The training is organized around the 2020 National Electrical Code and covers electrical theory, NEC navigation, services, feeders, branch circuits, conductors, wiring methods, grounding, bonding, overcurrent protection, motors, transformers, generators, controls, equipment, calculations, and special electrical installations.

The ICC T17-N examination is associated with NFPA 70, National Electrical Code, 2020 Edition. It evaluates journeyman-level electrical knowledge and the ability to locate, interpret, and apply code requirements in a timed examination environment. Effective preparation requires practical trade knowledge, electrical calculation skills, and an organized method for navigating NEC definitions, articles, tables, exceptions, notes, and cross-references.

Journeyman electrician exam preparation involves more than memorizing isolated code sections. Many examination questions combine several electrical requirements. A conductor-sizing problem may involve a calculated load, continuous-load rules, conductor ampacity, terminal-temperature limitations, correction factors, adjustment factors, overcurrent protection, and an equipment-specific requirement located in another NEC article.

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 continue without spending too much testing time on one problem.

This ICC Journeyman Electrician T17-N exam prep program provides three connected ways to study. The complete online course offers an organized self-paced path through the principal examination subjects. Recorded classes allow students to pause technical explanations, repeat calculations, and revisit code-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, sections, exceptions, or tables.

Major preparation areas include:

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

Wiring methods and materials are 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 when an equipment-specific article modifies or supplements 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 both 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 part of determining the final 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 reinforce transformer ratios, current calculations, and frequently used electrical 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 establish a controlled testing pace and avoid losing too much time on one difficult item.

Open Book Test

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

The 2020 National Electrical Code is the primary reference for this exam preparation program. Candidates should study with the assigned 2020 edition because definitions, article wording, table values, numbering, and installation requirements may differ in earlier or later NEC editions.

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

Practice identifying the likely code location 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.

References brought into the examination must comply with the testing rules for the selected delivery method. Candidates should review applicable requirements concerning approved references, book bindings, tabs, notes, calculators, identification, and examination procedures before test day.

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

State Requirements

The ICC T17-N National Standard Journeyman Electrician examination is a contractor and trades examination that may be used by licensing agencies, employers, apprenticeship organizations, and other authorities to evaluate electrical knowledge. Passing the examination does not automatically create a state or municipal journeyman electrician license.

Electrical licensing requirements vary by state and local jurisdiction. Some states administer statewide electrical licenses, while others allow cities, counties, or regional authorities to establish their own journeyman requirements. A jurisdiction may accept the T17-N examination, require a different ICC examination code, or use another testing provider.

Licensing requirements may include documented electrical experience, apprenticeship hours, classroom education, employer affidavits, professional references, identification, application fees, photographs, background information, continuing education, and periodic renewal.

Candidates should confirm that the T17-N examination and the 2020 NEC code cycle meet the requirements of the authority receiving the score. A jurisdiction may currently enforce a newer NEC edition for field installations while continuing to recognize an examination based on the 2020 NEC, or it may require an exam based on its currently adopted code.

Passing a journeyman examination does not necessarily authorize the holder to operate an electrical contracting business, advertise as an electrical contractor, obtain permits, supervise apprentices, or assume responsibility for contracted work. Separate master electrician, contractor, business, insurance, bond, or qualifying-individual requirements may apply.

Exam preparation and field compliance should be treated as related but separate responsibilities. Candidates should use the 2020 NEC when preparing for the T17-N examination and follow the electrical code edition and local amendments adopted by the authority having jurisdiction when performing regulated electrical work.
