1. During an inspection of a newly installed commercial service, the
inspector observes that the service disconnect is not readily
accessible because it is located in a locked electrical room that
only maintenance personnel can access. According to the NEC,
what is the primary concern?
A. The disconnect is acceptable if the owner has a master key.
B. The disconnect location violates accessibility requirements because
emergency access is restricted.
C. The disconnect is acceptable if labeled.
D. The disconnect is acceptable if remote operation is provided.
Answer: B
Rationale: Readily accessible means capable of being reached quickly
without requiring tools, climbing, or special permissions. Service
disconnecting means must be readily accessible to qualified personnel
and emergency responders where applicable. Restricted access can
delay emergency disconnect operations and is generally inconsistent
with NEC intent.
2. An inspector reviews feeder conductors installed in parallel. Which
condition must be verified to comply with NEC requirements?
1
,A. Conductors may differ in length by up to 20%.
B. Conductors may be different materials if ampacity is equal.
C. Conductors must have identical conductor material, insulation type,
length, and termination characteristics.
D. Conductors only need identical ampacity.
Answer: C
Rationale: Parallel conductors must share current equally. NEC
requires conductors in parallel to have the same length, conductor
material, insulation characteristics, size, and termination method to
prevent unequal current distribution and overheating.
3. During a hospital inspection, the electrical inspector notices
emergency system wiring sharing a raceway with normal branch
circuits. What is the proper determination?
A. Acceptable if conductors have equal insulation ratings.
B. Acceptable if raceway fill does not exceed limits.
C. Not permitted except where specifically allowed by NEC.
D. Always acceptable in healthcare occupancies.
Answer: C
Rationale: Emergency system wiring generally must remain
independent from normal wiring to ensure reliability during
emergencies. Only specific NEC exceptions allow common raceways.
4. A transformer supplying a separately derived system has the
system bonding jumper installed at both the transformer and
downstream disconnect. What is the inspection outcome?
A. Correct because redundancy improves safety.
B. Acceptable if grounding electrode conductors are identical.
2
,C. Incorrect because multiple bonding locations create parallel neutral
current paths.
D. Acceptable for transformers over 500 kVA.
Answer: C
Rationale: Only one effective bonding point is permitted for separately
derived systems. Multiple bonding locations create objectionable
current on equipment grounding conductors and metal raceways.
5. An inspector evaluates GFCI protection for kitchen receptacles in a
commercial establishment. Which statement is correct?
A. Only receptacles within 3 feet of sinks require GFCI protection.
B. All receptacles require GFCI.
C. GFCI requirements depend on NEC occupancy and equipment
provisions.
D. GFCI protection is optional if AFCI protection is installed.
Answer: C
Rationale: Commercial kitchen GFCI requirements vary according to
equipment type, voltage, location, and occupancy. Inspectors must
apply the appropriate NEC section rather than a single generalized
rule.
6. During an industrial inspection, a raceway enters a cabinet without
an approved fitting. What hazard exists?
A. Increased conductor resistance.
B. Reduced grounding impedance.
C. Mechanical damage to conductor insulation and inadequate bonding
continuity.
D. Increased conductor ampacity.
3
, Answer: C
Rationale: Approved fittings protect conductor insulation from
abrasion and maintain electrical continuity of metallic raceways.
Missing fittings compromise both mechanical and electrical integrity.
7. Which inspection principle best supports consistent code
enforcement?
A. Personal preference.
B. Local custom.
C. Uniform application of adopted codes based on documented
evidence.
D. Contractor experience.
Answer: C
Rationale: Electrical inspectors enforce adopted codes consistently
using objective observations, documented violations, and accepted
code interpretations rather than personal judgment.
8. What is the primary purpose of equipment grounding conductors?
A. Carry normal neutral current.
B. Stabilize voltage.
C. Provide an effective ground-fault current path facilitating operation of
overcurrent devices.
D. Reduce harmonic distortion.
Answer: C
Rationale: Equipment grounding conductors provide a low-impedance
fault return path, enabling protective devices to clear faults rapidly
and minimize shock hazards.
