Prepare for the ICC T17-N National Standard Journeyman Electrician examination with a flexible training program that combines a complete online self-study course, recorded instruction, and live virtual classes. The training is organized around the 2020 National Electrical Code and covers electrical theory, code navigation, calculations, services, feeders, branch circuits, conductors, wiring methods, grounding, bonding, overcurrent protection, motors, transformers, generators, control devices, equipment, and special electrical installations.

The ICC T17-N examination is a National Standard Journeyman Electrician exam associated with the 2020 edition of NFPA 70, the National Electrical Code. It evaluates a candidate’s ability to locate, interpret, and apply electrical requirements in a timed testing environment. Candidates need practical trade knowledge, electrical calculation skills, and an organized method for using NEC articles, definitions, tables, exceptions, notes, and cross-references.

Journeyman electrician exam preparation involves more than memorizing individual code sections. Electrical questions often require candidates to combine several rules. A conductor-sizing problem may involve the calculated load, continuous-load requirements, conductor ampacity, terminal-temperature limitations, correction factors, adjustment factors, overcurrent protection, and an equipment-specific provision found elsewhere in the NEC.

Practical electrical experience provides an important foundation, but a timed code examination also requires efficient reference navigation. Candidates should be able to identify the subject of a question, select the likely NEC article or table, locate the controlling provision, review applicable exceptions, complete the required calculation, and move forward without spending too much time on one item.

This Jefferson City Missouri Journeyman Electrician exam prep program provides three connected ways to study. The complete online course offers an organized self-paced path through the major examination subjects. Recorded classes allow students to pause technical explanations, repeat calculations, and revisit NEC navigation demonstrations.

Exam Details

The ICC T17-N National Standard Journeyman Electrician examination is based on the 2020 National Electrical Code. The examination contains 80 multiple-choice questions, and candidates are allowed four hours to complete it.

The examination evaluates journeyman-level knowledge across a broad range of electrical systems and installation requirements. Candidates should prepare for direct code questions, electrical calculations, equipment applications, and questions requiring research across multiple NEC articles or tables.

Major areas of preparation include:

• General Knowledge: Electrical theory, terminology, calculations, safety concepts, and general code requirements.
• Services and Service Equipment: Service conductors, service disconnects, calculated loads, equipment ratings, grounding, bonding, and overcurrent protection.
• Feeders: Feeder loads, conductors, ampacity, overcurrent protection, grounding, and installation requirements.
• Branch Circuits and Conductors: Required circuits, outlet requirements, connected loads, continuous loads, conductor sizing, insulation, ampacity, and protection.
• Wiring Methods and Materials: Raceways, cables, boxes, fittings, conductor support, physical protection, environmental conditions, and permitted uses.
• Equipment and Devices: Appliances, luminaires, heating equipment, transformers, panelboards, switches, receptacles, disconnects, and utilization equipment.
• Control Devices: Relays, contactors, starters, controllers, switches, disconnecting means, and control circuits.
• Motors and Generators: Conductors, short-circuit and ground-fault protection, overload protection, controllers, disconnects, and feeder calculations.
• Special Occupancies, Equipment, and Conditions: Hazardous locations, emergency systems, standby systems, healthcare spaces, renewable-energy equipment, and specialized installations.

Wiring methods and materials represent an important part of journeyman electrician preparation. Candidates should understand the permitted and prohibited uses of common raceways and cable systems, conductor support, protection from physical damage, wet-location requirements, box sizing, raceway fill, and installation restrictions.

Branch-circuit questions may involve connected loads, continuous loads, required receptacles, lighting circuits, conductor sizing, overcurrent protection, insulation ratings, and equipment requirements. Candidates should practice determining whether an equipment-specific article modifies a general branch-circuit rule.

Service and feeder questions may require candidates to calculate loads, apply demand factors, select conductors, determine overcurrent protection, evaluate disconnecting means, and apply grounding and bonding provisions. Preparation should include dwelling and non-dwelling calculations.

Conductor questions may involve ampacity tables, terminal-temperature limitations, ambient-temperature corrections, adjustment factors, conductor insulation ratings, parallel conductors, and equipment termination requirements. Selecting a value from an ampacity table may be only one step in determining the correct conductor size.

Motor questions may require several NEC steps. Candidates may need to determine full-load current, branch-circuit conductor size, short-circuit and ground-fault protection, overload protection, controller ratings, disconnecting means, and feeder requirements.

Transformer questions may involve primary and secondary conductor sizing, overcurrent protection, grounding, bonding, installation requirements, and separately derived systems. Ugly's Electrical References can help reinforce transformer ratios, current calculations, and commonly used formulas during preparation.

With 80 questions and four hours available, candidates have an average of three minutes per question. Direct code questions may take less time, while calculations and multi-section research questions may require more. Timed practice helps candidates develop a balanced examination pace.

Open Book Test

The ICC T17-N Journeyman Electrician examination is an open-book test. Candidates may use qualifying references in accordance with current ICC contractor and trades examination policies.

The 2020 National Electrical Code is the primary reference for this exam preparation program. Questions are based on the assigned reference materials, so candidates should study with the correct NEC edition rather than relying on a newer or older code cycle.

Open-book testing still requires strong familiarity with the NEC. Candidates should understand the code’s structure, including Article 100 definitions, the general requirements in Chapters 1 through 4, specialized requirements in Chapters 5 through 7, communications systems in Chapter 8, and calculation tables in Chapter 9.

Practice recognizing the likely article before beginning a search. Service questions commonly lead to Article 230. Grounding and bonding questions frequently involve Article 250. Motors are addressed in Article 430, transformers in Article 450, and generators in Article 445.

Ugly's Electrical References supports preparation involving formulas, conductor properties, voltage drop, grounding, motors, transformers, electrical units, and conversions. It should complement direct NEC study rather than replace familiarity with the code.

During timed practice, read the entire question before opening a reference. Determine whether the question asks for a minimum, maximum, permitted, prohibited, or required condition. Locate the applicable rule, review nearby exceptions, and confirm that the selected answer responds to the exact wording of the question.

State Requirements

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

Electrical contractors and their employees must obtain the appropriate trade licenses before performing regulated electrical work within Jefferson City limits. A journeyman license is an individual trade credential and is separate from the licenses required to operate an electrical contracting business.

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

The City application also requires the applicant to pass an ICC or Prometric Journeyman Electrician examination based on the 2020 National Electrical Code or a newer edition. The minimum passing score is 70 percent, and a copy of the examination result must be submitted.

The T17-N examination is associated with the 2020 NEC code cycle. Jefferson City’s current public licensing page specifically identifies the ICC G17 Journeyman Electrician exam as accepted by the Board. Candidates pursuing a Jefferson City license should use the exam code approved for their individual application.

Passing an ICC examination does not automatically issue a Jefferson City journeyman license. Applicants must complete the local application process and provide the required experience records, examination result, fee, and supporting information.

A journeyman electrician license does not independently authorize the holder to operate an electrical contracting company or obtain permits as an electrical contractor. Separate state, municipal, business, insurance, and contractor licensing requirements may apply.

Jefferson City journeyman licenses must be maintained through the applicable renewal process. Electrical work must comply with the code edition and local requirements enforced by the authority having jurisdiction.
