Introduction
The Texas Journeyman Electrician Exam is designed to
evaluate the competency and technical proficiency of
individuals seeking licensure within the state. This
assessment ensures that candidates possess the requisite
,knowledge of the National Electrical Code and state-
specific amendments necessary to perform electrical
installations safely and effectively. The exam encompasses
a broad spectrum of topics, ranging from fundamental
theory and complex calculations to regulatory compliance
and safety protocols. Through a combination of multiple-
choice questions and scenario-based problems, the exam
emphasizes real-world application, critical thinking, and
professional decision-making. Mastery of these concepts is
essential for maintaining public safety and ensuring the
integrity of electrical systems in residential, commercial,
and industrial environments.
SECTION ONE: QUESTIONS 1–100
1. What is the maximum number of disconnects
allowed for a single service, provided they are
grouped in one location?
A. 2
B. 4
,C. 6
D. 8
🟢 C. 6
🔴 Explanation: According to NEC Article 230.71, 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. A 240-volt, single-phase circuit has a total
resistance of 12 ohms. What is the current flowing
through the circuit?
A. 10 amperes
B. 20 amperes
C. 24 amperes
D. 30 amperes
🟢 B. 20 amperes
🔴 Explanation: Using Ohm's Law (I = V /R), dividing
240 volts by 12 ohms results in 20 amperes of current.
