How to use this guide
How to study Journeyman Electrician
Build each answer around code navigation and jobsite safety: identify the installation, find the applicable NEC article or table, verify conductor and overcurrent sizing, preserve grounding and bonding, and stop when equipment is not rated or protected.
1. Classify the installation
Identify the occupancy, equipment, circuit type, conductor material, load, and environmental condition.
2. Find the controlling NEC rule
Use the article, table, definition, exception, and notes before relying on memory.
3. Size and protect the circuit
Check load, ampacity, adjustment, correction, overcurrent protection, grounding, bonding, and equipment rating.
4. Verify safety before completion
Confirm working space, disconnects, labels, special-occupancy rules, and deenergized verification before the installation passes.
Definitions, Calculations, Theory and Plan Reading
Theory questions test NEC terms, electrical quantities, plan symbols, circuit relationships, reference navigation, and basic calculation setup.
Key rules
Rule 1
Definitions, Calculations, Theory and Plan Reading questions reward the answer that follows the official rule source, safety duty, and practical work sequence.
Exam cue: Identify the system, hazard, tool, code rule, or licensing duty being tested.
Rule 2
The strongest answer controls the hazard before continuing work, testing equipment, or documenting completion.
Exam cue: Check inspection, isolation, measurement, documentation, and environmental requirements.
Rule 3
Eliminate answers that ignore inspection, code clearance, environmental controls, lockout, labeling, or qualification limits.
Exam cue: Choose the safe compliant answer before the fastest production answer.
Common traps
Treating local, state, and federal rules as interchangeable.
Prevention: Avoid answers that skip inspection, ignore the code source, energize unsafe equipment, vent regulated material, or treat local rules as optional.
Skipping required inspection, isolation, documentation, or recovery steps.
Prevention: Avoid answers that skip inspection, ignore the code source, energize unsafe equipment, vent regulated material, or treat local rules as optional.
Choosing a convenient answer that exceeds the worker's qualification or equipment rating.
Prevention: Avoid answers that skip inspection, ignore the code source, energize unsafe equipment, vent regulated material, or treat local rules as optional.
Memory anchors
Defined Term
Use the NEC definition before relying on field slang or habit.
Voltage Current Resistance
Ohm's law connects voltage, current, and resistance in basic circuit calculations.
Power Formula
Watts relate to volts and amperes and help estimate load and circuit demand.
Plan Symbol
Plan symbols must be interpreted with the legend, specifications, and applicable code rule.
Copper Assumption
When an outline says otherwise is not noted, conductor calculations may assume copper.
Continuous Load
A continuous load is expected to run for three hours or more and can change sizing decisions.
Code Navigation
Find the article, table, exception, and notes before choosing a code answer.
Demand Factor
A demand factor reduces calculated load only when the NEC rule allows it.
Grounded Versus Grounding
Grounded conductors and equipment grounding conductors serve different purposes.
Plan Conflict
When a plan note conflicts with code minimums, the safer code-compliant requirement controls.

FAQ
Common Journeyman Electrician questions
What does the journeyman electrician exam cover?
It covers NEC definitions and theory, services, feeders, branch circuits, wiring methods, equipment, motors, controls, special occupancies, and renewable energy technologies.
Is this tied to one state?
The study map is weighted from the public Texas TDLR/PSI journeyman electrician outline, while the topic set is useful for many NEC-based state and local journeyman exams.
Is the exam open book?
TDLR states its electrician exams are open book. Texas uses the 2023 NEC through August 31, 2026 and changes to the 2026 NEC on September 1, 2026; candidates should verify the edition and book rules for their own test date and jurisdiction.
Is the Texas journeyman exam one 80-question test?
No. Since March 11, 2025, Texas has administered separate NEC Knowledge and Calculations portions. The current PSI bulletin lists 59 items for Knowledge and 26 for Calculations, including five non-scored items across the two portions. This site's 80-question mock is a combined study set, not a replica of one testing appointment.
Why are wiring methods and branch circuits so heavily weighted?
The public journeyman outline gives the most items to wiring methods/materials and branch-circuit calculations/conductors, so the 601-question bank follows that emphasis.
How should I use the 601 questions?
Start with NEC navigation and calculations, drill services and branch circuits, then use section drills for wiring methods, special occupancies, motors, controls, and renewables before 80-question mocks.
