This practice assessment is designed to prepare candidates for the Texas Journeyman
Electrician Exam by simulating the rigorous testing environment. The purpose of this
exam is to ensure that candidates possess the necessary skills and technical knowledge
to perform electrical work safely and in compliance with the National Electrical Code
and Texas state regulations. The assessment covers foundational theory, scenario-based
problem solving, and real-world application. Through a mix of multiple-choice questions,
candidates are evaluated on their ability to make critical decisions regarding safety,
ethics, and regulatory compliance, ensuring they are ready for the responsibilities of a
licensed journeyman.
1. What is the maximum distance that a manual pull station can be located from
the exit doorway of a building?
,A. 3 feet
B. 5 feet
C. 10 feet
D. 15 feet
🟢 B. 5 feet
🔴 RATIONALE: Per standard fire alarm signaling codes and general safety
accessibility, manual pull stations must be located within 5 feet of the exit doorway
opening to ensure visibility and ease of access during an emergency.
2. A 240-volt, single-phase heater has a resistance of 12 ohms. What is the current
flow in the circuit?
A. 10 amperes
B. 15 amperes
C. 20 amperes
D. 24 amperes
🟢 C. 20 amperes
🔴 RATIONALE: Using Ohm's Law (I = E / R), 240 volts divided by 12 ohms equals 20
amperes.
3. Which of the following is the minimum size copper grounding electrode
conductor for a service with 2/0 AWG copper ungrounded service-entrance
conductors?
A. 8 AWG
B. 6 AWG
,C. 4 AWG
D. 2 AWG
🟢 C. 4 AWG
🔴 RATIONALE: According to NEC Table 250.66, for 2/0 AWG copper ungrounded
service conductors, the minimum size for a copper grounding electrode conductor is 4
AWG.
4. In a commercial garage, any area located below the floor level is classified as:
A. Class I, Division 1
B. Class I, Division 2
C. Class II, Division 1
D. Non-hazardous
🟢 A. Class I, Division 1
🔴 RATIONALE: Because heavier-than-air vapors can settle in low spots, the NEC
classifies pits or areas below floor level in commercial garages as Class I, Division 1
hazardous locations.
5. What is the minimum clear working space depth for electrical equipment
operating at 480 volts to ground where there are exposed live parts on one side
and a grounded surface on the other (Condition 2)?
A. 3 feet
B. 3.5 feet
C. 4 feet
D. 5 feet
, 🟢 B. 3.5 feet
🔴 RATIONALE: NEC Table 110.26(A)(1) specifies that for voltages between 151-600V
to ground, Condition 2 requires a minimum clear distance of 3.5 feet.
6. Under the Texas Electrical Safety and Licensing Act, who is responsible for
ensuring an electrical apprentice works under the supervision of a licensed
electrician?
A. The apprentice
B. The building owner
C. The master electrician or electrical contractor
D. The local building inspector
🟢 C. The master electrician or electrical contractor
🔴 RATIONALE: Texas administrative rules place the burden of supervision and
compliance on the master electrician of record or the licensed electrical contractor.
7. Which of the following conductor types is specifically rated for use in wet
locations?
A. THHN
B. THW
C. TW
D. Both B and C
🟢 D. Both B and C
🔴 RATIONALE: Conductors with a "W" in their designation (like THW or TW) are rated
for wet locations. THHN is rated for dry and damp locations only.
