Exam Details

The Colorado State Electrical Board contracts with PSI Services LLC to administer the Residential Wireman, Journeyman Wireman, Master Electrician, and six-year apprentice electrical examinations. PSI’s Colorado State Electrical Board Candidate Information Bulletin identifies the Master Electrician examination as a computer-based exam with scored and non-scored items.

The Colorado Master Electrician examination includes 90 scored items with a time allowance of 240 minutes. The passing standard is 70%, which equals 63 correct scored items. The examination may also include up to 10 non-scored items, with an additional 30 minutes added for those items. Non-scored items are used for exam development and are not counted toward the candidate’s final score.

The Colorado Master Electrician content outline includes general electrical knowledge, services, feeders, and branch circuits, grounding and bonding, overcurrent protection, conductors and cables, raceways and boxes, special conditions, special occupancies, special equipment, electrical devices, motors, transformers, and electrical calculations. Grounding and bonding, services and feeders, special occupancies, special equipment, motors, and calculations are especially important areas because they represent a meaningful portion of the master-level exam outline.

PSI states that Colorado electrical licensing examinations use the National Electrical Code edition identified in the candidate bulletin. The 2026 NEC becomes the listed examination reference for Colorado electrical exams effective August 1, 2026. This product is based on the 2026 National Electrical Code and is designed for candidates studying with the 2026 NEC.

The examination is delivered by computer. Candidates receive an introductory tutorial before the exam begins, and that tutorial time does not count against the examination time. Scores are provided immediately after completion of the examination. Candidates should follow PSI’s current scheduling, identification, testing-center, calculator, and security rules for the exam appointment.

Open Book Test

The Colorado electrical licensing examinations use an open-reference format with the approved code book and formula page provided at the test center. PSI’s Colorado bulletin states that the National Electrical Code book and formula page are provided to candidates at the testing center. Candidates may not bring or use other materials for the examination.

For exams using the 2026 NEC, PSI states that the 2026 National Electrical Code book and formula page are provided at the test center. Candidates may not write, highlight, underline, or index on the references. Candidates also may not use any other materials during the examination. This means the NEC paperback and tabs included in this product are for study preparation, code familiarity, and practice before exam day, not for personal exam-room use.

Because the exam reference is provided at the testing center, candidates should use this combo to become familiar with NEC organization before the exam. Studying with a tabbed NEC can still be valuable because it teaches candidates how the code is arranged, where major topics appear, and how sections relate to each other. During preparation, candidates can use the tabs to build stronger code-location habits, then rely on that familiarity when working with the provided reference during the actual exam.

Electrical theory and common formulas are also important. PSI advises candidates to review electrical theory and formulas because that knowledge may be required in the calculations portion of the examination. Candidates should practice calculations regularly and learn how to recognize when a question is testing load calculations, conductor sizing, grounding and bonding, motor requirements, transformer concepts, or another NEC-based topic.

Licensing Steps

The Colorado master electrician licensing process begins with meeting the state’s experience requirements. Colorado lists multiple ways to qualify for the Master Electrician license by examination. Candidates may qualify through 10,000 hours of experience earned in no less than five years, a bachelor’s degree in electrical engineering plus qualifying construction experience, graduation from an electrical trade school or community college plus qualifying experience, or additional experience beyond the journeyman requirements.

All practical experience must be documented on the Affidavit of Experience form provided by the Board and completed by the electrical contractor supervising the work performed. Colorado notes that journeyman electricians cannot be a signatory authority for a company. For candidates using the journeyman-plus-experience path, the state identifies additional experience beyond the journeyman requirements, including some hours in planning and layout and some supervision while in possession of a Journeyman Electrician license.

After meeting the applicable qualifications, candidates complete the appropriate electrical license application process through the Colorado Division of Professions and Occupations. PSI provides the examination program for the Colorado State Electrical Board. Candidates schedule and take the examination through PSI according to the current candidate bulletin.

After passing the examination, candidates file a license application with the Division of Professions and Occupations. Passing the exam is not the same as being licensed. The state reviews whether the applicant meets the minimum qualifications for licensure under Colorado law. Candidates should keep documentation organized, including experience affidavits, education records when applicable, and any required application materials.

