INTRODUCTION
The Wyoming Journeyman Electrician Exam is designed to verify the competency and
technical proficiency
of individuals seeking licensure within the state. This assessment ensures that
candidates possess
a deep understanding of the National Electrical Code (NEC), safety protocols, and
,theoretical
foundations required for safe electrical installations. The exam utilizes multiple-
choice and
scenario-based questions to evaluate critical thinking and real-world decision-
making. By focusing
on practical applications of electrical principles, regulatory compliance, and
professional ethics,
this examination serves as a rigorous benchmark for protecting public safety. Success
requires
demonstrating the ability to interpret complex code requirements and apply them to
various residential,
commercial, and industrial environments.
SECTION ONE: QUESTIONS 1–100
1. What is the maximum number of disconnects allowed at a single service location,
excluding the exceptions for fire pumps?
A. 2
B. 4
,🟢 C. 6
D. 8
🔴 Explanation: Per NEC 230.71, the service disconnecting means for each service
permitted by 230.2 shall consist of not more than six switches or six circuit breakers
mounted in a single enclosure or in a group of separate enclosures.
2. A 240-volt single-phase motor draws 30 Amperes. What is the minimum sized
copper THHN conductor required for the branch circuit?
A. 12 AWG
B. 10 AWG
🟢 C. 8 AWG
D. 6 AWG
🔴 Explanation: Conductors supplying a single motor must have an ampacity of not less
than 125% of the motor's full-load current rating (30A x 1.25 = 37.5A). Per Table 310.16, 8
AWG THHN copper is rated for 50A (correction factors notwithstanding).
3. Which of the following is the primary purpose of bonding electrical equipment?
A. To provide a path for lightning to ground
🟢 B. To establish electrical continuity and conductivity
, C. To prevent the flow of neutral current
D. To reduce the resistance of the earth
🔴 Explanation: Bonding is the permanent joining of metallic parts to form an electrically
conductive path that ensures electrical continuity and the capacity to conduct safely any
fault current likely to be imposed.
4. In a dwelling unit, a 15-ampere or 20-ampere receptacle outlet must be installed so
that no point measured horizontally along the floor line in any wall space is more
than how many feet from an outlet?
A. 3 feet
🟢 B. 6 feet
C. 10 feet
D. 12 feet
🔴 Explanation: NEC 210.52(A)(1) states that receptacles must be installed so that no
point measured horizontally along the floor line in any wall space is more than 6 feet from
an outlet.
5. What is the calculated load for a 12kW electric range in a single dwelling unit?
