1. Which publication is the primary standard governing electrical
installations in Michigan?
A. International Building Code (IBC)
B. International Residential Code (IRC)
C. National Electrical Code (NEC)
D. National Fire Protection Guide
Rationale: The National Electrical Code (NEC), NFPA 70, establishes the
minimum safety requirements for electrical installations throughout
the United States. Michigan adopts the NEC, along with applicable
state amendments, for electrical work. Journeyman electricians must
understand and apply the current adopted NEC during installations.
2. What is the primary purpose of the NEC?
,A. Reduce construction costs
B. Standardize electrical equipment manufacturers
C. Provide practical safeguarding of persons and property from
electrical hazards
D. Regulate utility rates
Rationale: The NEC exists to establish minimum safety requirements
designed to protect people and property from hazards arising from
the use of electricity. It is not intended as a design manual or cost-
saving document.
3. According to the NEC, electrical equipment shall be installed in
a(n):
A. Temporary manner
B. Decorative arrangement
C. Neat and workmanlike manner
D. Economical manner
Rationale: NEC 110.12 requires electrical equipment to be installed in
a neat and workmanlike manner. This ensures safe, reliable, and
professional installations that minimize hazards and facilitate
maintenance.
, 4. What is the minimum working space depth required in front of
energized equipment operating at 120 volts to ground under
Condition 1?
A. 24 inches
B. 30 inches
C. 36 inches
D. 48 inches
Rationale: NEC 110.26 specifies minimum working clearances around
electrical equipment. For 120-volt equipment under Condition 1, a
minimum depth of 36 inches provides safe access for operation and
maintenance.
5. Which conductor is intentionally connected to earth?
A. Equipment grounding conductor
B. Bonding jumper
C. Grounding electrode conductor
D. Grounded conductor
, Rationale: The grounded conductor, commonly the neutral, is
intentionally connected to earth at the service or separately derived
system. This stabilizes system voltage and provides a reference point.
6. What color is commonly used to identify equipment grounding
conductors?
A. Black
B. Red
C. White
D. Green or bare
Rationale: NEC 250.119 identifies equipment grounding conductors as
green, green with yellow stripes, or bare copper. These colors
distinguish grounding conductors from current-carrying conductors.
7. Which conductor normally carries current during normal
operation?
A. Equipment grounding conductor
B. Bonding jumper
C. Grounded conductor (neutral)
D. Grounding electrode conductor
