deal) .


Question 1
According to NEC 300.4, what is the minimum clearance required from the edge of a wood stud
to the edge of a hole bored for nonmetallic-sheathed cable?
A) 1/2 inch
B) 1 inch
C) 1 1/4 inches
D) 1 1/2 inches
Correct Answer: C) 1 1/4 inches
Rationale: NEC 300.4(A)(1) requires that holes in wood studs be bored so that the edge of the
hole is not less than 1 1/4 inches from the nearest edge of the wood member.

Question 2
What is the minimum required separation between a Class 1 fire alarm circuit conductor and a
Class 2 or Class 3 circuit conductor when they are not in a raceway?
A) No separation is required.
B) 1/4 inch
C) 1/2 inch
D) 2 inches
Correct Answer: B) 1/4 inch
Rationale: To prevent interference, Class 1 circuits must be separated from Class 2 and Class 3
circuits by at least 0.25 inches (1/4 inch).

Question 3
A basic fire alarm system is required by code to have how many independent power sources?
A) 1
B) 2
C) 3
D) 4
Correct Answer: B) 2

,Rationale: Fire alarm systems require a primary power source (usually commercial AC power)
and a secondary power source (such as batteries or a generator) to ensure operation during a
power failure.

Question 4
What is the minimum required clearance between an uninsulated 250-volt electrical line and a
receiving antenna?
A) 1 Foot
B) 2 Feet
C) 3 Feet
D) 6 Feet
Correct Answer: B) 2 Feet
Rationale: NEC 810.13 specifies a minimum clearance of 2 feet between receiving antennas
and open conductors of electric light or power circuits not exceeding 250 volts.

Question 5
According to NEC 800.44(A)(4), what is the minimum separation distance that must be
maintained between communications cables and electric, light, or power conductors?
A) 1/4 inch
B) 1 inch
C) 2 inches
D) 6 inches
Correct Answer: C) 2 inches
Rationale: A minimum separation of 2 inches must be maintained between communication
cables and power conductors to prevent electrical interference and potential hazards.

Question 6
What is the maximum flash rate for a fire alarm strobe light, as specified by NFPA 72?
A) 1 flash per second
B) 2 flashes per second
C) 3 flashes per second

,D) 4 flashes per second
Correct Answer: B) 2 flashes per second
Rationale: NFPA 72 18.5.2.1 limits the maximum flash rate to two flashes per second (2 Hz) to
prevent triggering photosensitive seizures.

Question 7
According to NFPA 72, a voice alarm system must repeat an evacuation message a minimum of
how many times?
A) 1
B) 2
C) 3
D) 4
Correct Answer: B) 2
Rationale: NFPA 72 24.4.1.2.1 requires that a voice message for evacuation be repeated at
least two times to ensure occupants hear and understand the instructions.

Question 8
What is the minimum required mounting height from the floor to the activating part of a
manual fire alarm pull station?
A) 3 feet (36 inches)
B) 3 1/2 feet (42 inches)
C) 4 feet (48 inches)
D) 5 feet (60 inches)
Correct Answer: B) 3 1/2 feet (42 inches)
Rationale: To be accessible, the operable part of a manual pull station must be located at least
42 inches and not more than 48 inches above the finished floor.

Question 9
An overhead feeder conductor must have a minimum clearance of how many feet from
chimneys, radio, and television antennas?
A) 1 Foot

, B) 2 Feet
C) 3 Feet
D) 5 Feet
Correct Answer: C) 3 Feet
Rationale: NEC 225.19(B) requires overhead conductors to have a vertical clearance of not less
than 3 feet above or below building features like antennas.

Question 10
The National Electrical Code (NEC) defines a "Continuous Load" as a load where the maximum
current is expected to continue for how many hours or more?
A) 1 hour
B) 2 hours
C) 3 hours
D) 8 hours
Correct Answer: C) 3 hours
Rationale: The NEC defines a continuous load as one that runs at its maximum current for 3
hours or more. This is important for calculating conductor and overcurrent protection sizes.

Question 11
What is the minimum required headroom of working space above service equipment or
panelboards?
A) 6 feet
B) 6 feet, 3 inches
C) 6.5 feet (6 feet, 6 inches)
D) 7 feet
Correct Answer: C) 6.5 feet (6 feet, 6 inches)
Rationale: The NEC requires a minimum headroom of 6.5 feet, or the height of the
equipment, whichever is greater, in the working space around electrical equipment.
