Introduction
The Arkansas Master Electrician Exam is designed to
verify the advanced technical knowledge and
administrative capabilities required for licensing at the
master level. This comprehensive assessment ensures
,that candidates possess the expertise to design, install,
and oversee complex electrical systems while
maintaining strict adherence to safety standards and
legal mandates. The exam evaluates a broad spectrum
of skills, including intricate load calculations, grounding
system design, and the interpretation of regulatory
codes. Through a series of multiple-choice and scenario-
based questions, the assessment emphasizes real-world
application, critical decision-making, and the ethical
responsibility of ensuring public safety through
professional electrical practice.
SECTION ONE: QUESTIONS 1–100
1. What is the maximum number of disconnects
permitted for a single service, grouped in one
location, as per NEC requirements?
A. 2
B. 4
C. 6
D. 8
,🟢 Correct answer C. 6
🔴 Explanation: NEC 230.71(A) states that the service
disconnecting means for each service shall consist of
not more than six switches or six circuit breakers
mounted in a single enclosure, in a group of separate
enclosures, or in or on a switchboard.
2. A 240-volt, single-phase motor draws 30 amperes.
What is the minimum size Copper THHN conductor
required for the branch circuit, assuming a 125%
multiplier for continuous duty?
A. 10 AWG
B. 8 AWG
C. 6 AWG
D. 4 AWG
🟢 Correct answer B. 8 AWG
🔴 Explanation: 30A x 1.25 = 37.5A. According to Table
310.16, 10 AWG THHN is rated for 30A (small conductor
rule) or 35A generally, but 8 AWG is required to safely
, carry 37.5A at the 75°C column typically used for
terminations.
3. In Arkansas, a Master Electrician is responsible for
which of the following regarding permit
applications?
A. Only providing the license number to the apprentice
B. Ensuring all work is performed by a licensed
professional or registered apprentice
C. Signing off on work they did not personally supervise
D. Maintaining a 1:5 ratio of journeymen to apprentices
🟢 Correct answer B. Ensuring all work is performed by
a licensed professional or registered apprentice
🔴 Explanation: Under Arkansas State Board of
Electrical Examiners rules, the Master Electrician of
record is responsible for the overall supervision and
ensuring that all individuals performing electrical work
are properly licensed or registered.
