Introduction
The Michigan Journeywoman/Journeyman Electrician
Exam is a rigorous assessment designed to evaluate a
candidate’s proficiency in the safe installation,
maintenance, and repair of electrical systems. This
,examination ensures that all licensed practitioners possess
the fundamental skills and technical knowledge required to
protect public health and safety. The assessment features a
comprehensive mix of multiple-choice questions and
complex scenario-based problems, reflecting the diverse
challenges encountered in the field. By focusing on real-
world application, regulatory compliance, and critical
decision-making, the exam verifies that candidates can
interpret the National Electrical Code and Michigan-
specific statutes effectively under professional conditions.
1. What is the maximum number of disconnects
permitted for a single service, grouped in one
location, as per NEC Article 230?
A. 2
B. 4
🟢 C. 6
D. 8
🔴 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 or in a group of separate enclosures.
2. In a residential kitchen, which of the following best
describes the requirement for small-appliance
branch circuits?
A. At least one 15-ampere circuit
🟢 B. At least two 20-ampere circuits
C. One 20-ampere circuit for the refrigerator only
D. Three 15-ampere circuits
🔴 Explanation: NEC 210.11(C)(1) requires at least two
20-ampere small-appliance branch circuits to feed all
receptacle outlets in the kitchen, pantry, and dining room.
3. When calculating the load for a commercial
building, what is the demand factor for the first
3,000 volt-amperes of general lighting load?
🟢 A. 100%
B. 50%
, C. 45%
D. 25%
🔴 Explanation: According to NEC Table 220.42, the
demand factor for general lighting in most commercial
occupancies (unlike dwelling units) is 100% for the total
volt-amperes.
4. A 240-volt single-phase motor draws 20 amperes.
What is the minimum size Copper THHN conductor
required for the branch circuit, assuming it is a
continuous load?
A. 14 AWG
B. 12 AWG
🟢 C. 10 AWG
D. 8 AWG
🔴 Explanation: Continuous loads must be sized at 125%
of the current. 20A x 1.25 = 25A. Per Table 310.16, 12
AWG Copper THHN is rated for 25A at 75°C, but 10 AWG
is often required for mechanical durability or per local
25A breaker sizing.
