1. The primary purpose of the National Electrical Code (NEC) is to:
A. Ensure uniform contractor licensing
B. Regulate utility company operations
C. Safeguard persons and property from electrical hazards
D. Standardize electrical material pricing
Answer: C
The NEC’s stated purpose is safety-related, focusing on preventing
electrical hazards to people and property rather than regulating business
or pricing.
2. Which organization publishes the National Electrical Code?
A. OSHA
B. National Fire Protection Association (NFPA)
C. IEEE
D. Department of Energy
Answer: B
The NEC is published and updated by the NFPA and adopted by
jurisdictions such as Kansas.
3. How often is the NEC updated?
A. Every year
B. Every two years
, C. Every three years
D. Every five years
Answer: C
The NEC follows a three-year revision cycle to address new technologies
and safety issues.
4. For a limited electrical contractor, work is typically restricted to:
A. All commercial and industrial installations
B. Utility transmission systems
C. Specific voltage or system limitations defined by the license
D. Design of electrical systems only
Answer: C
Limited licenses restrict the scope of work to defined systems, voltages, or
occupancies as set by the state or local authority.
5. Which conductor is intentionally connected to earth at the service?
A. Equipment grounding conductor
B. Ungrounded (hot) conductor
C. Grounded (neutral) conductor
D. Bonding jumper
Answer: C
The grounded (neutral) conductor is connected to earth to stabilize system
voltage and reduce shock hazards.
6. Grounding and bonding are required primarily to:
A. Reduce electricity costs
B. Increase system efficiency
C. Provide a low-impedance path for fault current
D. Improve lighting quality
Answer: C
A low-impedance fault path ensures overcurrent devices operate quickly to
clear faults.
, 7. What color insulation is typically used for grounded conductors?
A. Green
B. Red
C. White or gray
D. Black
Answer: C
The NEC identifies grounded conductors by white or gray insulation to
distinguish them from ungrounded conductors.
8. Equipment grounding conductors are identified by:
A. White insulation
B. Green or bare copper
C. Blue insulation
D. Yellow insulation
Answer: B
Green or bare conductors are reserved exclusively for equipment
grounding to avoid confusion.
9. A circuit breaker primarily protects against:
A. Voltage drop
B. Overcurrent conditions
C. Poor grounding
D. Power factor issues
Answer: B
Circuit breakers open the circuit during overloads or short circuits to
prevent overheating and fire.
10. What NEC article covers general requirements for wiring
methods?
A. Article 100
B. Article 110
C. Article 300
D. Article 400
