1. What is the primary purpose of the National Electrical Code
(NEC)?
A. To establish electrical utility rates
B. To provide practical safeguards for persons and property from
electrical hazards
C. To regulate electrician wages
D. To determine electrical contractor licensing fees
Answer: B. To provide practical safeguards for persons and
property from electrical hazards
Rationale: The NEC is primarily a safety standard intended to protect
people and property from hazards arising from electrical
installations.
2. Which NEC article contains the general requirements for wiring
methods and materials?
A. Article 90
B. Article 100
C. Article 110
D. Article 200
Answer: C. Article 110
,Rationale: Article 110 contains requirements for electrical
installations, including examination, installation, and use of electrical
equipment.
3. Which NEC article contains definitions of many electrical terms?
A. Article 90
B. Article 100
C. Article 110
D. Article 250
Answer: B. Article 100
Rationale: Article 100 provides definitions used throughout the NEC.
4. Under the NEC, which condition generally requires electrical
equipment to be listed or labeled?
A. Only equipment over 600 volts
B. Equipment identified as requiring listing or labeling
C. Only residential equipment
D. Only temporary equipment
Answer: B. Equipment identified as requiring listing or labeling
Rationale: NEC requirements for listed or labeled equipment are
established in Article 110 and other applicable articles.
5. What is the purpose of equipment grounding and bonding?
A. Increase normal circuit voltage
B. Reduce conductor resistance
C. Provide an effective path for fault current
D. Increase motor speed
,Answer: C. Provide an effective path for fault current
Rationale: Grounding and bonding help ensure that fault current has
a low-impedance path that facilitates operation of the overcurrent
protective device.
6. Which NEC article primarily addresses grounding and bonding?
A. 200
B. 210
C. 225
D. 250
Answer: D. 250
Rationale: Article 250 contains the principal NEC requirements for
grounding and bonding.
7. Which conductor normally carries current during normal
operation in a single-phase circuit?
A. Equipment grounding conductor only
B. Grounding electrode conductor
C. Ungrounded or grounded circuit conductor, depending on circuit
arrangement
D. Grounding electrode only
Answer: C. Ungrounded or grounded circuit conductor, depending
on circuit arrangement
Rationale: Current-carrying conductors include the circuit conductors
that carry the intended load current. Equipment grounding
conductors normally carry current only during faults.
8. What is the function of an overcurrent protective device?
, A. Increase voltage
B. Open a circuit when excessive current occurs
C. Improve power factor
D. Ground the service
Answer: B. Open a circuit when excessive current occurs
Rationale: Fuses and circuit breakers protect conductors and
equipment from excessive current.
9. Which is generally considered an overcurrent condition?
A. Voltage drop only
B. Overload, short circuit, or ground fault
C. Normal motor starting current only
D. Low power factor only
Answer: B. Overload, short circuit, or ground fault
Rationale: Overcurrent includes current exceeding the ampacity of
equipment or conductors and includes overloads, short circuits, and
ground faults.
10. Which NEC article covers branch circuits?
A. Article 210
B. Article 215
C. Article 220
D. Article 225
Answer: A. Article 210
Rationale: Article 210 establishes requirements for branch circuits.
