Tennessee NASCLA Journeyman Electrician Exam Book Package

Prepare for the Tennessee NASCLA Journeyman Electrician examination with a focused collection of electrical code, safety, theory, fire alarm, and field reference materials. The Tennessee NASCLA Journeyman Electrician Exam Book Package brings together the books candidates can use to strengthen National Electrical Code navigation, electrical calculations, workplace safety knowledge, troubleshooting skills, and practical journeyman-level electrical understanding.

The Tennessee Board for Licensing Contractors participates in the NASCLA Accredited Electrical Examination Program and accepts the NASCLA Accredited Examination for Journeyman Electricians. NASCLA's electrical examination program provides a standardized trade examination that can be accepted by participating licensing agencies while each jurisdiction maintains its own licensing, certification, application, and scope-of-work requirements.

This package includes the 2023 National Electrical Code, federal OSHA construction and general-industry regulations, NFPA 70E, Ugly's Electrical References, NFPA 72, and Understanding Electrical Theory for NEC Applications. These references support preparation involving electrical theory, wiring and protection, wiring methods, general code requirements, equipment, workplace safety, troubleshooting, fire alarm systems, and other subjects associated with journeyman electrical work.

Because the NASCLA Journeyman Electrician examination is open book, a strong preparation strategy involves both electrical knowledge and reference navigation. Candidates should become familiar with how each book is organized, understand which reference applies to different types of electrical questions, and practice locating information efficiently while solving exam-style problems.

This book package provides the foundation for that type of preparation. Instead of approaching the examination as a memorization exercise, candidates can build familiarity with the references and learn to move confidently between electrical code requirements, formulas, safety standards, theory concepts, and specialty-system information.

Exam Details

The NASCLA Accredited Examination for Journeyman Electricians is designed around the competency expected of an individual performing electrical installation, maintenance, and repair work in accordance with applicable standards and codes. NASCLA developed the examination through a national occupational analysis involving electrical subject matter experts and electricians from multiple jurisdictions.

The current NASCLA Journeyman Electrician examination contains 100 scored questions. Candidates must achieve a minimum passing score of 70. The current candidate information published for the examination allows 300 minutes for completion.

In addition to the scored questions, NASCLA may administer non-scored experimental questions. These questions are used for future examination development and are not included when calculating the candidate's final examination score.

The Journeyman Electrician examination content outline covers the following major subject areas:

• Interpreting Plans and Specifications
• Basic Electrical Safety
• Electrical Theory and Principles
• Testing and Troubleshooting
• General Code Requirements
• Wiring and Protection
• Wiring Methods and Materials
• Equipment for General Use
• Special Occupancies and Special Equipment
• Special Conditions and Communication Systems

The examination places substantial emphasis on code-based electrical work. Candidates should be prepared to locate and apply requirements for branch circuits, feeders, services, conductor protection, grounding and bonding, wiring methods, equipment, special installations, and other National Electrical Code subjects.

Electrical theory, safety, plans, troubleshooting, and specialty systems remain important parts of preparation. A candidate who concentrates only on NEC lookup may leave significant areas of the examination insufficiently reviewed.

NASCLA examination applications are handled through the NASCLA National Examination Database. Once an application is approved, candidates receive examination scheduling information for the NASCLA testing program. NASCLA currently provides approved candidates with up to three examination attempts during the one-year eligibility period associated with an approved application.

Open Book Test

The NASCLA Accredited Journeyman Electrician examination is an open book test. Candidates may use authorized reference materials in accordance with NASCLA and testing-center rules.

Open-book testing does not remove the need for preparation. Candidates still need to identify the electrical concept involved, select the appropriate reference, locate the correct section or table, interpret the information, and apply it accurately within the available testing time.

The 2023 National Electrical Code should become one of the most familiar references in your library. Practice using the NEC index, Article 100 definitions, chapters, articles, tables, informational notes, and cross-references. Learn where commonly tested subjects are located rather than attempting to memorize every code number.

NASCLA testing rules permit qualifying reference materials to be highlighted, underlined, and indexed. Permanent tabs may be used under the published testing rules. Temporary tabs such as Post-it notes are not allowed. References must otherwise remain unmarked and cannot contain additional loose or attached papers.

The reference books are not supplied at the examination center, so candidates using permitted books must bring their own approved materials. Preparing with the same references before testing helps build familiarity with each book's organization and reduces the need for random searching.

A useful practice technique is to read a question, identify the topic before opening a book, choose the reference most likely to contain the answer, and then locate the applicable information. Repeating that process develops both technical knowledge and practical reference-navigation skills.

Licensing Steps

Tennessee's electrical licensing structure includes state contractor licensing, the Limited Licensed Electrician program, and local electrical licensing requirements. Tennessee does not treat passing the NASCLA Journeyman Electrician examination by itself as permission to perform unrestricted electrical contracting work throughout the state.

