1.1 Colorado Electrical Board, Licensure Tiers & Application Process

1.1 Colorado Electrical Board, Licensure Tiers & Application Process

Exam Fast Fact: Colorado will not let an applicant with only residential wiring experience sit for the Journeyman Wireman examination. Under C.R.S. 12-115-110(2)(a), a candidate must document 8,000 hours of practical experience over at least 4 years, and 2,000 of those hours, earned over at least 2 years, must be in commercial, industrial, or substantially similar work. Watch the trap: the commercial/industrial minimum is 2,000 hours, not half the total.

Electrical licensing in Colorado is a statutory regulatory mandate, not a professional courtesy. The state runs a single centralized licensing system that governs individual competency from an apprentice's first day on a jobsite through master electrician licensure and electrical contractor registration.

Statutory Authority: DORA and C.R.S. Title 12, Article 115

Electrical licensing is administered by the Department of Regulatory Agencies (DORA) through its Division of Professions and Occupations (DPO). The enabling statute is the Electricians Practice Act, codified at C.R.S. Title 12, Article 115 (sections 12-115-101 through 12-115-124). The Board's administrative rules are published as 3 CCR 710-1.

Composition of the State Electrical Board (C.R.S. 12-115-104)

The Colorado State Electrical Board has nine members appointed by the Governor with the consent of the Senate, all of whom must be Colorado residents. Seats are allocated by statute:

Members serve three-year terms and are limited to two full terms. The Governor is directed to strongly consider appointing an electrician who works primarily in the residential sector to at least one of the four electrician seats.

Core Powers and Duties of the Board

Under C.R.S. 12-115-107 the Board may:

1. Incorporate the National Electrical Code by reference. Board Rule 1.5 currently incorporates NFPA 70, 2026 Edition, effective August 1, 2026, as the minimum statewide installation standard.
2. Issue, renew, and discipline licenses for residential wiremen, journeyman electricians, and master electricians, and registrations for apprentices, electrical contractors, and photovoltaic installers.
3. Provide for licensing examinations under C.R.S. 12-115-110(4), approve the examination content, and set the passing score. The Board has contracted this function to PSI Services LLC.
4. Investigate and enforce through inspections, compliance checks, cease-and-desist orders, and the civil penalty schedule in the Board rules.

Journeyman Electrician Qualification Requirements

An applicant approved to sit for the PSI Journeyman Wireman examination must satisfy three statutory pillars under C.R.S. 12-115-110(2)(a).

1. Eight Thousand Hours Over at Least Four Years — 12-115-110(2)(a)(I)

The applicant must document 8,000 hours of apprenticeship in the electrical trade, or 8,000 hours of practical experience wiring for, installing, and repairing electrical apparatus and equipment for electric light, heat, and power, earned over a period of not less than four years. Four years is roughly 2,000 hours per full-time work year, so the hour total and the calendar span are effectively simultaneous requirements — you cannot compress 8,000 hours of overtime into three years and qualify.

2. Two Thousand Commercial/Industrial Hours Over at Least Two Years — 12-115-110(2)(a)(II)

At least 2,000 hours of the 8,000, earned over at least two years, must be in commercial, industrial, or substantially similar work.

• What counts: three-phase distribution, commercial branch circuits and feeders, conduit bending and installation, commercial service entrances, motor control, switchboards and panelboards, transformers, classified locations, and commercial lighting control.
• Why it exists: the journeyman license authorizes work in every occupancy class. The Board will not certify unlimited scope on residential-only evidence.
• The consequence: a candidate with 16,000 hours of tract-home wiring and zero commercial hours qualifies only for the Residential Wireman license until 2,000 commercial/industrial hours are logged.

3. Two Hundred Eighty-Eight Training Hours in the Last Eight Years — 12-115-110(2)(a)(III)

Every journeyman applicant must document at least 288 hours of training in safety, the National Electrical Code and its application, and any other subject the Board requires. Senate Bill 25-165 widened the window from the last four years to the last eight years of the applicant's training, apprenticeship, or practical experience. The Division states that the 288 hours apply to all applicants and that there is no grandfathering of any apprentice registration.

