Exam Details

The ICC G17-N National Standard Journeyman Electrician examination contains 80 multiple-choice questions. Candidates are allowed four hours to complete the examination.

The exam is based on the 2017 edition of NFPA 70, the National Electrical Code. Candidates should prepare with the assigned 2017 code because article language, table values, numbering, definitions, and installation requirements may differ in later NEC editions.

Important preparation areas include:

• General electrical knowledge and theory
• Electrical definitions and terminology
• Branch circuits and required outlets
• Feeder calculations and installation requirements
• Services and service equipment
• Load calculations and demand factors
• Conductor ampacity and temperature limitations
• Adjustment and correction factors
• Overcurrent protection
• Grounding and bonding
• Grounding electrode systems
• Raceways, cables, boxes, and fittings
• Box-fill and raceway-fill calculations
• Motors, motor circuits, and controllers
• Transformers and separately derived systems
• Generators and standby systems
• Lighting, appliances, and utilization equipment
• Special occupancies and hazardous locations
• Special equipment and special conditions
• Communications and limited-energy systems

Branch-circuit and feeder questions may require candidates to calculate connected loads, apply demand factors, account for continuous loads, select conductor sizes, and determine overcurrent protection. Preparation should include both dwelling and non-dwelling calculations.

Service questions may involve load calculations, service conductors, service equipment, disconnecting means, grounding, bonding, and equipment ratings. Candidates should practice following a problem from its connected loads through the final conductor and service selection.

Conductor questions may require the use of ampacity tables, terminal-temperature limitations, adjustment factors, ambient-temperature corrections, insulation ratings, and conductor-use requirements. Selecting a conductor from one table is not always the final step.

Motor questions may involve full-load current, branch-circuit conductors, short-circuit and ground-fault protection, overload protection, controllers, disconnecting means, and multiple-motor feeders. Transformer questions may involve primary and secondary conductors, overcurrent protection, grounding, and separately derived systems.

With 80 questions and four hours available, candidates have an average of three minutes per question. Direct code questions may require less time, while calculation and multi-step research questions may require more. Timed practice helps create a balanced testing pace.

Open Book Test

The ICC G17-N National Standard Journeyman Electrician examination is an open-book test. Candidates may use qualifying references in accordance with the current ICC contractor and trades examination policies.

The 2017 National Electrical Code is the central examination reference. Open-book testing still requires familiarity with the code’s organization, definitions, article structure, tables, exceptions, cross-references, and index.

Chapters 1 through 4 contain general requirements that apply broadly to electrical installations. Chapters 5 through 7 address special occupancies, special equipment, and special conditions. Chapter 8 covers communications systems, while Chapter 9 contains tables used for conductor and raceway calculations.

Practice recognizing the likely code location before beginning a search. A service question points toward Article 230. A grounding and bonding question commonly involves Article 250. Motors are addressed in Article 430, transformers in Article 450, and generators in Article 445.

Ugly's Electrical References supports course preparation involving formulas, motors, transformers, voltage drop, conductor properties, grounding, conversions, and common electrical data. Materials taken into the testing environment must comply with the current ICC examination rules.

During practice, read the complete question before opening a reference. Identify whether it asks for a minimum, maximum, permitted, prohibited, or required condition. Locate the applicable rule and review nearby exceptions before choosing an answer.

State Requirements

Missouri does not use one individual statewide journeyman electrician license that replaces every municipal licensing requirement. Jefferson City administers local licenses for apprentices, journeyman electricians, master electricians, and electrical contractors.

Personnel working for an electrical contractor within Jefferson City must hold the applicable City of Jefferson electrical license. The journeyman license is separate from the master electrician and electrical contractor licenses.

The current Jefferson City journeyman application requires documentation of 8,000 hours completed as an electrical apprentice. The hours must be documented on company letterhead by the applicant’s employer or employers and organized to show when the hours were completed.

The current application also requires a passing score of at least 70 percent on an accepted ICC or Prometric journeyman examination based on the 2020 National Electrical Code or a newer NEC edition. A copy of the examination result must accompany the application.

The City’s electrical licensing information page lists the ICC G17 Journeyman Electrician examination among the exams accepted by the Electrical Examiners and Review Board. The G17-N product described on this page is based on the 2017 National Electrical Code, while the current individual license application states that journeyman examination results must be based on the 2020 NEC or newer.

Candidates seeking a new Jefferson City journeyman license should select an examination that meets the code-edition requirement stated on the current application. This G17-N course remains useful for candidates preparing specifically for the 2017 NEC version of the ICC National Standard Journeyman Electrician examination.

Passing an ICC examination does not automatically issue a Jefferson City license. The applicant must complete the municipal application process, document the required apprenticeship hours, provide the score report, pay the applicable fee, and receive approval from the City.

Electrical contracting businesses have additional licensing requirements. A journeyman electrician license does not by itself authorize the holder to operate an electrical contracting business or obtain electrical permits as a licensed electrical contractor.
