Colorado Journeyman Wireman (6 plus Year Apprentice Exam) Book Package

Prepare for the Colorado Journeyman Wireman 6 Plus Year Apprentice Exam with a focused electrical code book package built around the code edition used for Colorado electrical examinations. This package includes the National Electrical Code, NEC, 2026 Edition, giving candidates the primary code resource needed to study electrical requirements, locate important NEC provisions, practice code navigation, and prepare for the types of questions found on the Colorado Journeyman Wireman examination.

Effective August 1, 2026, Colorado electrical examination questions are based on the 2026 National Electrical Code. The 6 Plus Year Apprentice Exam follows the Journeyman Wireman examination content and evaluates knowledge across general electrical principles, services, feeders, branch circuits, grounding and bonding, overcurrent protection, conductors, raceways, special occupancies, motors, transformers, photovoltaics, and electrical calculations.

The 6 Plus Year Apprentice Exam is connected to Colorado requirements for apprentices who have remained registered for six or more years. Colorado law requires certain long-term registered apprentices to take the Journeyman Wireman examination periodically until they receive a passing score or otherwise satisfy applicable requirements. Passing the examination alone does not automatically result in a journeyman license; applicants must also meet the experience and other licensing qualifications established by the Colorado State Electrical Board.

Learning how to use the NEC efficiently is an important part of preparation. Electrical licensing exams test more than memorization. Candidates need to understand electrical principles, recognize which code rules apply to a situation, perform calculations, and navigate the NEC efficiently enough to locate applicable requirements within the examination time.

What You Get

Open Book Test

The Colorado electrical examination allows use of an examination reference provided at the testing center. Effective August 1, 2026, PSI provides the 2026 National Electrical Code and a formula page for the examination.

The testing-center reference cannot be written in, highlighted, underlined, or indexed, and candidates may not use other materials. Because the examination copy is supplied at the test center, candidates should prepare with a clean-code navigation strategy rather than depending on personal notes, handwritten markings, or custom indexing.

This makes familiarity with the NEC especially important. Candidates should know how the code is organized and become comfortable locating definitions, general installation rules, wiring methods, conductor requirements, grounding and bonding provisions, motor requirements, special occupancies, special equipment, and calculation-related tables.

During study sessions, practice finding answers directly in the 2026 NEC without depending on extensive notes. Start by identifying the subject of a question, determine which NEC article or chapter applies, and then narrow the search to the appropriate section, table, exception, or definition. Repeated navigation practice can reduce the time spent searching during the actual exam.

Licensing Steps

Colorado Journeyman Wireman licensing is regulated through the Colorado State Electrical Board within the Division of Professions and Occupations. The licensing process combines qualifying electrical experience with examination requirements.

  1. Maintain the required apprentice registration. Colorado electrical apprentices are registered with the State Electrical Board while accumulating qualifying experience.
  2. Accumulate qualifying electrical experience. Journeyman electrician applicants must document the practical experience required by Colorado law.
  3. Complete required training. Colorado journeyman licensing requirements include training in electrical safety, the National Electrical Code and its applications, and other training required by the State Electrical Board.
  4. Take the required Journeyman Wireman examination. Apprentices who have been registered for at least six years are subject to Colorado's examination requirements for long-term apprentices.
  5. Prepare using the current examination code edition. For exams effective August 1, 2026, candidates should study the 2026 National Electrical Code.
  6. Complete the PSI examination. The 6 Plus Year Apprentice Exam includes 90 scored questions with up to 10 additional non-scored questions.
  7. Meet all journeyman licensing qualifications. Passing the examination does not replace experience, training, or other requirements established by the Colorado State Electrical Board.
  8. Apply for licensure when qualified. Candidates who satisfy the applicable examination and experience requirements complete the Colorado licensing process through the Division of Professions and Occupations.

State Requirements

Colorado requires a Journeyman Electrician applicant to provide evidence of at least 8,000 hours of qualifying apprenticeship or practical electrical experience accumulated over a period of at least four years. The qualifying experience involves wiring for, installing, and repairing electrical apparatus and equipment for electric light, heat, and power.

Colorado also requires a portion of that experience to be in commercial, industrial, or substantially similar electrical work. Current law requires 2,000 hours accumulated over at least two years of the qualifying experience to fall within that category.

The 6 Plus Year Apprentice examination requirement addresses apprentices who remain registered for an extended period. A registered apprentice who has reached at least six years of registration may be required to take the Journeyman Wireman examination at intervals established by Colorado law until the apprentice receives a passing result or qualifies for an applicable exemption.

An apprentice who has been registered for at least six years but has not yet met all Journeyman Electrician licensing qualifications may still be required to take the examination. Passing the 6 Plus Year Apprentice Exam does not by itself grant a Journeyman Electrician license. The apprentice must satisfy all applicable experience, training, and licensing requirements before the State Electrical Board may issue the license.