Electricians who plan to perform electrical contracting in Colorado must also pay attention to electrical contractor registration requirements. To perform electrical contracting in Colorado, a business must be registered as an electrical contractor and must hold or employ a licensed master electrician to serve as the responsible individual for the company.

State Requirements

The Colorado State Electrical Board licenses, registers, and regulates electricians, apprentices, and electrical contractors. The Board’s role includes protecting public health and safety by enforcing Colorado electrical statutes, conducting inspections of regulated installations, and reviewing certain code-related requests.

Colorado’s Master Electrician experience requirements allow several qualification paths. One path requires 10,000 hours of experience earned in no less than five years. Another path allows a bachelor’s degree in electrical engineering from an accredited college or university plus 2,000 hours of construction experience earned in no less than one year. A third path allows graduation from an electrical trade school or community college plus 8,000 hours of experience earned in no less than four years. Another path allows additional qualifying experience beyond the journeyman requirements, including planning and layout and supervision while holding a Journeyman Electrician license.

Colorado also has specific rules for electrical contractors. An electrical contractor must hold or employ a licensed master electrician to serve as the responsible individual for the company. The master electrician and company owner, when they are separate individuals, must sign an Acknowledgment of Responsibility form. The selected master electrician may be the responsible party for only one company.

Electrical contractors must also submit evidence of compliance with workers’ compensation and unemployment compensation laws. Local requirements may also apply depending on the city or county where the work is performed. Candidates and business owners should review both state and local requirements before performing electrical contracting work.

Colorado licensees must also pay attention to continuing education. Active Residential Wireman, Journeyman Electrician, and Master Electrician licensees must complete at least 24 hours of continuing education during each three-year license period. Continuing education is part of maintaining an active license after the exam and licensing process are complete.

Reference Books

• National Electrical Code 2026 Paperback
  A printed NEC reference used for studying electrical code layout, definitions, wiring methods, grounding and bonding, services, feeders, branch circuits, overcurrent protection, conductors, raceways, motors, transformers, special occupancies, special equipment, electrical devices, and calculation-related code requirements.

Test Information and Study Materials

The 2026 Colorado Master Electrician Study Guide & National Electrical Code Combo with Tabs supports a practical exam-preparation routine. Candidates can use the study guide to review major exam areas and the NEC paperback to reinforce the code concepts behind those areas. The tabs help organize the code book so repeated study sessions become more efficient.

A strong master electrician study plan should include code review, calculation practice, theory review, and timed exam-style repetition. Code review helps candidates understand how NEC articles are arranged and how to connect a question to the correct section. Calculation practice helps candidates prepare for load calculations, conductor sizing, grounding and bonding values, motor calculations, transformer questions, and other math-based topics. Theory review helps reinforce electrical principles that may not be solved by code lookup alone.

Grounding and bonding is one of the most important Colorado Master Electrician study areas. Candidates should review grounding electrode systems, bonding jumpers, equipment grounding conductors, service bonding, separately derived systems, grounding terminology, and related NEC tables. These questions often require careful reading because similar terms can lead to different answers.

Services, feeders, and branch circuits also deserve focused review. Candidates should understand service equipment, feeder sizing, branch circuit requirements, conductor protection, load calculations, and the relationship between overcurrent devices and conductor ampacity. These topics appear throughout electrical work and are central to advanced licensing preparation.

Raceways, boxes, conductors, special occupancies, special equipment, motors, transformers, and electrical devices require repeated practice because they cover a wide range of installations. Candidates should study not only the rule itself, but also when the rule applies. A question may change based on the equipment type, location, voltage, occupancy, wiring method, or installation condition.

The NEC tabs included in this combo help candidates create a study system. Students can mark major NEC articles, definitions, tables, grounding and bonding rules, service and feeder sections, wiring methods, conductors, motor rules, transformer requirements, special occupancies, special equipment, and calculation-related areas. The goal is to become more fluent with the NEC during preparation so the code book feels less overwhelming.
