1. What is the primary purpose of NFPA 110?
A. To regulate electrical distribution in homes
B. To ensure the reliability of emergency and standby power
systems
C. To design lighting systems
D. To enforce general building codes
B. To ensure the reliability of emergency and standby power
systems
NFPA 110 provides requirements to ensure emergency and standby
power systems operate reliably when needed.
2. Which level of emergency power supply is required to
automatically start and supply power to critical systems within
10 seconds?
A. Level 1
B. Level 2
C. Level 3
D. Level 4
A. Level 1
Level 1 systems are required for life-safety and critical loads and
must start automatically within 10 seconds.
, 3. NFPA 110 defines a “rated load” as:
A. The maximum load a system can handle indefinitely
B. The load that the system is designed to serve continuously
for a specified period
C. The load applied only during testing
D. The minimum load necessary for operation
B. The load that the system is designed to serve continuously for a
specified period
Rated load is the load a system must reliably supply for a defined
emergency duration.
4. How often should Level 1 emergency generators be tested
under load according to NFPA 110?
A. Monthly
B. Weekly
C. Annually
D. Every 5 years
A. Monthly
NFPA 110 requires Level 1 generators to undergo monthly load
testing to ensure reliability.
5. What type of fuel is commonly used in standby generators for
hospitals?
A. Gasoline
B. Diesel
C. Coal
D. Wood
B. Diesel
Diesel fuel is preferred due to its energy density, storage stability,
and reliability.
, 6. Which of the following is a required feature of emergency
power systems?
A. Remote monitoring only
B. Automatic transfer switch
C. Manual start only
D. Low-voltage operation
B. Automatic transfer switch
An automatic transfer switch ensures critical loads are transferred
to backup power without manual intervention.
7. NFPA 110 requires emergency power systems to be capable of
operating for a minimum of:
A. 15 minutes
B. 30 minutes
C. 2 hours
D. The duration necessary to maintain critical operations
D. The duration necessary to maintain critical operations
Emergency systems must provide power long enough to sustain
essential functions until normal power is restored.
8. What is the minimum frequency for exercising a Level 2 system?
A. Daily
B. Monthly
C. Annually
D. Every 5 years
C. Annually
Level 2 systems, which are non-life-safety, require annual testing
unless otherwise specified.
9. NFPA 110 requires a written maintenance program for:
A. Only diesel generators
, B. All emergency and standby power systems
C. Only natural gas generators
D. Only systems serving Level 1 loads
B. All emergency and standby power systems
A formal maintenance program ensures all systems operate reliably
when needed.
10. Which class of transfer switch is designed to operate
automatically and can also be manually operated?
A. Class A
B. Class B
C. Class C
D. Class D
C. Class C
Class C transfer switches allow automatic and manual operation for
flexibility in emergencies.
11. NFPA 110 defines a “critical load” as:
A. Loads that affect comfort only
B. Loads that must remain operational during emergencies
C. Loads that can be temporarily turned off
D. Loads for nonessential equipment
B. Loads that must remain operational during emergencies
Critical loads are those essential to life safety, emergency
operations, or protection of property.
12. How often should fuel oil storage tanks for emergency
generators be inspected?
A. Every week
B. Monthly
