EXAM (ARKANSAS STATE ELECTRICAL
BOARD) ACTUAL PREP QUESTIONS AND WELL
REVISED ANSWERS - LATEST AND COMPLETE
UPDATE WITH VERIFIED SOLUTIONS –
ASSURES PASS
Course: Arkansas State Electrical Board Licensing – Journeyman Electrician Certification
Subject: National Electrical Code (NEC), Electrical Theory, Calculations, Wiring Methods,
Protection, Safety, and State-Specific Installation Standards
Description:
This comprehensive 200-question Arkansas Journeyman Electrician Exam is designed to mirror
the structure, difficulty, and technical depth of the official Arkansas State Electrical Board
examination. It integrates NEC-based code questions, electrical theory, conductor sizing,
raceway fill, transformer calculations, grounding and bonding, motors, overcurrent protection,
service calculations, and applied field scenarios. Both residential and commercial/industrial
installations are covered. Each multiple-choice question includes a correct answer followed by a
clear, instructional rationale in italics to reinforce learning and support exam readiness.
1. Which NEC article covers branch circuits?
A. Article 200
B. Article 210
C. Article 215
D. Article 220
Answer: B
Article 210 specifically governs branch circuits, including ratings, required
circuits, and installation rules.
2. The minimum burial depth for a 20A, 120V GFCI-protected UF cable
under residential property is:
A. 6 inches
B. 12 inches
C. 18 inches
D. 24 inches
,2|Page
Answer: C
NEC Table 300.5 lists 12 inches for GFCI-protected circuits under residential
driveways/walkways but 18 inches for general residential yards.

D. 240V
Answer: C
In a wye system, phase-to-phase voltage equals 120V × √3 ≈ 208V.
4. A 4 AWG copper conductor has what allowable ampacity (75°C terminal
rating)?
A. 60A
B. 85A
C. 95A
D. 100A
Answer: C
NEC Table 310.16 lists 4 AWG Cu at 85A (60°C), 95A (75°C), and 115A (90°C).
5. Which device is required to protect personnel against electric shock?
A. AFCI
B. GFCI
C. OCPD
D. Surge protector
Answer: B
Ground-fault circuit interrupters protect people by detecting ground-fault leakage
currents.

6. What is the minimum size copper grounding electrode conductor for a
200A service?
A. 6 AWG Cu
B. 4 AWG Cu
C. 2 AWG Cu
D. 1/0 AWG Cu
Answer: B
NEC 250.66 states that 4 AWG Cu is the minimum for services 200A.
7. The minimum working clearance in front of live electrical equipment
(≤600V) is:
A. 24 inches
B. 30 inches
C. 36 inches
D. 48 inches
Answer: C
NEC 110.26(A)(1) requires 3 ft minimum in Condition 1 environments.
8. A continuous load must be multiplied by what factor for conductor and
OCPD sizing?
A. 80%
B. 100%
C. 125%
D. 150%
Answer: C
NEC 210.20(A) and 215.3 require OCPDs and conductors at 125% of continuous
loads.
9. The grounding electrode for a building usually includes which of the
following?
, 4|Page
A. Gas pipe
B. Aluminum rod
C. Steel reinforcing bars
D. PVC water pipe
Answer: C
Rebar or UFER electrodes are permitted grounding electrodes; gas pipe is
prohibited.
10. What is the approximate resistance of the human body under dry
conditions?
A. 50Ω
B. 500Ω
C. 5,000Ω
D. 50,000Ω
Answer: C
Dry human skin can have resistance around 5,000Ω, but varies widely.
11. In a three-wire single-phase system, the neutral conductor carries:
A. The full load current
B. Half the load current
C. The difference in currents between the two hot legs
D. Zero current
Answer: C
Neutral carries unbalanced current.
12. Maximum number of 90° bends allowed in one conduit run:
A. 2
B. 3
C. 4
D. 5
Answer: C
NEC limits a raceway to 360° of bends total.