For candidates who already have substantial field experience, examination preparation provides an opportunity to connect practical electrical work with formal NEC requirements. Experienced apprentices may recognize equipment and installation methods from the field but still need targeted practice locating the exact code rules that govern those installations.

Reference Books

  • National Electrical Code, NEC, 2026 Edition
    The 2026 NEC establishes electrical installation requirements covering areas such as wiring and protection, wiring methods and materials, equipment for general use, special occupancies, special equipment, special conditions, communications systems, grounding and bonding, conductor sizing, services, feeders, branch circuits, motors, transformers, photovoltaic systems, and related electrical safety requirements. Colorado electrical examination questions are based on the 2026 NEC effective August 1, 2026.

The NEC is most useful when candidates learn both the technical rules and the structure of the code. Knowing that an answer exists somewhere in the NEC is not enough when examination time is limited. Candidates should practice moving from a question to the relevant article, section, table, or definition as efficiently as possible.

Pay particular attention to cross-references. Many electrical questions cannot be answered by reading only one sentence. A code section may direct you to another article, table, exception, or condition. Understanding those relationships is an important part of successful NEC navigation.

Test Information and Study Materials

General Electrical Knowledge: Review basic electrical concepts, code definitions, installation requirements, and the principles that support safe electrical work. Electrical theory and common formulas remain important because calculation problems may require candidates to apply them rather than simply look up an answer.

Services, Feeders, and Branch Circuits: Study service requirements, feeder sizing, branch-circuit rules, load considerations, disconnecting means, and related protection requirements. Practice distinguishing between service, feeder, and branch-circuit rules so you know where to begin searching.

Grounding and Bonding: With 14 scored questions, grounding and bonding is the largest individual area on the examination. Review grounding electrode systems, equipment grounding conductors, bonding requirements, conductor sizing, separately derived systems, and other applicable NEC provisions.

Overcurrent Protection: Study overcurrent protective devices, conductor protection, standard ratings, permitted applications, and requirements affecting circuit breakers and fuses.

Conductors and Cables: Practice conductor ampacity, insulation types, temperature limitations, adjustment and correction factors, conductor identification, and cable installation requirements. Learn how to locate and apply NEC ampacity tables efficiently.

Raceways and Boxes: Review raceway requirements, conductor fill, box fill, installation rules, permitted uses, and associated fittings. Calculation practice can be helpful in this area because some problems require several steps.

Special Occupancies and Special Equipment: Become familiar with where the NEC addresses locations and equipment subject to additional requirements. These questions reward candidates who understand the code's organization and can quickly recognize which article applies.

Motors and Transformers: Review motor circuit conductors, overload protection, short-circuit and ground-fault protection, disconnecting means, transformer requirements, and the calculations commonly associated with this equipment.

Photovoltaics: The Journeyman Wireman outline includes photovoltaic questions. Candidates should review applicable NEC provisions for photovoltaic systems and understand where those requirements are located.

Electrical Calculations: The examination includes nine scored electrical calculation questions. Candidates should practice calculations using electrical theory, common formulas, NEC tables, and code requirements. PSI also advises candidates to review electrical theory and common formulas as part of preparation.

A productive study method is to combine content review with timed code searches. Choose a topic from the examination outline, answer several practice questions, and track how long it takes to locate the controlling NEC rule. Then review why the answer is correct and identify any related exceptions or conditions. This creates both technical understanding and navigation speed.

How 1 Exam Prep Helps You Reach Your Goal

1 Exam Prep helps candidates approach the Colorado Journeyman Wireman 6 Plus Year Apprentice Exam with an organized, trade-focused study structure. The examination covers a wide range of electrical topics, and structured preparation can help candidates spend their study time on the subjects that actually appear on the published outline.

The 2026 National Electrical Code provides the foundation for preparation after Colorado's August 1, 2026 code transition. Working regularly with the same NEC edition used as the basis for examination questions helps candidates become familiar with terminology, article organization, tables, cross-references, and electrical requirements.

1 Exam Prep emphasizes practical code navigation. Instead of trying to memorize the entire NEC, candidates can learn how to recognize the subject of a question, identify the likely article, and move efficiently to the controlling section or table. This approach is especially useful because the NEC provided at the testing center cannot contain personal highlighting, handwritten notes, underlining, or indexing.

Practice-oriented preparation can also help candidates strengthen weaker areas such as grounding and bonding, conductor calculations, motors, transformers, raceway fill, services, and feeder calculations. A consistent study routine that combines NEC navigation, electrical theory, calculations, and examination-style questions can help build confidence before test day.

For experienced apprentices, preparation also helps connect years of field knowledge with the precise code language used in licensing examinations. Knowing how an installation is commonly performed in the field is valuable, but the examination requires candidates to identify the code-compliant answer under the conditions presented in the question.
