1. During the inspection of a newly constructed one-family dwelling,
an inspector observes that Type NM cable passes through bored
holes in wood studs located 1 inch from the face of the framing
members. What is the most appropriate inspection outcome?
A. Approve because NM cable is permitted in wood framing regardless
of setback distance
B. Require steel nail plates or equivalent protection where the cable is
less than the minimum setback from the framing edge
C. Require the cable to be installed in conduit throughout the dwelling
D. Require AFCI protection instead of mechanical protection
Answer: B
Rationale: Type NM cable installed through framing members must
be protected from physical damage when the edge of the bored hole
is too close to the face of the framing member. Steel nail plates or
equivalent protection reduce the likelihood of nails or screws
damaging the cable during drywall installation.
2. A residential service disconnect enclosure contains the grounded
conductor bonded to the enclosure and equipment grounding
conductors terminated on the same bar. Under what condition is
this installation acceptable?
1
,A. Never
B. Only if the enclosure is outdoors
C. At the service disconnecting means where the main bonding jumper
is installed
D. Only in a detached garage
Answer: C
Rationale: The grounded (neutral) conductor is bonded to the
enclosure only at the service disconnecting means. Downstream
panelboards must keep grounded and equipment grounding
conductors isolated.
3. An inspector is evaluating a 200-amp dwelling service. The
grounding electrode conductor is connected only to a metal
underground water pipe. What additional consideration is
required?
A. Nothing further is required
B. The water pipe must be supplemented by another qualifying
grounding electrode unless exempted
C. Install another neutral conductor
D. Increase conductor size
Answer: B
Rationale: A metal underground water pipe serving as a grounding
electrode generally must be supplemented by another grounding
electrode because the continuity of the water pipe cannot always be
assured over time.
4. A receptacle installed on a kitchen countertop serves portable
appliances. Which protective device is generally required?
2
,A. AFCI only
B. GFCI only
C. GFCI protection regardless of appliance type
D. Surge protection only
Answer: C
Rationale: Kitchen countertop receptacles are required to have
GFCI protection because of the increased shock hazard associated
with portable appliances and proximity to water.
5. During a final inspection, a dishwasher is supplied by a branch
circuit with AFCI protection but no GFCI protection. The
dishwasher is permanently connected. What should the inspector
require?
A. AFCI only is sufficient
B. GFCI protection is required
C. Replace the dishwasher
D. Install a dedicated grounding electrode
Answer: B
Rationale: Modern residential installations require GFCI protection
for dishwashers because of the elevated shock risk associated with
water and grounded metal components.
6. A laundry area contains one 125-volt receptacle serving only the
washing machine. Which protection is required?
A. None
B. AFCI only
C. GFCI protection
D. Weather-resistant receptacle
3
, Answer: C
Rationale: Laundry area receptacles require GFCI protection to
minimize electrical shock hazards associated with moisture and
grounded equipment.
7. Which statement best describes the purpose of AFCI protection in
a dwelling?
A. Protects against overloads only
B. Detects dangerous arcing conditions that could start fires
C. Measures grounding resistance
D. Eliminates voltage drop
Answer: B
Rationale: Arc-Fault Circuit Interrupters are designed to detect
hazardous arcing conditions that conventional circuit breakers may
not recognize, thereby reducing the likelihood of electrical fires.
8. A receptacle is installed within 5 feet horizontally of a residential
bathtub. Which additional protection is typically required?
A. Tamper-resistant only
B. GFCI protection
C. Surge protection
D. Weatherproof cover
Answer: B
Rationale: Receptacles near bathtubs present increased shock
hazards and require GFCI protection to rapidly interrupt
dangerous fault currents.
