1. Under which Indiana Administrative Code section is the Indiana Electrical
Code established?
A. 675 IAC 16
B. 675 IAC 17
C. 675 IAC 18
D. 675 IAC 19
Answer: B. 675 IAC 17
Rationale: Indiana Electrical Code requirements are contained in 675 IAC 17. Other
sections address areas such as plumbing, mechanical systems, and energy
conservation.
2. The currently effective Indiana Electrical Code is based on which edition of
NFPA 70?
A. 2005 NEC
B. 2011 NEC
C. 2008 NEC
D. 2014 NEC
Answer: C. 2008 NEC
Rationale: Indiana's currently effective 675 IAC 17-1.8 adopts the 2008 National
Electrical Code with Indiana amendments.
,3. Which organization publishes the National Electrical Code?
A. OSHA
B. ICC
C. IEEE
D. NFPA
Answer: D. NFPA
Rationale: The National Electrical Code, or NFPA 70, is published by the National
Fire Protection Association.
4. What is the primary purpose of the National Electrical Code?
A. Establish electrical safety requirements
B. Set electrical equipment retail prices
C. Determine contractor profit margins
D. Establish utility billing rates
Answer: A. Establish electrical safety requirements
Rationale: The NEC establishes minimum safety requirements for electrical
installations to help protect people and property from electrical hazards.
5. In Indiana, who should a contractor contact to determine local electrical
licensing requirements?
A. The local authority having jurisdiction
B. The nearest electrical manufacturer
C. The federal tax office
D. The material supplier
Answer: A. The local authority having jurisdiction
Rationale: Electrical contractor licensing is generally regulated locally in Indiana.
The responsible city or county authority can provide the applicable licensing,
registration, and permit requirements.
6. What is the primary purpose of an electrical permit?
A. Establish the contractor's profit
B. Authorize regulated electrical work and facilitate inspection
,C. Guarantee the equipment warranty
D. Determine the electrical utility's rates
Answer: B. Authorize regulated electrical work and facilitate inspection
Rationale: A required electrical permit provides governmental authorization for
regulated work and allows the authority having jurisdiction to verify compliance.
7. What is the main purpose of an overcurrent protective device?
A. Increase circuit voltage
B. Protect conductors and equipment from excessive current
C. Increase motor speed
D. Reduce conductor resistance
Answer: B. Protect conductors and equipment from excessive current
Rationale: Fuses and circuit breakers limit the effects of excessive current caused
by overloads, short circuits, or ground faults as applicable.
8. Which device is designed to interrupt current automatically when excessive
current flows through a circuit?
A. Circuit breaker
B. Transformer
C. Receptacle
D. Disconnect handle only
Answer: A. Circuit breaker
Rationale: A circuit breaker is an overcurrent protective device that automatically
opens a circuit when its operating conditions exceed its rated limits.
9. What is the primary function of a fuse?
A. Increase available fault current
B. Interrupt excessive current by opening the circuit
C. Regulate utility voltage
D. Provide mechanical support for conductors
Answer: B. Interrupt excessive current by opening the circuit
, Rationale: A fuse contains a current-responsive element that opens when
excessive current causes the element to operate, interrupting the circuit.
10. Which conductor normally carries current back to the source in a single-
phase circuit?
A. Equipment grounding conductor
B. Grounding electrode conductor
C. Grounded conductor
D. Bonding jumper
Answer: C. Grounded conductor
Rationale: In a typical single-phase system, the grounded conductor, commonly
called the neutral, provides the return path for unbalanced or line-to-neutral
current.
11. What is the primary purpose of an equipment grounding conductor?
A. Carry normal load current continuously
B. Provide a low-impedance fault-current path
C. Increase circuit voltage
D. Replace overcurrent protection
Answer: B. Provide a low-impedance fault-current path
Rationale: The equipment grounding conductor provides a path for fault current
so that the overcurrent protective device can operate and disconnect the faulted
circuit.
12. What is the primary purpose of bonding electrically conductive equipment
together?
A. Establish electrical continuity between conductive parts
B. Increase conductor ampacity
C. Reduce utility consumption
D. Increase system frequency
Answer: A. Establish electrical continuity between conductive parts
