Exam Details

The Colorado Journeyman Wireman examination is administered through PSI for the Colorado State Electrical Board. The exam is computer-based and is designed to measure entry-level competence in the job task areas where a Colorado journeyman electrician is legally allowed to practice. Passing the examination is part of the licensing process, and applicants must also meet Colorado’s minimum qualifications for licensure.

The Colorado Journeyman Wireman examination is listed with 90 scored items, 240 minutes of testing time, and a required score of 70%, which equals 63 correct scored items. The exam may also include up to 10 non-scored items with an additional 30 minutes. Non-scored items are used for examination development and do not count toward the final score.

The Journeyman Wireman content outline includes general electrical knowledge, services, feeders and branch circuits, grounding and bonding, overcurrent protection, conductors and cables, raceways and boxes, special occupancies, special equipment, electrical devices, motors, transformers, photovoltaics, and electrical calculations. These subjects cover both practical electrical work and code-based knowledge, making a balanced study plan important.

The listed exam content includes 11 questions on general electrical knowledge, 9 questions on services, feeders, and branch circuits, 14 questions on grounding and bonding, 6 questions on overcurrent protection, 8 questions on conductors and cables, 5 questions on raceways and boxes, 5 questions on special occupancies, 6 questions on special equipment, 5 questions on electrical devices, 6 questions on motors, 4 questions on transformers, 2 questions on photovoltaics, and 9 questions on electrical calculations.

This range of exam topics shows why preparation should include more than reading code sections at random. A candidate may need to interpret a grounding rule, identify a service requirement, work a calculation, understand a motor installation, apply an overcurrent protection rule, or locate the proper code section for a special occupancy. The strongest preparation plans combine trade review, NEC navigation, and repeated practice with electrical calculations.

Open Book Test

The Colorado Journeyman Wireman examination is a reference-based, open book exam. The PSI bulletin states that all examination questions are consistent with the National Electrical Code book and that the NEC code book and formula page are provided at the test center. Effective August 1, 2026, Colorado examination questions are listed as consistent with the 2026 National Electrical Code, with the 2026 NEC code book and formula page provided at the test center.

Open book testing does not mean the exam is easy. Candidates may not rely on the ability to look up every answer slowly. The exam is timed, and candidates need to understand how to identify the subject of a question, move through the code book efficiently, and apply the correct rule. Strong preparation includes regular practice with the NEC’s structure, article layout, definitions, tables, notes, and index.

The National Electrical Code 2026 Paperback included in this combo gives students a physical reference for building code navigation skills before exam day. During study, students can practice locating common journeyman exam subjects such as services, feeders, branch circuits, grounding electrode systems, bonding, equipment grounding conductors, conductor ampacity, raceways, boxes, motors, transformers, overcurrent protection, special occupancies, and electrical calculations.

Because Colorado’s exam reference materials are controlled by the testing center, candidates should follow PSI’s current exam-day rules for allowed materials, references, identification, security procedures, calculators, and testing conduct. The code book and formula page provided during testing should be used according to the testing instructions.

Licensing Steps

Colorado journeyman electrician candidates begin by meeting the experience and education requirements established by the Colorado State Electrical Board. Applicants must document qualifying electrical experience and classroom education before pursuing licensure. The experience must be earned over the required time period and documented according to the Board’s application requirements.

After meeting the required qualifications, the applicant completes the licensing process through the Colorado Division of Professions and Occupations. The applicant must submit the required application materials and documentation. The Board reviews the applicant’s qualifications as part of the licensing process.

PSI administers the examination program for Colorado electrical licensing. Candidates schedule and take the examination through PSI according to the testing procedures. The examination is administered by computer, and candidates receive score information after completing the exam.

After passing the examination, the applicant must file the license application with the Colorado Division of Professions and Occupations. Passing the exam by itself does not automatically guarantee licensure. The applicant must still demonstrate that the minimum qualifications for licensure are satisfied under Colorado law.

