INTRODUCTION
This comprehensive examination is designed to rigorously assess the knowledge, skills, and professional
judgment required of an Alaska Electrical Administrator. The exam evaluates a candidate's mastery of
foundational electrical theory, the National Electrical Code (NEC) with state-specific amendments, and the
practical application of electrical standards. It features a combination of direct multiple-choice questions and
scenario-based problems that test real-world decision-making, problem-solving, and the ability to navigate
complex regulatory and safety requirements. The following questions emphasize critical thinking and ethical
,responsibility, ensuring candidates are prepared for the challenges of professional practice. This assessment is a
definitive tool for verifying competency and ensuring public safety.
SECTION ONE: QUESTIONS 1 – 100
1. What is the primary function of a surge arrester in an electrical power distribution system?
A. To protect equipment from lightning and switching surges by diverting current to ground.
B. To prevent overloads by opening the circuit under fault conditions.
C. To regulate voltage fluctuations by adjusting the transformer tap settings.
D. To store electrical energy for backup power during an outage.
🟢A
🔴 Explanation: Surge arresters are specifically designed to protect insulation and equipment from high-
voltage transient surges, such as those caused by lightning or switching, by providing a low-impedance path
to ground and limiting the voltage.
2. When calculating the minimum size for a service-entrance conductor for a continuous load, the National
Electrical Code (NEC) generally requires the conductor ampacity to be at least what percentage of the
continuous load?
A. 100%
B. 125%
C. 150%
D. 200%
,🟢B
🔴 Explanation: NEC Section 210.19(A)(1) requires that the ampacity of conductors supplying continuous
loads be at least 125% of the continuous load rating to account for heat generation and ensure safe
operation over extended periods.
3. In a grounded electrical system, the main bonding jumper is installed to create a connection between
which two points?
A. The grounded conductor (neutral) and the equipment grounding conductor at the service.
B. The phase conductors and the grounding electrode conductor.
C. The service-entrance conductors and the meter enclosure.
D. The generator and the transfer switch.
🟢A
🔴 Explanation: The main bonding jumper connects the grounded service conductor (neutral) to the
equipment grounding conductor and the service equipment enclosure, establishing the effective ground-
fault current path back to the source.
4. A job site has a 120/240-volt, single-phase, 3-wire service. What is the voltage between the two
ungrounded ("hot") conductors?
A. 0 V
B. 120 V
C. 208 V
D. 240 V
🟢D
🔴 Explanation: In a standard 120/240-volt single-phase system, the two ungrounded conductors are each
120 volts to ground (or neutral), but are 180 degrees out of phase, resulting in a potential difference of 240
volts between them.
, 5. When installing a non-metallic sheathed cable (NM) in a residential dwelling, what is the maximum
allowable distance from a box where the cable must be supported?
A. 6 inches
B. 8 inches
C. 12 inches
D. 18 inches
🟢C
🔴 Explanation: NEC Section 334.30 requires that non-metallic sheathed cable be supported and secured
within 12 inches of every outlet box, junction box, cabinet, or fitting.
6. Under the NEC, what is the minimum allowed size for a copper equipment grounding conductor for a 100-
ampere branch circuit?
A. #14 AWG
B. #12 AWG
C. #10 AWG
D. #8 AWG
🟢D
🔴 Explanation: Based on NEC Table 250.122, the minimum size copper equipment grounding conductor for
a circuit protected by a 100-amp overcurrent device is #8 AWG.
7. Which of the following describes the function of a Type GFCI (Ground-Fault Circuit-Interrupter) receptacle?
A. It protects against phase-to-phase short circuits.
B. It protects against overloads by melting a fusible element.
C. It monitors the current imbalance between the hot and neutral conductors and opens the circuit if a
ground fault is detected.
D. It suppresses voltage transients to protect sensitive electronic equipment.
