MI Journeyman Electrician study guide
MI Journeyman Electrician · Work through your exam, one topic at a time.
The Michigan Journeyman Electrician credential is a skilled-trades license administered through the Michigan Department of Licensing and Regulatory Affairs (LARA) and its Bureau of Construction Codes. Applications, renewals, license lookups, and complaints are handled through LARA's online licensing portals rather than through a separate electrical board website. The license is the standard stepping stone for electricians who have completed their apprenticeship hours and want to work unsupervised on electrical installations, and it is commonly the prerequisite candidates hold before pursuing a master electrician license or contractor registration. The examination is a code-based, closed-book-style knowledge test covering the full span of electrical installation work: general electrical knowledge and code administration; services, feeders, and branch circuits; wiring methods, materials, and raceways; equipment, devices, and utilization equipment; and grounding, bonding, overcurrent protection, and special occupancies. The MI Journeyman Electrician study guide has 5 sections and about 1,590 words.
01General Electrical Knowledge and Code Administration
The Michigan journeyman exam tests both electrical knowledge and the administrative rules that govern electrical work. Start with NEC Article 90 (scope) and Article 100 (definitions); nearly every calculation question depends on a defined term such as service point, feeder, branch circuit, continuous load, or qualified person.
301 words, about 2 min02Services, Feeders, and Branch Circuits
This domain ties load calculation to conductor and overcurrent sizing. Article 220 provides standard and optional calculation methods for dwellings and other occupancies.
344 words, about 2 min03Wiring Methods, Materials, and Raceways
Chapter 3 is the heart of this domain. Article 300 gives general requirements for wiring methods, including protection from physical damage, conductor identification, and support.
327 words, about 2 min04Equipment, Devices, and Utilization Equipment
This domain covers how equipment is selected, rated, connected, and protected. Key articles include 404 (switches), 406 (receptacles), 408 (panelboards), 410 (luminaires), 422 (appliances), 424 (fixed electric heating), 430 (motors), 440 (air conditioning and refrigeration), and 450 (transformers).
315 words, about 2 min05Grounding, Bonding, Overcurrent Protection, and Special Occupancies
Article 250 distinguishes the grounded conductor (neutral), the equipment grounding conductor (EGC), the grounding electrode conductor (GEC), and bonding jumpers. Service equipment must have a main bonding jumper and a grounded-conductor-to-grounding-electrode connection; downstream panels must keep neutral and ground separate except where specifically permitted.
