The included 2026 NEC allows students to study the same code cycle referenced by the current Colorado examination. NEC tabs help organize important articles and tables during preparation, while the Master Electrician Study Guide provides advanced trade review and the Calculations Study Guide focuses on mathematical problem solving.

Flash cards provide active-recall practice for definitions, formulas, terminology, and electrical concepts. The online course adds instructor-led NEC education, simulated practice examinations, an organized NEC overview, live instructional videos, and recorded lessons that can be reviewed around a working electrician’s schedule.

Exam Details

The Colorado Master Electrician examination is administered by PSI for the Colorado State Electrical Board. The current examination is computer based and evaluates the knowledge required for entry into professional practice as a licensed Colorado Master Electrician.

The Master Electrician examination contains 90 scored questions and allows 240 minutes, or four hours, for the scored portion. The examination may also contain up to 10 non-scored questions, with additional time provided for those questions.

Candidates must correctly answer at least 63 of the 90 scored questions, equivalent to 70 percent, to pass the Master Electrician examination.

Grounding and Bonding is the largest individual content category with 14 scored questions. Candidates should understand grounding electrode systems, equipment grounding, bonding jumpers, separately derived systems, service bonding, enclosures, raceways, and effective ground-fault current paths.

Services, Feeders, and Branch Circuits contain 11 questions. Preparation should include service calculations, feeder loads, branch-circuit requirements, conductor sizing, disconnecting means, overcurrent protection, grounding, required circuits, and electrical distribution systems.

Special Occupancies and Special Equipment each contain nine questions. Master-level candidates should understand when specialized NEC provisions modify or supplement general wiring requirements and how those rules interact with ordinary installation standards.

Electrical Calculations account for nine questions. Candidates should be prepared to work with load calculations, conductor ampacity, voltage, current, resistance, power, motors, transformers, services, feeders, branch circuits, raceway fill, box fill, and related formulas.

Motors account for eight questions. Preparation should include motor conductors, overload protection, short-circuit and ground-fault protection, controllers, disconnecting means, motor calculations, and applicable tables.

Additional examination areas include General Electrical Knowledge, Overcurrent Protection, Conductors and Cables, Raceways and Boxes, Special Conditions, Electrical Devices, and Transformers.

Effective August 1, 2026, all Colorado electrician licensing examination questions are consistent with the 2026 National Electrical Code. Candidates should therefore build their exam preparation around the organization and requirements of the 2026 NEC.

Open Book Test

The Colorado Master Electrician examination uses the National Electrical Code as an examination reference. The 2026 NEC and a formula page are provided to candidates at the PSI testing center for examinations based on the 2026 code cycle.

Candidates do not bring their personal NEC book, tabs, study guides, or other reference materials into the examination room. PSI provides the authorized code book and formula page used during the test.

Candidates may not write in, highlight, underline, or index the provided examination references. No additional reference materials are permitted.

This makes preparation with the included 2026 NEC especially valuable. Although candidates cannot bring their personal tabbed book into the official examination, repeated study with tabs can help develop a mental map of the NEC so the candidate knows where to look when using the testing-center copy.

Students should practice navigating Article 100 definitions, branch circuits, feeders, services, grounding and bonding, conductor tables, wiring methods, motors, transformers, equipment, special occupancies, special equipment, and special conditions.

Use the NEC table of contents and index as part of regular practice. Become familiar with article numbering, table locations, exceptions, informational notes, cross-references, and the relationship between general rules and specialized requirements.

Because the examination includes a dedicated calculation category, candidates should also practice working from the formula page and applying electrical theory to code-based problems. Knowing where a value comes from in the NEC is just as important as knowing the mathematical formula.

The Master Electrician Study Guide, Calculations Study Guide, flash cards, tabs, simulated practice exams, live videos, and recorded videos are preparation tools and are not personal exam-room references for the Colorado PSI examination.

Licensing Steps

Begin by determining which Colorado Master Electrician experience pathway matches your education and electrical work history.

The primary experience pathway requires 10,000 hours of qualifying electrical experience earned over no less than five years. Applicants using this pathway must document qualifying experience that satisfies Colorado’s requirements for master-level licensure.

Colorado also provides an education-based pathway for applicants with a bachelor’s degree in electrical engineering from an accredited college or university. This pathway requires an additional 2,000 hours of qualifying construction experience earned over at least one year.

Another pathway is available to graduates of qualifying electrical trade schools or community colleges. These applicants must document 8,000 hours of qualifying electrical experience earned over no less than four years.

Experience must be documented according to Colorado State Electrical Board requirements. Applicants should maintain accurate records of employment, electrical duties, hours worked, employers, supervision, and applicable training.

Colorado does not permit supervision hours to be counted a second time toward the total experience requirement when the same hours have already been credited for electrical work performed alongside the individuals being supervised.

Applicants using practical experience to qualify for the Master Electrician license must follow the progression requirements established by the Board. Colorado specifically notes that an applicant cannot move directly from Apprentice or Residential Wireman to Master using the experience-only qualification pathway.

Register for the Colorado Master Electrician examination through PSI when eligible. Colorado’s licensing process allows candidates to complete the examination and then submit the license application demonstrating that all minimum qualifications have been satisfied.

Prepare for the examination using the 2026 NEC, Master Electrician Study Guide, Calculations Study Guide, flash cards, NEC overview, live instruction, recorded lessons, and simulated practice exams.

Practice full examination sessions using a four-hour target for 90 scored questions. This helps develop the pacing needed to balance direct knowledge, calculations, and NEC research.

After passing the examination, submit the Master Electrician license application and required documentation to the Colorado Division of Professions and Occupations. Passing the examination is one part of the licensing process; the applicant must also establish that the statutory qualification requirements have been satisfied.

State Requirements

Colorado licenses Residential Wiremen, Journeyman Electricians, and Master Electricians through the Colorado State Electrical Board. The Master Electrician license is the most advanced individual electrical license administered by the Board.

Colorado defines a Master Electrician as an individual with the qualifications, training, experience, and technical knowledge necessary to properly plan, lay out, and supervise the installation and repair of electrical wiring, apparatus, and equipment.

Electrical contracting is regulated separately from the individual Master Electrician license. A business that performs electrical contracting in Colorado must be registered as an Electrical Contractor with the state.

A Colorado Electrical Contractor must hold or employ a licensed Master Electrician to serve as the responsible individual for the company. The designated Master Electrician may serve as the responsible party for only one electrical contracting company.

The standard Master Electrician experience pathway requires 10,000 hours earned in no less than five years. Alternative pathways recognize qualifying electrical engineering education or graduation from an electrical trade school or community college together with the required construction experience.

Colorado electrician examinations transitioned to the 2026 NEC on August 1, 2026. PSI provides the 2026 NEC and a formula page at the examination center for candidates testing under the current cycle.

Colorado’s currently published statewide electrical rule still identifies the 2023 NEC as the incorporated minimum installation standard while the Board’s 2026 code-adoption rulemaking proceeds through the state regulatory process. Candidates should distinguish between the NEC edition currently used on the licensing examination and the code edition legally adopted for a particular electrical installation.

Colorado Master Electricians must complete at least 24 hours of approved continuing education during each three-year license period. The requirement also applies to licensed Journeyman Electricians and Residential Wiremen.

At least four continuing-education hours must cover National Electrical Code changes. Continuing education may also address grounding and bonding, wiring methods, electrical theory and calculations, and electrical safety within the limits established by Board rules.

The first renewal of a license issued after successful completion of a licensing examination is exempt from the continuing-education requirement for that renewal cycle.
