ICC Journeyman Electrician - G17-N Exam Prep - Live Virtual + Self Study Training

Prepare for the ICC G17-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 covering electrical theory, National Electrical Code navigation, electrical calculations, services, feeders, branch circuits, wiring methods, grounding, bonding, motors, transformers, generators, controls, equipment, and special electrical installations.

The ICC G17-N examination measures the knowledge and code-navigation skills expected of a journeyman electrician. It is based on NFPA 70, National Electrical Code, 2017 Edition, and requires candidates to locate, interpret, and apply electrical requirements within a timed, open-book testing environment.

Journeyman electrician preparation involves more than memorizing isolated NEC sections. Candidates must understand how general requirements, specialized articles, tables, exceptions, definitions, equipment rules, and calculations work together. A single question may involve conductor ampacity, terminal-temperature limitations, overcurrent protection, grounding, equipment requirements, and an exception found in another code section.

Practical electrical experience provides an important foundation, but the examination also tests the ability to research code provisions efficiently. Candidates should be able to identify the subject of a question, choose the most likely NEC article or table, complete the required calculation, review applicable exceptions, and select the best answer without losing valuable testing time.

This ICC Journeyman Electrician G17-N 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. Live virtual classes provide scheduled instructor-led training organized around the reference books and electrical topics included with the product.

The training covers the following references:

• NFPA 70 - National Electrical Code, 2017 Edition
• Ugly's Electrical References

The 2017 National Electrical Code is the primary examination reference. It supports preparation involving electrical definitions, general installation requirements, wiring and protection, wiring methods and materials, equipment for general use, special occupancies, special equipment, special conditions, communications systems, and calculation tables.

Ugly's Electrical References complements NEC preparation by providing compact access to formulas, conductor properties, electrical units, voltage-drop information, grounding concepts, motor data, transformer information, conversions, and commonly used field calculations.

Exam Details

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

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

The published examination outline is divided into the following content areas:

• General Knowledge: 6 percent
• Services and Service Equipment: 11 percent
• Feeders: 4 percent
• Branch Circuits and Conductors: 19 percent
• Wiring Methods and Materials: 26 percent
• Equipment and Devices: 13 percent
• Control Devices: 4 percent
• Motors and Generators: 6 percent
• Special Occupancies, Equipment, and Conditions: 11 percent

Wiring methods and materials represent the largest portion of the examination. Candidates should be prepared to work with raceways, cables, conductors, boxes, fittings, conductor support, physical protection, wet and damp locations, permitted uses, prohibited uses, and installation requirements.

Branch circuits and conductors are another major examination area. Questions may involve connected loads, continuous loads, conductor sizing, required outlets, receptacle circuits, lighting circuits, overcurrent protection, conductor ampacity, insulation ratings, and equipment requirements.

Services and service equipment may involve service conductors, service equipment, disconnecting means, calculated loads, grounding, bonding, available equipment ratings, and overcurrent protection. Candidates should practice following a calculation from the connected load through demand factors and final conductor selection.

Equipment and device questions may address appliances, luminaires, heating equipment, transformers, panelboards, switchboards, disconnects, receptacles, switches, and other utilization equipment. Candidates must be able to apply both general NEC rules and equipment-specific articles.

Control-device questions may include switches, relays, contactors, starters, disconnects, controllers, and control circuits. Preparation should connect device operation with applicable installation, rating, protection, and accessibility requirements.

Motor and generator questions may require several code steps. A motor problem may involve full-load current, conductor sizing, short-circuit and ground-fault protection, overload protection, controllers, disconnecting means, and feeder calculations. Generator questions may involve conductors, overcurrent protection, transfer equipment, grounding, and standby-system requirements.

Special occupancies, equipment, and conditions may include hazardous locations, healthcare facilities, places of assembly, agricultural buildings, marinas, emergency systems, legally required standby systems, optional standby systems, renewable-energy equipment, and other specialized installations.

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-step research questions may require more. Timed practice helps candidates maintain a steady pace and avoid spending too long on one item.

Open Book Test

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

The 2017 National Electrical Code is the principal approved reference for the examination. Ugly's Electrical References may also be used as a supporting reference under the examination outline. Questions are based on the listed examination references, so preparation should remain centered on the assigned NEC edition.

Open-book testing still requires strong familiarity with the code. Candidates should understand the NEC’s organization, definitions, article structure, tables, exceptions, cross-references, and index before entering the testing environment.

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. Service questions commonly lead to Article 230. Grounding and bonding questions generally 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, motors, transformers, grounding, conversions, and common electrical data. It should complement NEC preparation rather than replace direct familiarity with the code.

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

State Requirements

The ICC G17-N National Standard Journeyman Electrician examination is a national contractor and trades examination. Passing the exam does not automatically create a statewide or municipal electrical license.

States, counties, cities, employers, unions, and other authorities may use ICC examination results differently. Some jurisdictions accept the exam as part of a journeyman electrician application, while others require a different ICC exam code, a different NEC edition, or an examination administered through another testing program.

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

Candidates should confirm that the G17-N examination and the 2017 NEC code cycle satisfy the requirements of the authority receiving the score. A jurisdiction may currently enforce a newer NEC edition or require an examination based on a more recent code cycle.

Passing the examination also does not automatically authorize the holder to operate an electrical contracting business, obtain permits, supervise apprentices, or perform electrical work in every jurisdiction. Those activities may require additional contractor, master electrician, business, or municipal credentials.

Exam preparation and field compliance should be treated as related but separate responsibilities. Use the 2017 NEC when preparing for the G17-N examination, and use the code edition and amendments adopted by the authority having jurisdiction when performing electrical work.