1. Identify the Tennessee license or local credential required for your work. Determine whether the work falls under Tennessee contractor licensing, Limited Licensed Electrician requirements, or a municipality's local electrical licensing rules.
2. Review the applicable licensing authority's requirements. The Tennessee Board for Licensing Contractors regulates contractor licenses and the state Limited Licensed Electrician program, while local jurisdictions may impose their own requirements.
3. Prepare for the NASCLA Journeyman Electrician examination. Study the 2023 NEC, electrical theory, workplace safety, wiring methods, troubleshooting, equipment, calculations, and specialty systems.
4. Apply for the NASCLA examination. Complete the NASCLA Accredited Examination application process through the National Examination Database.
5. Schedule and take the examination. Follow the NASCLA testing instructions and examination-center rules for identification, references, permanent tabs, calculators, and prohibited materials.
6. Pass the NASCLA Journeyman Electrician examination. After passing, the examination result is recorded in NASCLA's National Examination Database.
7. Submit the examination result when applicable. NASCLA transcripts can be transmitted electronically to participating agencies that accept the examination.
8. Complete the applicable Tennessee or local licensing process. Meet all additional application, examination, financial, business, permit, or local requirements associated with the credential needed for the work you intend to perform.

State Requirements

The Tennessee Board for Licensing Contractors is the state agency responsible for contractor licenses and the Limited Licensed Electrician program. NASCLA currently lists the Tennessee Board for Licensing Contractors as an agency that accepts the Journeyman Electrician examination.

Tennessee's electrical licensing structure is different from states that issue a single statewide Journeyman Electrician license covering electrical work everywhere in the state. Candidates should distinguish between the NASCLA Journeyman Electrician examination and the particular Tennessee credential required for the work they plan to perform.

For larger contracting projects, Tennessee contractor licensing requirements may apply. A Tennessee contractor license is generally required before bidding, offering to perform, or contracting for projects of $25,000 or more. Electrical subcontractors are also subject to contractor licensing requirements when the electrical portion of the project meets the applicable threshold.

Tennessee's full electrical contractor classification is designated CE – Electrical Contracting. The CE classification covers electrical work for buildings and structures and requires a trade examination. Tennessee contractor applicants are also required to complete the state's Business and Law examination.

The Limited Licensed Electrician, or LLE, is a separate Tennessee credential. The LLE applies in municipalities that use the Tennessee Division of Fire Prevention for permits or inspections and covers qualifying electrical work costing less than $25,000 per project. Local governments may maintain their own licensing requirements, so the applicable local authority determines what credential is required in a particular area.

For this reason, a NASCLA Journeyman Electrician examination result should not be confused with a Tennessee LLE license, a Tennessee CE contractor license, or a local journeyman credential. These are separate regulatory pathways.

Tennessee also requires contractors to hold the appropriate classification before performing work that falls within state contractor licensing requirements. The classification determines the type of contracting work the license authorizes, while the contractor license also carries a monetary limit.

The Tennessee Board for Licensing Contractors changed its trade examination provider in 2026. Beginning July 1, 2026, Prov serves as the Board's new trade exam provider for Tennessee state contractor examinations. That state-provider change is separate from the national NASCLA Accredited Examination process.

Candidates planning to use NASCLA results in Tennessee should match the examination to the specific licensing or credentialing pathway they are pursuing and complete all remaining requirements imposed by the appropriate state or local authority.

Ugly's Electrical References provides another useful resource for calculations, formulas, conversions, and practical field information. Practice recognizing which formula applies to a particular situation instead of simply memorizing isolated equations.

Safety preparation should include OSHA 29 CFR Part 1926, OSHA 29 CFR 1910, and NFPA 70E. These references address construction safety, general workplace requirements, and electrical-specific safe-work practices. Understanding the differences among these sources can make safety-related reference navigation more efficient.

NFPA 72 supports preparation involving fire alarm and signaling systems. Candidates should become familiar with how fire alarm requirements are organized and where to locate information involving initiating devices, notification, system functions, and related electrical requirements.

Testing and troubleshooting should also receive regular study attention. Review voltage, resistance, current, continuity, circuit behavior, equipment operation, and the logical use of electrical test instruments. Journeyman-level questions may require practical reasoning in addition to code lookup.

Plans and specifications are another important part of electrical exam preparation. Practice interpreting symbols, circuits, equipment locations, and installation information shown on electrical drawings. Understanding how design information translates into field installation supports both exam preparation and practical trade knowledge.

Use the reference package actively. When working a practice question, identify the topic first, determine which reference applies, locate the relevant information, and then solve or confirm the answer. This routine builds familiarity with the books while reinforcing the electrical principles behind the question.
