1. A commercial building is submitted for permit review with
electrical plans showing a 480Y/277-volt, 3-phase, 4-wire service.
During the plans examination, what is the primary responsibility of
the electrical plans examiner regarding the service design?
A. Install the service conductors
B. Verify compliance with the adopted electrical code and approved
construction documents
C. Approve utility company service routing
D. Perform final field inspections
Answer: B
Rationale: The primary responsibility of an ICC Electrical Plans
Examiner is to review submitted construction documents for compliance
with the adopted electrical code before construction begins. Installation,
utility routing, and field inspections are outside the primary scope of
plan review.
2. According to the NEC, what is the principal purpose of overcurrent
protection?
A. Increase equipment efficiency
B. Protect conductors and equipment from excessive current
1
,C. Improve power factor
D. Reduce voltage drop
Answer: B
Rationale: Overcurrent protective devices are intended to protect
conductors and equipment from overloads, short circuits, and ground
faults where applicable. Their purpose is not to improve efficiency or
voltage regulation.
3. During review of branch-circuit calculations, a continuous lighting
load equals 80 amperes. What minimum ampere rating must the
branch circuit be designed for?
A. 80 A
B. 90 A
C. 100 A
D. 125 A
Answer: C
Rationale: Continuous loads must be calculated at 125% unless the
equipment is listed for continuous operation at 100%. Eighty amperes ×
125% = 100 amperes.
4. What is the minimum working space depth in front of energized
equipment operating at 480 volts to ground under typical
Condition 2?
A. 3 feet
B. 3.5 feet
C. 4 feet
D. 5 feet
Answer: C
2
,Rationale: Working clearances depend on voltage and conditions. For
151–600 volts under Condition 2, the minimum depth is 4 feet.
5. A plans examiner discovers that panelboards are installed inside
clothes closets. What should be the proper response?
A. Approve because maintenance access exists
B. Approve if GFCI protection is installed
C. Reject because overcurrent devices are prohibited in clothes closets
D. Approve only for residential occupancies
Answer: C
Rationale: The NEC prohibits overcurrent devices in clothes closets
because of fire hazards and limited accessibility.
6. Which NEC article primarily governs grounding and bonding
requirements?
A. Article 210
B. Article 250
C. Article 300
D. Article 430
Answer: B
Rationale: Article 250 contains comprehensive requirements for
grounding, bonding, grounding electrode systems, equipment grounding
conductors, and bonding jumpers.
7. During load calculations, which load is generally permitted to be
reduced using demand factors?
3
, A. Fire pump load
B. Emergency system load
C. General lighting load
D. Ground-fault protection load
Answer: C
Rationale: General lighting loads are often eligible for demand factors
under Article 220. Fire pumps and emergency loads generally require
full consideration.
8. Which occupancy generally requires GFCI protection for
receptacles serving countertop surfaces?
A. Storage warehouse
B. Office conference room
C. Dwelling unit kitchen
D. Mechanical room
Answer: C
Rationale: Kitchen countertop receptacles in dwelling units require
GFCI protection because of the increased risk of electrical shock near
water.
9. During plan review, feeder conductors are undersized because only
connected load was considered. What additional factor must be
evaluated?
A. Paint color
B. Demand load calculations
C. Building height only
D. Ceiling finish
Answer: B
