1. Under Arkansas electrical licensing rules, what is a key requirement for an
applicant seeking an electrical contractor's license?
A. The applicant must personally hold a journeyman license
B. The applicant must be a licensed master electrician or employ a licensed
master electrician
C. The applicant must employ two journeyman electricians
D. The applicant must hold a residential master license
Answer: The applicant must be a licensed master electrician or employ a
licensed master electrician
Rationale: Arkansas rules require an electrical contractor applicant to provide
proof that the applicant is a licensed master electrician or employs a licensed
master electrician.
2. If an Arkansas electrical contractor applicant is not personally the master
electrician, what additional documentation is required from the master
electrician?
A. A notarized apprenticeship certificate
B. A written estimate for the first project
C. An oath disclosing affiliations with other electrical contractors and verifying
,employment as superintendent or manager
D. A journeyman examination score
Answer: An oath disclosing affiliations with other electrical contractors and
verifying employment as superintendent or manager
Rationale: The Arkansas electrical contractor rule specifically addresses the
master electrician's affiliation with other contractors and requires verification of
the superintendent or manager role.
3. Which edition of the National Electrical Code is currently incorporated by
Arkansas electrical rules?
A. 2014 NEC
B. 2017 NEC
C. 2020 NEC
D. 2023 NEC
Answer: 2020 NEC
Rationale: Arkansas currently adopts the 2020 National Electrical Code as its
statewide electrical standard, subject to Arkansas-specific provisions and
exclusions.
4. What is the primary purpose of the Arkansas electrical code adoption?
A. To establish optional construction recommendations
B. To provide a uniform minimum standard for electrical construction,
installation, repair, and maintenance
C. To replace all local licensing requirements
D. To regulate only industrial electrical installations
Answer: To provide a uniform minimum standard for electrical construction,
installation, repair, and maintenance
Rationale: Arkansas rules establish the NEC as the statewide minimum electrical
standard and seek uniformity in electrical work throughout the state.
, 5. An electrical contractor is installing a 120/240-volt single-phase service.
Which conductor is normally identified as the grounded conductor?
A. Equipment grounding conductor
B. Grounding electrode conductor
C. Neutral conductor
D. Bonding jumper
Answer: Neutral conductor
Rationale: In a typical 120/240-volt single-phase system, the neutral is the
grounded conductor and provides the return path for line-to-neutral loads.
6. A service has a calculated load of 185 amperes. Which standard-size service
rating is generally appropriate when the calculated load does not exceed
the rating selected?
A. 150 A
B. 175 A
C. 200 A
D. 225 A
Answer: 200 A
Rationale: The service rating must be at least the calculated load. A 200-ampere
standard service rating is appropriate for a 185-ampere calculated load.
7. What is the primary function of the grounding electrode system at a
service?
A. To carry normal neutral current
B. To provide a reference to earth and facilitate fault/surge dissipation
C. To replace circuit breakers
D. To increase circuit voltage
Answer: To provide a reference to earth and facilitate fault/surge dissipation
, Rationale: The grounding electrode system connects the electrical system to
earth but is not intended to serve as the normal return path for load current.
8. A feeder supplies a 100-ampere panelboard. The feeder conductors are
protected by a 100-ampere breaker. What determines the minimum
ampacity of the conductors?
A. The panelboard's physical size
B. The feeder load calculation and applicable conductor ampacity rules
C. The number of circuits in the panel
D. The length of the panelboard
Answer: The feeder load calculation and applicable conductor ampacity rules
Rationale: Conductor selection is based on calculated load, allowable ampacity,
temperature limitations, adjustment/correction factors, termination ratings,
and other applicable NEC requirements.
9. What is the purpose of an overcurrent protective device?
A. To increase available fault current
B. To protect conductors and equipment from excessive current
C. To provide grounding electrode resistance
D. To regulate utility voltage
Answer: To protect conductors and equipment from excessive current
Rationale: Fuses and circuit breakers are primarily intended to protect
conductors and equipment against damaging overcurrent conditions.
10.A circuit contains continuous loads totaling 32 amperes. Ignoring other
applicable adjustments, what minimum branch-circuit ampacity is generally
required when the continuous load must be rated at 125%?
A. 32 A
B. 35 A
C. 40 A
D. 45 A