A strong licensing plan should begin before the exam date. Candidates should organize work history documentation, classroom education records, and application materials early. Study should also begin early enough to cover major trade topics, calculations, and NEC navigation. Waiting until the exam is scheduled can make preparation feel rushed, especially for candidates who need additional practice with calculations or code lookup.

State Requirements

Colorado Journeyman Electrician applicants must document 8,000 hours of experience earned in no less than 4 years. Of those hours, 2,000 hours must be in commercial or industrial work. The experience requirement is intended to show that the applicant has developed practical electrical construction wiring knowledge under appropriate supervision.

Colorado also requires 288 hours of classroom education for all journeyman electrician applicants. The education must be documented with a transcript or similar statement. Classroom education supports the technical side of electrical training, including safety, electrical theory, code knowledge, and related trade instruction.

Apprentices and other workers moving toward journeyman licensure should keep accurate records of employment, supervised work, and education. Proper documentation is important because the Board must be able to review and verify the applicant’s qualifications. Applicants should use the forms and application process required by the Colorado Division of Professions and Occupations.

Colorado also provides licensing by endorsement and reciprocity options under specific conditions. For journeyman reciprocity, Colorado participates in the National Electrical Reciprocal Alliance with certain states. Applicants using endorsement or reciprocity must satisfy the applicable Colorado requirements for current licensing, examination history, good standing, and documentation.

The Colorado journeyman electrician license is separate from electrical contractor registration. To perform electrical contracting in Colorado, an electrical contractor must be registered with the state and must hold or employ a licensed master electrician to serve as the responsible individual for the company.

Test Information and Study Materials

Colorado Journeyman Wireman preparation should include a broad review of technical electrical topics and code-based installation requirements. Important study areas include general electrical knowledge, services, feeders, branch circuits, grounding and bonding, overcurrent protection, conductors, cables, raceways, boxes, special occupancies, special equipment, electrical devices, motors, transformers, photovoltaics, and electrical calculations.

The 2026 Colorado Journeyman Electrician Study Guide helps students organize these topics into a focused study path. Instead of studying scattered code sections without a plan, students can review one major subject at a time and connect that subject to practical field work. This helps candidates understand not only where a rule is located, but also how that rule applies to real electrical installations.

The 2026 Electrician Calculations Study Guide supports the math portion of preparation. Colorado’s exam outline includes electrical calculations, and the PSI bulletin advises review of electrical theory and common formulas. Students should be able to use basic electrical theory formulas because that knowledge may be required to work problems in the calculations portion of the examination.

Useful calculation study areas include Ohm’s law, power formulas, voltage drop concepts, conductor sizing, box fill, raceway fill, load calculations, service and feeder calculations, motor calculations, transformer calculations, overcurrent protection, and photovoltaic-related calculations. A student should practice writing formulas, identifying known values, converting units where needed, and checking whether the final answer makes practical sense.

Calculation preparation should be active. Reading a solved example may help introduce a concept, but repeated practice builds speed and accuracy. Timed practice is especially useful because a candidate may need to solve math-based questions while also managing code lookup and pacing across the full exam.

The National Electrical Code 2026 Paperback should be used throughout the study process. Students should practice locating definitions, article sections, tables, notes, and exceptions. They should also learn how related code topics connect. For example, a conductor question may involve ampacity, adjustment factors, terminal temperature limitations, overcurrent protection, and equipment rules. A grounding question may involve grounding electrodes, equipment grounding conductors, bonding jumpers, services, and fault-current path requirements.

A balanced study schedule may rotate between trade review, calculation practice, and NEC navigation. One session might focus on services and feeders. Another might focus on grounding and bonding. Another might involve working electrical calculation problems. Another might involve locating raceway and box requirements in the NEC. This rotation helps students prepare across the full exam outline instead of becoming too comfortable with only one topic area.
