Coverage: NEC Articles 500-800, Fire Alarms, Solar PV, Swimming Pools, and
Health Care Facilities
1. Which NEC Article specifically covers the installation of fire alarm
systems, including wiring methods and circuit separations?
A. Article 725
B. Article 760
C. Article 800
D. Article 517
NEC Article 760 governs the installation of wiring and equipment for fire
alarm systems, distinguishing between power-limited and non-power-
limited circuits.
2. In a health care facility, what is the required testing frequency for
essential electrical systems to ensure reliability?
A. Weekly
B. Monthly
C. Quarterly
D. Annually
To ensure the safety of critical life-support equipment, NEC 517 and related
standards require monthly testing of essential electrical systems.
3. What is the minimum required distance for a pool pump motor from
the inside wall of a swimming pool?
A. 3 feet
B. 5 feet
C. 8 feet
D. 10 feet
Per NEC 680.21, pump motors must be located at least 5 feet from the
pool's edge to reduce the risk of electric shock to swimmers.
,4. Which type of PLC component is responsible for executing control
logic and processing data?
A. I/O Module
B. Power Supply
C. CPU
D. Communication Module
The Central Processing Unit (CPU) is the "brain" of the PLC, managing
data processing and executing the programmed logic.
5. What is the maximum permitted length for a flexible cord used to
connect information technology (IT) equipment?
A. 15 feet
B. 25 feet
C. 50 feet
D. 100 feet
NEC 645.5(B) limits these cords to 100 feet to prevent excessive voltage
drop and minimize overheating risks in data center environments.
6. Which NEC Article provides the requirements for the installation of
photovoltaic (PV) systems?
A. Article 680
B. Article 690
C. Article 705
D. Article 480
Article 690 covers solar PV systems, including requirements for rapid
shutdown, grounding, and overcurrent protection.
7. Emergency systems must be able to supply power to life-safety
loads within how many seconds of a power failure?
A. 10 seconds
B. 30 seconds
C. 60 seconds
D. 90 seconds
NEC 700 requires emergency systems (for life safety) to restore power
within 10 seconds, whereas legally required standby systems (Article 701)
have a 60-second window.
, 8. In a Class I, Division 1 hazardous location, which of the following is
an approved wiring method?
A. Nonmetallic-sheathed cable (Type NM)
B. Rigid Metal Conduit (RMC)
C. Electrical Nonmetallic Tubing (ENT)
D. Armored Cable (Type AC)
Class I, Division 1 locations contain flammable gases or vapors. RMC is
required because it is explosion-proof and provides high mechanical
protection.
9. What is the primary purpose of a "Hot Aisle Containment" system
in a data center?
A. Fire suppression
B. Equipment security
C. Energy efficiency through air isolation
D. Noise reduction
This method isolates hot exhaust air from cold intake air, preventing them
from mixing and significantly improving cooling efficiency.
10. Which device is specifically designed to protect a motor from
sustained overcurrent conditions by disconnecting power when
excessive heat is detected?
A. Fuse
B. Circuit Breaker
C. Overload Relay
D. Ground Fault Protector
Unlike standard breakers, overload relays are tailored to follow a motor's
heating curve to prevent damage during prolonged over-current scenarios.
11. What is the minimum burial depth for a direct-buried control cable
for a residential lawn sprinkler system rated at 30 volts or less?
A. 6 inches
B. 12 inches
C. 18 inches
D. 24 inches
According to NEC Table 300.5, Column 5, circuits operating at 30 volts or
less and installed in a residential location require a minimum cover of 6
inches.
