)
D. Occupational Safety and Health Administration (OSHA)
corrEct aNswEr: B. National Electrical Code (NEC) ✓
ratIoNalE: The National Electrical Code (NEC), published by the National Fire Protection
Association (NFPA), is the accepted standard for all electrical wiring in the United States. It is
adopted in whole or in part by most states and municipalities. NFPA is the organization that
publishes the NEC, but the code itself is the NEC. ASME governs elevator safety codes, and
OSHA regulates workplace safety.
Question 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
corrEct aNswEr: C. 15 feet ✓
ratIoNalE: NEC Article 620-32 specifies that vertical raceways must be supported at intervals
not exceeding 15 feet. This requirement ensures that raceways are adequately secured to
prevent sagging or stress on conductors.
,Question 3
What type of flex would be used to pipe a switch in a wet location?
A. Standard Flexible Metal Conduit (FMC)
B. Liquidtight Flexible Metal Conduit (LFMC)
C. Electrical Metallic Tubing (EMT)
D. Rigid Metal Conduit (RMC)
corrEct aNswEr: B. Liquidtight Flexible Metal Conduit (LFMC) ✓
ratIoNalE: Liquidtight Flexible Metal Conduit (LFMC) is specifically designed for wet locations
because it has a liquid-tight, non-metallic outer covering that prevents moisture ingress.
Standard FMC is not suitable for wet locations. EMT and RMC can be used in wet locations but
are rigid, not flexible, making them less practical for switch connections.
Question 4
What is the name for the complete metal system of duct, conduit and flex that protects the
wiring?
A. Conduit system
B. Raceway
C. Cable tray
D. Wireway
corrEct aNswEr: B. Raceway ✓
ratIoNalE: A raceway is an enclosed channel designed expressly for holding wires, cables, or
busbars. The term encompasses the complete metal system including duct, conduit, and flexible
conduit that provides mechanical protection for electrical wiring.
Question 5
How is the work divided when planning piping and wiring of an elevator installation?
A. Machine room and hoistway only
B. Hoistway, car and machine room
C. Car and counterweight only
D. Hoistway and lobby only
corrEct aNswEr: B. Hoistway, car and machine room ✓
ratIoNalE: When planning piping and wiring for an elevator installation, the work is divided
into three main areas: the hoistway (vertical shaft), the car (elevator cab), and the machine
room. This division ensures systematic installation and proper coordination between different
systems.
, Question 6
What document may be the only place to look for such information as type of fixtures, car panel,
fire service floor, etc.?
A. Blueprint
B. Job abstract
C. Specification sheet
D. Wiring diagram
corrEct aNswEr: B. Job abstract ✓
ratIoNalE: The job abstract is a critical document that contains specific project information
including type of fixtures, car panel details, fire service floor designations, and other project-
specific requirements. It serves as the primary reference for unique project specifications that
may not appear on standard drawings.
Question 7
What information is shown on a pull sheet?
A. Conduit sizes and lengths
B. Terminal connections
C. Wire colors and gauges
D. Circuit breaker ratings
corrEct aNswEr: B. Terminal connections ✓
ratIoNalE: A pull sheet (also called a termination sheet) shows the terminal connections for
wiring. It provides detailed information about where each wire connects, which is essential for
proper installation and troubleshooting.
Question 8
Which type of diagram shows a simplified path from positive to negative for all components in a
circuit?
A. Schematic diagram
B. Wiring diagram
C. Straight line diagram
D. Ladder diagram
corrEct aNswEr: C. Straight line diagram ✓
ratIoNalE: A straight line diagram shows a simplified path from positive to negative for all
components in a circuit. This type of diagram is useful for understanding basic circuit operation
without the complexity of physical layout.
