HAWAII JOURNEYMAN ELECTRICIAN EXAM 2026 200 ACTUAL QUESTIONS &
VERIFIED ANSWERS WITH DETAILED EXPLANATIONS COMPLETE PRACTICE TEST
• This practice test mirrors the real Hawaii Journeyman Electrician Exam with 200
verified questions covering all NEC-based topics tested — use it by timing yourself,
marking uncertain answers, then reviewing the EXPERT RATIONALE for every
question you miss to reinforce weak areas before exam day.
• Each question features five answer choices (A–E), a clearly highlighted correct
answer, and a detailed EXPERT RATIONALE — making this the most complete self-
study tool available for the 2026 exam cycle.
1. What is the minimum cover requirement for a rigid metal conduit (RMC)
installed under a residential driveway?
A) 2 inches
B) 4 inches
C) 6 inches
D) 12 inches
E) 18 inches
CORRECT ANSWER: C) 6 inches
EXPERT RATIONALE: Per NEC Table 300.5, rigid metal conduit installed under a
residential driveway requires a minimum cover of 6 inches. This provides adequate
protection against the mechanical forces exerted by vehicle traffic over the conduit.
,2. According to the NEC, what is the maximum number of overcurrent devices
permitted in a panelboard?
A) 30
B) 36
C) 42
D) 48
E) 60
CORRECT ANSWER: C) 42
EXPERT RATIONALE: NEC 408.54 limits the number of overcurrent devices in a
panelboard to a maximum of 42. This applies to lighting and appliance branch-
circuit panelboards and is intended to prevent overloading of panel equipment.
3. What size copper conductor is required for a 200-ampere service entrance?
A) 2/0 AWG
B) 3/0 AWG
C) 4/0 AWG
D) 250 kcmil
E) 350 kcmil
CORRECT ANSWER: C) 4/0 AWG
EXPERT RATIONALE: Per NEC Table 310.12, the minimum copper conductor
size for a 200-ampere service is 4/0 AWG. This size ensures the conductor can
handle the full load without exceeding its ampacity rating.
4. A branch circuit that supplies only one utilization equipment is called a:
,A) General purpose branch circuit
B) Multiwire branch circuit
C) Individual branch circuit
D) Dedicated branch circuit
E) Appliance branch circuit
CORRECT ANSWER: C) Individual branch circuit
EXPERT RATIONALE: NEC Article 100 defines an individual branch circuit as one
that supplies only one piece of utilization equipment. This is different from a
general-purpose or appliance branch circuit, which may supply multiple outlets or
devices.
5. What is the minimum headroom required above electrical equipment rated
1200 amperes or more in a dedicated electrical space?
A) 5.5 feet
B) 6 feet
C) 6.5 feet
D) 7 feet
E) 8 feet
CORRECT ANSWER: C) 6.5 feet
EXPERT RATIONALE: NEC 110.26(A)(3) requires a minimum headroom of 6.5
feet (2.0 m) in front of electrical equipment rated 1200 amperes or more. This
ensures safe working clearance for electricians performing maintenance and
operation tasks.
6. What is the maximum voltage permitted between conductors for circuits
supplying luminaires in a dwelling unit?
, A) 120 volts
B) 150 volts
C) 240 volts
D) 277 volts
E) 480 volts
CORRECT ANSWER: A) 120 volts
EXPERT RATIONALE: NEC 410.73 restricts luminaire circuits in dwelling units to
a maximum of 120 volts between conductors. This is a safety measure to reduce
the risk of electric shock in residential environments where non-electrically trained
individuals are present.
7. Which of the following locations requires GFCI protection for 125-volt, 15-
and 20-ampere receptacles?
A) Living room
B) Bedroom
C) Garage
D) Dining room
E) Hallway
CORRECT ANSWER: C) Garage
EXPERT RATIONALE: Per NEC 210.8(A), GFCI protection is required for all 125-
volt, single-phase, 15- and 20-ampere receptacles in garages of dwelling units,
including attached garages. This is because garages are often damp environments
where the risk of ground faults is elevated.
8. The neutral conductor of a 3-phase, 4-wire wye system carries what type of
current?
