1. Which publication serves as the primary basis for electrical
installation requirements on the Washington Journeyman
Electrician Exam?
A. International Residential Code (IRC)
B. Uniform Plumbing Code (UPC)
C. National Electrical Code (NEC)
D. International Fire Code (IFC)
Rationale: The National Electrical Code (NEC) establishes the minimum
safety requirements for electrical installations. Washington
electricians are expected to understand and correctly apply the NEC
along with any applicable state amendments.
, 2. What is the primary purpose of bonding metal parts of electrical
equipment?
A. Increase circuit voltage
B. Reduce conductor resistance
C. Provide a low-impedance path for fault current
D. Improve equipment efficiency
Rationale: Bonding electrically connects conductive metal parts so
fault current has an effective path back to the source. This allows
overcurrent protective devices to operate quickly and clear faults,
reducing shock and fire hazards.
3. Which NEC chapter contains requirements for special
occupancies?
A. Chapter 2
B. Chapter 3
C. Chapter 5
D. Chapter 8
Rationale: Chapter 5 addresses special occupancies such as hazardous
locations, healthcare facilities, agricultural buildings, marinas, and
other unique environments requiring additional safety measures.
, 4. A continuous load is defined as one expected to run for at least:
A. 30 minutes
B. 1 hour
C. 2 hours
D. 3 hours or more
Rationale: The NEC defines a continuous load as one expected to
operate for three hours or more. Continuous loads require conductors
and overcurrent devices to be sized appropriately to prevent
overheating.
5. What is the minimum working space depth for equipment
operating at 0–150 volts to ground under Condition 1?
A. 24 inches
B. 36 inches
C. 42 inches
D. 48 inches
Rationale: NEC working space requirements provide adequate room
for safe operation and maintenance. For Condition 1 and voltages up
to 150 volts to ground, the minimum depth is 36 inches.
, 6. Which conductor color is commonly permitted for grounded
(neutral) conductors?
A. Green
B. Red
C. Orange
D. White
Rationale: White or gray insulation is generally used to identify
grounded conductors. Green or bare conductors are reserved for
equipment grounding conductors.
7. Equipment grounding conductors are primarily intended to:
A. Carry normal load current
B. Increase circuit efficiency
C. Carry fault current safely to facilitate overcurrent device operation
D. Reduce voltage drop
Rationale: Equipment grounding conductors normally carry no
current. During a fault, they provide a low-impedance path that
allows protective devices to disconnect power quickly.
