Idaho Master Electrician Exam Prep - Live Virtual + Self Study Training

Prepare for the Idaho Master 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 2023 National Electrical Code and covers advanced electrical theory, NEC navigation, wiring and protection, wiring methods and materials, equipment for general use, special occupancies, special equipment, special conditions, communication systems, electrical calculations, grounding, bonding, motors, transformers, generators, services, feeders, and branch circuits.

The Idaho Master Electrician exam evaluates the advanced electrical knowledge expected of an experienced journeyman pursuing master-level licensure. Candidates must be prepared to research code requirements efficiently, complete multi-step calculations, evaluate complex installations, and apply general and specialized NEC provisions within a timed examination environment.

Master electrician preparation involves more than reviewing familiar journeyman topics. The examination expects candidates to work accurately across multiple code chapters and recognize how requirements interact. A single question may involve calculated loads, conductor ampacity, terminal-temperature limitations, correction and adjustment factors, overcurrent protection, grounding, bonding, equipment ratings, and a specialized rule located in another NEC article.

Field experience provides an essential foundation, but a timed open-book examination also requires efficient reference navigation. Candidates should be able to identify the subject being tested, choose the most likely NEC article or table, locate the controlling requirement, review nearby exceptions, complete the calculation, and confirm that the selected answer applies to the exact conditions in the question.

This Idaho Master Electrician exam prep program provides three connected ways to study. The complete online course offers a structured self-paced path through the major examination categories. Recorded classes allow students to pause technical explanations, repeat advanced calculations, and revisit NEC navigation demonstrations. Live virtual classes provide scheduled instructor-led training organized around the reference books and electrical subjects included with this product.

The training covers the following references:

• National Electrical Code, NEC, 2023
• Ugly's Electrical References
• 2023 Ferm's Fast Finder Index
• 2023 Key Word Index by Tom Henry

State Requirements

Idaho regulates master electrician licensing through the Idaho Electrical Board and the Division of Occupational and Professional Licenses. The master electrician credential is an individual electrical license issued to applicants who satisfy the required journeyman-license history, examination, application, and supporting-document requirements.

An applicant seeking initial Idaho Master Electrician licensure must have held an active electrical journeyman license for at least four years. The journeyman credential must remain active for the qualifying period used to establish eligibility.

Idaho’s current licensing instructions direct initial master applicants to pass the applicable NASCLA examination before submitting the license application to DOPL. Examination scheduling is completed through PSI.

The current Idaho examination bulletin lists the ID Master Electrician Exam as a 100-question test with a minimum passing score of 75 and a time allowance of 270 minutes.

Passing the examination does not automatically issue the Idaho Master Electrician license. Applicants must also submit the required application and documentation to DOPL and receive approval from the licensing authority.

Applicants already licensed as master electricians in another jurisdiction may use the reciprocal application pathway when applicable. License verification must be completed by the issuing jurisdiction rather than replaced by a copy of the applicant’s license.

An Idaho Master Electrician license is an individual credential and is not the same as an electrical contractor license. Operating an electrical contracting business, advertising contracting services, obtaining permits as a contractor, or assuming responsibility for contracted electrical work may require a separate electrical contractor license and related business requirements.

Electrical work performed in Idaho must comply with the code edition, state rules, and amendments enforced by the authority having jurisdiction. Candidates should use the 2023 NEC for this preparation program and follow the currently adopted requirements when performing field installations.