Board Rule 1.7(D) fixes the content and the ground rules:

• Subject matter must include grounding and bonding, National Electrical Code changes, wiring methods, theory and calculations, and a minimum of ten and maximum of forty hours of OSHA curriculum.
• One credit hour means not less than fifty minutes of structured instruction.
• Training must be documented by transcript, certificate of completion, or equivalent statement.
• The Board does not pre-approve courses or programs. Keep the documentation; the Board evaluates it at application time.
• The 288 hours are in addition to the on-the-job hour requirement, not a substitute for any of it.

Where an applicant completed qualifying training before the eight-year window, the Board may still grant credit if the applicant proves at least four additional hours of training on the current or immediately previous NEC edition.

Experience Substitutions — 12-115-110(2)(b)

• A graduate electrical engineer of an accredited college or university, or a graduate of a Board-approved community college or trade school program, receives one year of work experience credit.
• For other academic training, including military training and photovoltaic installation training, the Board may grant work experience credit. Senate Bill 25-165 converted this from a mandatory duty into discretionary authority, so assume nothing until the Board rules on your file. Board rules credit qualifying photovoltaic work at two hours of PV work per one hour of electrical experience, capped at 2,000 hours.

Master Electrician and Electrical Contractor Requirements

Master Electrician Pathways (C.R.S. 12-115-110(1))

An applicant qualifies by meeting any one of the following:

1. 10,000 hours of experience earned over no less than 5 years; or
2. A bachelor's degree in electrical engineering from an accredited college or university plus 2,000 hours of construction experience earned over no less than 1 year; or
3. Graduation from an electrical trade school or community college plus 8,000 hours earned over no less than 4 years; or
4. The journeyman requirements plus 2,000 additional hours earned over no less than 1 year in planning, laying out, and supervising installations. Supervision hours performed alongside supervisees are not double-counted toward the total.

You cannot move from apprentice or residential wireman directly to master using the experience route.

Electrical Contractor Registration

An Electrical Contractor is a business registration, not a personal credential. To register, the entity must:

• Hold or employ a licensed Colorado master electrician as the responsible individual for the company. The master and the owner, if different people, sign an Acknowledgment of Responsibility form, and that master may be the responsible party for only one company.
• Submit evidence of compliance with Colorado workers' compensation and unemployment compensation laws.

Application Workflow and the Affidavit of Experience

[Register as an apprentice with the Board before performing electrical work]
                      |
[Log practical hours by category: residential vs. commercial/industrial]
                      |
[Complete 288 hours of qualifying classroom training]
                      |
[Affidavit of Experience completed by the supervising electrical contractor]
                      |
[Initial license application filed through DPO Online Services]
                      |
[Board staff review and approval to test]
                      |
[Schedule and sit the PSI Journeyman Wireman examination]
                      |
[Pass at 70%, then complete licensure with the Division]

The Affidavit of Experience is the Board's own form and the heart of the file. Board Rule 1.7 requires it to state hours by category (commercial, residential, industrial, and maintenance/service) in increments of hours and months, and to be signed by the master electrician for, or a signatory authority of, the electrical contractor or employer. Applicants cannot verify their own experience, and a journeyman electrician cannot be the signatory authority for a company.

Renewal, Endorsement, and Reciprocity

• Licenses and contractor registrations expire September 30 every three years, on a cycle aligned to the Board's NEC adoption. Active licensees complete 24 hours of continuing education per period, including at least 4 hours on NEC changes, with no more than 4 hours credited to safety training. The requirement does not apply to the first renewal after initial licensure by examination.
• Endorsement requires an active, state-issued license earned by testing on the NEC edition currently in use in Colorado.
• Reciprocity runs through the National Electrical Reciprocal Alliance (NERA). Colorado has journeyman reciprocity with Alaska, Arkansas, Idaho, Iowa, Minnesota, Montana, Nebraska, New Hampshire, New Mexico, North Dakota, Oklahoma, South Dakota, Utah, and Wyoming. The out-of-state license must have been earned by passing a state-administered examination and held for at least one year; grandfathered licenses do not qualify.
