Exam Details

The Colorado Journeyman Wireman examination is administered by PSI for the Colorado State Electrical Board. Colorado’s licensing examinations for Residential Wireman, Journeyman Wireman, Master Electrician, and certain long-term apprentices are computer-based examinations administered through PSI testing centers.

The Colorado Journeyman Wireman examination is based on the 2023 National Electrical Code. The exam includes 90 scored items and allows 240 minutes for the scored portion. The passing standard is 70%, which means 63 scored items correct. The exam may also include up to 10 non-scored items, with additional time added for those items. Non-scored items are used for exam development and do not count toward the final score.

The Colorado 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. This broad outline means candidates should prepare across the full scope of journeyman-level electrical work instead of focusing only on a few high-comfort topics.

General Electrical Knowledge may include electrical theory, formulas, symbols, basic circuit behavior, trade terminology, measurements, and practical field concepts. Services, feeders, and branch circuits may include load requirements, conductor sizing, service equipment, disconnecting means, branch-circuit ratings, feeder rules, and overcurrent protection. Grounding and bonding may include grounded conductors, equipment grounding conductors, bonding jumpers, grounding electrode systems, fault-current paths, and separately derived systems.

Conductors and cables may include ampacity, insulation, temperature limitations, conductor material, conductor protection, cable wiring methods, and installation rules. Raceways and boxes may include conduit types, raceway fill, box fill, pull boxes, supports, fittings, bends, and practical installation requirements. Motors, transformers, electrical devices, photovoltaics, and special installations require both NEC familiarity and practical trade understanding.

Electrical calculations are an important part of the Colorado Journeyman Wireman exam. Candidates should be prepared to work problems involving Ohm’s law, Watt’s law, volt-amperes, conductor sizing, ampacity adjustment, box fill, raceway fill, motor calculations, voltage drop concepts, service and feeder calculations, branch circuit calculations, and overcurrent protection. Calculation practice should be part of the weekly study routine, not saved for the final stage of preparation.

Open Book Test

The Colorado Journeyman Wireman examination is an open book exam with strict reference rules. PSI provides the 2023 National Electrical Code book and a formula page at the test center. Candidates may not write, highlight, underline, index, or add markings to the references provided at the test center, and no other materials may be used during the examination.

Open book testing does not make the Colorado exam easy. Candidates still need to know how to locate information quickly, understand NEC structure, interpret code language correctly, and apply the correct rule to the question being asked. A candidate who relies on searching the code book for every answer may lose valuable time during the 240-minute scored portion of the exam.

The National Electrical Code 2023 Paperback with Tabs included in this Ultimate Combo is a study and code navigation tool for preparation. Candidates should use it before exam day to become familiar with NEC chapters, articles, tables, definitions, notes, exceptions, and calculation pathways. The goal is to build code fluency so that the provided exam reference is easier to use under timed conditions.

During preparation, practice locating definitions, services, feeders, branch circuits, grounding and bonding, conductor ampacity tables, wiring methods, raceways, boxes, overcurrent protection, motors, transformers, photovoltaic systems, special occupancies, special equipment, electrical devices, and Chapter 9 tables. Strong code familiarity helps candidates recognize where to look and how to apply the information once they find it.

For open-book preparation, study the NEC in layers. Start by learning the chapter layout and major article structure. Next, practice finding common topics quickly. Add timed lookup drills to build speed. Then combine code lookup with exam-style questions so you learn when to rely on memory, when to use the code book, and when to move forward to protect your exam time.

Licensing Steps

The Colorado journeyman electrician licensing path begins with meeting the experience and education requirements for the Journeyman Wireman license. Colorado identifies 8,000 hours of experience earned in no less than four years for journeyman applicants. At least 2,000 of those hours must be in commercial or industrial work. Colorado also requires 288 hours of classroom education for all journeyman applicants, documented by transcript or a similar statement.

The first step is to document qualifying electrical work experience. Candidates should keep accurate records of employers, dates of employment, job duties, supervision, and work categories. Colorado requires the experience to meet the standards for the license being requested, and documentation must support the hours claimed in the application.

The next step is to document classroom education. The 288 classroom hours should be supported by a transcript or similar education record. Candidates should organize this documentation before applying so the application process is smoother and the board can evaluate the file accurately.

After the applicant has the required experience and education documentation, the applicant applies through the Colorado electrical licensing process. Colorado’s licensing authority reviews the application and supporting documentation. Passing the exam alone does not guarantee licensure; applicants must still meet the minimum qualifications set by Colorado law and board rules.

After meeting the application and examination requirements, the candidate schedules the exam through PSI. Candidates should follow PSI’s instructions for registration, examination scheduling, identification, testing center rules, exam fees, rescheduling, and score reporting.

On exam day, candidates should bring the required identification and follow all PSI testing center rules. PSI provides the NEC reference and formula page used during the exam. Personal reference books, notes, study guides, practice exams, electronic devices, and unauthorized materials are not allowed in the testing room.

After passing the exam and satisfying Colorado’s licensing requirements, candidates complete any remaining steps required by the Division of Professions and Occupations. Final license issuance, license status, and renewal are controlled by the Colorado State Electrical Board and the Division.

State Requirements

Colorado regulates electrician licensing statewide through the Colorado State Electrical Board. The state licenses Residential Wiremen, Journeyman Wiremen, Master Electricians, electrical contractors, and related electrical categories. The Journeyman Wireman license is the statewide journeyman-level credential for electricians who qualify through experience, education, and examination.

Colorado’s Journeyman Wireman requirements include 8,000 hours of experience earned in no less than four years. At least 2,000 hours must be in commercial or industrial work. Colorado also requires 288 hours of classroom education for all journeyman applicants, documented with a transcript or similar statement.

Colorado also has a Residential Wireman license for work within the allowed residential scope and a Master Electrician license for higher-level qualification. A person planning to operate an electrical contracting business must also understand Colorado’s electrical contractor registration requirements. 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.

Colorado participates in journeyman electrician reciprocal licensing through the National Electrical Reciprocal Alliance with participating states. Reciprocal licensing is limited to applicants who meet Colorado’s reciprocity requirements, including holding an active qualifying license gained through a state-administered examination. Reciprocity does not apply to licenses granted only by grandfathering without an examination.

Licensed Colorado electricians should continue monitoring renewal requirements, continuing education expectations, code adoption, and board rules after obtaining a license. Electrical codes and licensing rules can change over time, and responsible electricians remain current with code updates, safe work practices, and regulatory requirements.
