PREP QUESTIONS AND WELL REVISED ANSWERS -
LATEST AND COMPLETE UPDATE WITH VERIFIED
SOLUTIONS – ASSURES PASS
Description:
This 200-question Master Electrician practice exam is tailored for the Arkansas
State Electrical Board licensing requirements. It integrates both theory and
applied field scenarios, covering NEC rules, load calculations, grounding &
bonding, conductor sizing, overcurrent protection, transformers, motors, services,
safety, and installation practices commonly assessed in Arkansas. Questions mirror
realistic exam difficulty, with clear rationales to reinforce understanding and help
ensure mastery of advanced electrical concepts required of a licensed Arkansas
Master Electrician.

B. Two
C. Three
D. None
Answer: B
NEC 210.11(C)(1) requires at least two 20A circuits for kitchen/dining
receptacles.
5. What is the maximum cord length for a range hood?
A. 2 ft
B. 3 ft
C. 4 ft
D. 6 ft
Answer: C
NEC 422.16(B)(4) limits range hood flexible cord to 4 feet.
6. A conductor is marked THHN. What does the “H” indicate?
A. Halogen-free
B. Heat-resistant
,3|Page
C. High-voltage
D. Hazard-rated
Answer: B
“H” indicates 75°C rating; “HH” indicates 90°C.
7. Which conductor must always be grounded in a service?
A. Any phase conductor
B. The equipment grounding conductor
C. The grounded (neutral) conductor
D. Any conductor over 150V
Answer: C
The system’s grounded conductor is bonded at service equipment.
8. What is the minimum burial depth for a direct-buried 120V cable under a
residential driveway?
A. 12 in
B. 18 in
C. 24 in
D. 6 in
Answer: C
NEC Table 300.5 requires 24 in under driveways.
9. What type of test ensures continuity of the grounding electrode conductor?
A. Insulation resistance test
B. Earth-resistance test
C. Polarity check
D. Megger test only
Answer: B
A ground resistance test evaluates connection and continuity to earth.

10. A 5 kW water heater at 240V draws how many amps?
A. 12.5A
B. 20.8A
C. 25A
D. 30A
Answer: C
I = 5000 ÷ 240 = 20.8A; continuous loads require 125%, rounding to 25A.
11. In a commercial kitchen, what type of wiring method is MOST commonly
required for durability?
A. NM cable
B. AC cable
C. Rigid metal conduit
D. Type MC cable
Answer: D
Commercial kitchens often require MC cable due to moisture and physical
protection needs.
12. Minimum spacing between receptacles in a dwelling living room?
A. 6 ft
B. 12 ft
C. 8 ft
D. 10 ft
Answer: B
No point along a wall can be more than 6 ft from a receptacle → 12 ft spacing.
13. What is the minimum size service conductor for a 150A dwelling service
(copper)?
A. 1 AWG
B. 2 AWG
C. 1/0 AWG
