Current Colorado PSI format: the Journeyman Wireman exam has 90 scored questions, 240 minutes, and a 70% or 63-correct passing requirement. PSI may add up to 10 unscored questions with up to 30 additional minutes. The 2026 NEC has been the standard exam code since August 1, 2026.
What Is the Colorado Journeyman Electrician Exam?
The Colorado Journeyman Wireman examination is the state licensing test administered by PSI for the Colorado State Electrical Board. It tests NEC knowledge, electrical calculations, grounding and bonding, wiring methods, conductors, motors, transformers, equipment, occupancies, photovoltaics, and general electrical theory.
Short answer: the current PSI exam contains 90 scored questions, allows 240 minutes, and requires 63 correct scored answers. PSI supplies the 2026 NEC and Formula Page at the testing center.
The exam's five biggest categories account for 51 scored questions, so a strong exam prep plan should prioritize Grounding and Bonding, General Electrical Knowledge, Services/Feeders/Branch Circuits, Electrical Calculations, and Conductors/Cables.
This guide combines current PSI testing information, Colorado experience requirements, classroom-training rules, contractor registration distinctions, 2026 NEC navigation, calculation practice, and structured contractor exam prep without pricing.

Practice like the real PSI exam. Your study system should not depend on personal NEC tabs because PSI supplies the code book used in the testing room.
Know the NEC structure. Practice article, section, table, informational note, definition, and exception lookup.
Use the Formula Page wisely. Know which formula applies before reaching for the calculator.
Prioritize the heavy domains. The five largest categories account for 51 scored questions.
Electrical Calculations, NEC Navigation and Code Lookup Strategy
The Colorado Journeyman Wireman exam rewards candidates who can recognize the electrical topic, locate the correct NEC rule, use the supplied Formula Page when needed, and complete calculations without wasting time.
Simplified study illustration for NEC lookup, calculations, grounding, services, and motor practice.
Train each practice question as a lookup sequence: identify the subject, choose the most likely NEC article or table, use the Formula Page when needed, complete the calculation, verify the code rule, and move on.
- Grounding and Bonding: 14 scored questions.
- General Electrical Knowledge: 11 scored questions.
- Services, Feeders, and Branch Circuits: 9 scored questions.
- Electrical Calculations: 9 scored questions.
- Conductors and Cables: 8 scored questions.
| Skill | What to Practice | Common Mistake |
|---|---|---|
| Clean NEC navigation | Article recognition, index terms, sections, tables, definitions and exceptions | Depending on personal tabs that will not be in the test-center NEC |
| Grounding and bonding | Electrode conductors, equipment grounding conductors, bonding jumpers and separately derived systems | Using the wrong sizing table or confusing grounding with bonding |
| Electrical calculations | Ohm's Law, power, three-phase, loads, motors, transformers and conductor sizing | Choosing the wrong formula or applying the wrong units |
| Conductors and cables | Ampacity, correction, adjustment, insulation and terminal limitations | Skipping the conditions that change allowable ampacity |
| Motors and transformers | FLC tables, conductor sizing, protection, current relationships and disconnect rules | Using nameplate values where the NEC requires table values |
| Time management | Timed blocks, flag-return strategy and 240-minute stamina | Spending too long on one calculation or code lookup |
Practice the path, not only the answer. After every missed exam-prep question, record the NEC article, table, calculation method, setup error, and reason the original answer failed.

How to Prepare for the PSI-Supplied 2026 NEC
Winning NEC navigation habits
- Practice in a clean 2026 NEC before test day
- Know article organization and index terms
- Practice table selection and exception lookup
- Use the Formula Page during realistic calculation practice
- Review grounding, conductors, services, motors and transformers
- Complete timed exam prep under the full 240-minute limit
Avoid these exam-prep mistakes
- Depending on personal tabs and highlights
- Studying only the 2023 NEC after the August 2026 transition
- Memorizing answers instead of learning article and table paths
- Ignoring calculations because PSI supplies formulas
- Under-studying grounding and bonding
- Spending too long on one calculation or code lookup
Current PSI rule: the 2026 NEC and Formula Page are provided at the testing center, and candidates may not write in, highlight, underline, or index those supplied references.
Journeyman Electrician License vs Electrical Contractor Registration
The Colorado Journeyman Electrician license is an individual credential. An electrical contractor registration is a separate business credential.
Colorado requires an electrical contractor to have a licensed Master Electrician who is responsible for supervising all electrical work. The responsible Master must be actively engaged with the contracting company and may be responsible for only one contractor.
That means a candidate searching for Colorado Journeyman Electrician contractor exam prep should understand both layers: the PSI exam for the individual license and the separate contractor registration rules for the business.
Colorado Journeyman Electrician vs Master Electrician vs Electrical Contractor
These credentials and business roles are connected, but they are not interchangeable.
| Path | Focus | Important Note |
|---|---|---|
| Journeyman Electrician | Individual electrician license | Requires qualifying experience, classroom training and PSI exam |
| Master Electrician | Higher individual electrical license | Can serve as responsible Master for an electrical contractor |
| Electrical Contractor Registration | Business authority to contract for electrical work | Requires responsible Master Electrician structure |
| PSI Journeyman Wireman Exam | 2026 NEC knowledge, calculations and code application | Passing alone does not complete the full license process |
| Contractor Exam Prep | Study, practice, clean-code navigation and exam strategy | Study support, not a state-issued credential |
Confirm the credential first. Journeyman exam prep prepares for the individual license exam. Contractor registration requires a separate responsible-Master structure.

How Hard Is the Colorado Journeyman Electrician Exam?
The challenge is the combination of 90 scored questions, the 2026 NEC, electrical calculations, code navigation, and a 240-minute scored-exam time limit.
Common avoidable problems include weak grounding prep, code-cycle confusion, dependence on personal tabs, slow three-phase math, conductor-sizing errors, and spending too long on one code search. Structured contractor exam prep turns those problems into measurable practice goals.
