This assessment evaluates the foundational knowledge and practical understanding required
of individuals seeking registration as apprentice electricians in Texas. The examination
focuses on safe work practices, basic electrical theory, National Electrical Code (NEC)
familiarity, tool usage, and installation principles. Candidates are expected to demonstrate
comprehension of electrical systems, conductors, circuits, grounding, and workplace safety.
The purpose of this exam is to ensure that apprentices can work under supervision while
adhering to industry standards and safety regulations applicable within the electrical trade.
Core Competency Areas:
Electrical Safety and OSHA Standards
Basic Electrical Theory
, NEC Code Familiarity
Wiring Methods and Materials
Tools and Equipment Usage
Grounding and Bonding
Circuit Installation Principles
Candidate Instructions: This examination consists of approximately 80 multiple-choice
questions. You are required to answer all questions. Select the best answer for each question.
The time allocated for this examination is 2.5 hours. Calculators are permitted unless
otherwise stated. Read each question carefully before selecting your answer. Mark only one
answer per question. Ensure all responses are recorded clearly. No reference materials are
allowed unless explicitly authorized.

Q1. A worker is preparing to install conduit in a commercial building. Before beginning,
they must ensure compliance with safety standards. Which action is MOST appropriate
prior to starting work?
A. Begin installation immediately to save time
B. Verify the circuit is energized for testing
,C. Lockout/tagout the electrical source
D. Use insulated gloves only
Correct Answer: 🔵 C. Lockout/tagout the electrical source
Explanation: 🟢 Lockout/tagout ensures circuits are de-energized, preventing accidental
energization. A is unsafe, B is dangerous, and D alone does not eliminate electrical
hazards.
Q2. What is the primary function of a circuit breaker in an electrical system?
A. Increase voltage
B. Store energy
C. Protect against overcurrent
D. Reduce resistance
Correct Answer: 🔵 C. Protect against overcurrent
Explanation: 🟢 Circuit breakers interrupt excessive current flow. A and D are unrelated,
and B refers to capacitors, not breakers.
Q3. Which unit measures electrical resistance?
A. Volt
B. Ampere
, C. Ohm
D. Watt
Correct Answer: 🔵 C. Ohm
Explanation: 🟢 Resistance is measured in ohms. Volts measure voltage, amperes measure
current, and watts measure power.
Q4. A 120V circuit supplies a device drawing 10 amps. What is the power consumption?
A. 12 watts
B. 120 watts
C. 1,200 watts
D. 12,000 watts
Correct Answer: 🔵 C. 1,200 watts
Explanation: 🟢 Power = Voltage × Current = 120 × 10 = 1200W. Other values are
incorrect calculations.
Q5. Which color wire is typically used for grounding in residential wiring?
A. Black
B. White
C. Green
D. Red
