1. During an inspection of a newly installed branch circuit, an
inspector observes that the circuit conductors are properly sized,
but the equipment grounding conductor is missing. Which
conclusion is most appropriate?
A. The installation is acceptable because the circuit conductors are
correctly sized.
B. The installation is acceptable if the overcurrent device is a GFCI.
C. The installation has a grounding deficiency that must be evaluated
and corrected according to the applicable code provisions.
D. The installation is acceptable if the metal raceway is painted.
Answer: C. The installation has a grounding deficiency that must be
evaluated and corrected according to the applicable code provisions.
Rationale: An equipment grounding conductor provides a low-
impedance path for fault current so that an overcurrent protective
device can operate promptly during a fault. Properly sized circuit
conductors do not eliminate the need for an effective equipment
grounding path where one is required. An inspector should verify
whether the raceway itself is permitted as the grounding path or
whether a separate equipment grounding conductor is required.

,2. An inspector finds a receptacle installed in a location where
personnel could reasonably contact grounded surfaces while using
cord-connected equipment. What protection is generally most
important to evaluate?
A. Surge protection
B. Ground-fault circuit-interrupter protection
C. Arc-fault circuit-interrupter protection only
D. Overvoltage protection
Answer: B. Ground-fault circuit-interrupter protection
Rationale: GFCI protection is designed to interrupt a circuit when
leakage current indicates an imbalance between current flowing in
ungrounded and grounded conductors. It is particularly important in
locations where electrical equipment may be exposed to moisture or
where a person could provide a path to ground. The inspector must
determine whether the specific location and equipment fall within the
applicable GFCI requirements.
3. During a service inspection, the inspector notices that the
grounded conductor and equipment grounding conductors are
bonded together downstream of the service disconnecting means.
Why can this be hazardous?
A. It increases the normal operating voltage.
B. It can place objectionable current on equipment grounding paths and
metal enclosures.
C. It prevents the grounding electrode system from functioning.
D. It causes all circuit breakers to trip immediately.
Answer: B. It can place objectionable current on equipment
grounding paths and metal enclosures.

,Rationale: At the service or other specifically permitted bonding
location, the grounded conductor is bonded to the grounding and
bonding system. Downstream of the permitted bonding point, improper
neutral-to-ground connections can cause normal neutral current to
flow on equipment grounding conductors, raceways, and enclosures.
This can create shock hazards and other undesirable conditions.
4. An inspector is determining whether a panelboard has adequate
working space. Which factor is most important?
A. The color of the panelboard enclosure
B. The manufacturer's logo
C. The required depth, width, and clear working space around the
electrical equipment
D. Whether the panelboard is mounted above eye level
Answer: C. The required depth, width, and clear working space
around the electrical equipment
Rationale: Electrical equipment must generally have sufficient
dedicated working space to permit safe operation, inspection,
adjustment, servicing, and maintenance. The inspector should
evaluate the dimensions, accessibility, voltage, equipment
configuration, and surrounding conditions against the applicable code
requirements. Storage or obstructions within required working space
are significant safety concerns.
5. An inspector discovers combustible materials stored directly in
the required working space in front of a service panel. What should
the inspector do?
A. Ignore the condition because the panel is still energized.
B. Require the combustible materials to be removed from the required
3
, working space.
C. Require the panel to be painted red.
D. Replace every circuit breaker in the panel.
Answer: B. Require the combustible materials to be removed from
the required working space.
Rationale: Required electrical working space must remain accessible
and clear so qualified personnel can safely operate and service
electrical equipment. Combustible storage also increases the potential
severity of an electrical fault. The inspector should document the
obstruction and require correction in accordance with the adopted
requirements.
6. A circuit breaker repeatedly trips during normal operation. The
occupant asks the inspector to install a larger breaker so the circuit
will stop tripping. What is the correct inspection approach?
A. Recommend increasing the breaker size immediately.
B. Determine the cause of the overcurrent condition before changing the
protective device.
C. Remove the breaker entirely.
D. Replace the breaker with a fuse of any available rating.
Answer: B. Determine the cause of the overcurrent condition before
changing the protective device.
Rationale: Repeated tripping can indicate overload, short circuit,
ground fault, defective equipment, or another problem. Installing a
larger overcurrent device without verifying conductor ampacity and
circuit design can allow conductors to overheat and create a fire
hazard. The protective device must be appropriately matched to the
circuit and equipment.
