1. During the inspection of a newly installed 120-volt, 20-ampere
branch circuit supplying receptacle outlets in a dwelling unit
family room, the inspector notices that the installer used 14 AWG
copper conductors protected by a 20-ampere circuit breaker. What
is the correct inspection outcome?
A. Approve because receptacles are rated 20 amperes
B. Approve if the conductors are less than 50 feet long
C. Reject because 14 AWG copper conductors cannot be protected
by a 20-ampere overcurrent device
D. Approve if AFCI protection is installed
Answer: C
Rationale: NEC 240.4(D) limits 14 AWG copper conductors to 15-
ampere overcurrent protection unless specifically permitted elsewhere
in the NEC. Installing a 20-ampere breaker on a 14 AWG branch
circuit creates an overcurrent hazard because the conductor may
overheat before the breaker trips.
2. While inspecting a dwelling service, the inspector finds that the
grounded (neutral) conductor and equipment grounding conductors
1
, are bonded together inside a downstream subpanel. What should
the inspector determine?
A. Accept because bonding improves fault current flow
B. Accept if the feeder is less than 100 feet
C. Accept if the subpanel contains six circuits or fewer
D. Reject because the grounded conductor must remain isolated
from equipment grounding conductors in subpanels
Answer: D
Rationale: NEC requires the grounded conductor to be bonded only at
the service disconnecting means. Downstream distribution panels must
keep neutrals isolated from equipment grounding conductors to
prevent objectionable current on metal parts.
3. A residential bathroom contains one 20-ampere branch circuit
supplying receptacles. The electrician also connected the bathroom
lighting in another bathroom to the same circuit. Is this compliant?
A. Yes, because lighting loads are small
B. No, because a bathroom receptacle circuit may only serve
receptacles unless it serves a single bathroom
C. Yes, if AFCI protected
D. Yes, if GFCI protected
Answer: B
Rationale: NEC 210.11(C)(3) requires at least one 20-ampere branch
circuit for bathroom receptacle outlets. That circuit may supply
receptacles in multiple bathrooms only, or all loads within one
bathroom.
2
, 4. An inspector measures the height of a service disconnect handle in
the highest position at 6 feet 11 inches above the floor. Is this
acceptable?
A. No
B. Yes
C. Only if readily accessible
D. Only in unfinished basements
Answer: B
Rationale: NEC 240.24(A) and 404.8(A) generally limit the maximum
height of operating handles to 6 feet 7 inches unless exceptions apply.
However, service disconnect handle limitations are generally governed
by 240.24, with accessibility considerations. Inspectors should verify
compliance with current NEC provisions and equipment listing.
5. Which receptacle in a dwelling kitchen requires GFCI protection?
A. Ceiling-mounted clock receptacle only
B. Refrigerator only
C. All receptacles serving countertop surfaces
D. Dishwasher only
Answer: C
Rationale: NEC 210.8(A) requires GFCI protection for receptacles
serving kitchen countertop surfaces. Modern NEC editions have
expanded GFCI requirements to additional kitchen appliances as well.

, 6. A detached garage is supplied by a feeder. Which grounding
requirement applies?
A. No grounding electrode required
B. Equipment grounding conductor only
C. A grounding electrode system is required if supplied by feeders
or branch circuits under applicable NEC provisions
D. Water pipe is sufficient
Answer: C
Rationale: Detached structures supplied by feeders or branch circuits
generally require grounding electrode systems according to NEC
Article 250 unless specific exceptions apply.
7. Which conductor is permitted to be re-identified as an ungrounded
conductor?
A. 14 AWG white conductor
B. 12 AWG gray conductor
C. A white conductor in a cable assembly used as a switch loop
where permitted
D. Equipment grounding conductor
Answer: C
Rationale: NEC permits re-identification of certain grounded
conductors used as ungrounded conductors in cable assemblies where
specifically allowed.
8. What is the primary purpose of AFCI protection?
