1. In Evansville, Indiana, an electrical contractor performing
installations subject to the Indiana Electrical Code must primarily
use which nationally recognized standard as the technical basis for
electrical installation requirements?
A. International Mechanical Code
B. International Plumbing Code
C. National Electrical Code (NFPA 70)
D. International Energy Conservation Code
The National Electrical Code (NFPA 70) provides the principal technical
requirements incorporated into Indiana’s electrical regulations, subject
to Indiana amendments and applicable local requirements.
2. A contractor is installing a 120/240-volt, single-phase dwelling
service. Which conductor is normally permitted to serve as the
grounded conductor when properly sized and installed?
A. Equipment grounding conductor
B. Neutral conductor
,C. Bonding jumper only
D. Grounding electrode conductor only
The neutral conductor is the grounded circuit conductor that carries
unbalanced current in a 120/240-volt single-phase system and is distinct
from the equipment grounding conductor.
3. What is the primary purpose of an equipment grounding
conductor?
A. To carry normal neutral current
B. To increase circuit voltage
C. To provide additional circuit capacity
D. To provide a low-impedance path for fault current
An equipment grounding conductor provides a low-impedance path for
fault current so that the overcurrent protective device can operate
promptly during a fault.
4. A 20-ampere branch circuit is being installed using copper
conductors. Under ordinary conditions, which conductor size is
generally associated with a 20-ampere circuit?
A. 16 AWG
B. 12 AWG
C. 10 AWG
D. 8 AWG
,12 AWG copper is the standard minimum conductor size commonly
associated with a 20-ampere branch circuit, subject to the applicable
NEC conditions and adjustment requirements.
5. What is the principal function of a circuit breaker?
A. To regulate power-factor correction
B. To increase available voltage
C. To protect conductors and equipment from excessive current
D. To replace the grounding electrode system
A circuit breaker opens the circuit when excessive current occurs, helping
protect conductors and connected equipment from overheating and
damage.
6. A continuous load is a load expected to operate at maximum
current for how long?
A. At least 30 minutes
B. At least 1 hour
C. Three hours or more
D. Six hours or more
For NEC load calculations, a continuous load is one where the maximum
current is expected to continue for three hours or more.
7. When calculating the ampacity required for a branch circuit
supplying a continuous load, the continuous portion of the load is
generally multiplied by what factor?
, A. 80%
B. 125%
C. 150%
D. 200%
The NEC generally requires continuous loads to be calculated at 125
percent of their maximum current when sizing conductors and
overcurrent protection.
8. What is the primary purpose of a grounding electrode system?
A. To provide the normal return path for branch-circuit current
B. To increase receptacle capacity
C. To replace equipment grounding conductors
D. To connect the electrical system to earth for grounding and related
fault and surge functions
The grounding electrode system establishes a connection between the
electrical system and earth and performs important grounding and
voltage-stabilization functions.
9. Which device is specifically designed to provide additional
protection against electric shock from ground-fault current?
A. Standard fuse
B. Surge arrester
C. Ground-fault circuit interrupter (GFCI)
D. Transformer
