The Michigan journeyman electrician exam requires 70% to pass across 80 NEC-based questions in 4 hours. Michigan uses the NEC 2023 edition and does not offer reciprocity — you must pass the MI exam regardless of other state licenses. The exam is open-book (bound NEC copy allowed). LARA requires 8,000 hours of apprenticeship or equivalent experience.

1According to NEC Article 100, what is the definition of a 'branch circuit'?
A.The circuit conductors between the final overcurrent device protecting the circuit and the outlet(s)
B.Any circuit that extends from the service entrance to the first junction box
C.A circuit that provides power exclusively to lighting fixtures
D.The wiring between the utility transformer and the main panel
Explanation: NEC Article 100 defines a branch circuit as 'the circuit conductors between the final overcurrent device protecting the circuit and the outlet(s).' This definition is fundamental for Michigan electricians as it determines how circuits are sized, protected, and installed under LARA regulations.
2Per NEC Article 100, what does 'readily accessible' mean?
A.Capable of being reached quickly for operation, renewal, or inspections without climbing or removing obstacles
B.Accessible by using a ladder or removing a panel cover
C.Any equipment that is visible from the floor
D.Equipment installed within arm's reach of the ground
Explanation: NEC Article 100 defines 'readily accessible' as 'capable of being reached quickly for operation, renewal, or inspections without requiring those to whom ready access is requisite to climb over or remove obstacles, or to resort to portable ladders, etc.' Michigan LARA inspectors verify this for disconnects and overcurrent devices.
3What is the standard voltage used for residential branch circuit calculations in Michigan per NEC 220.5?
A.120V or 240V nominal
B.115V or 230V
C.110V or 220V
D.125V or 250V
Explanation: NEC 220.5(A) requires that branch-circuit loads be calculated using the nominal system voltage: 120V, 120/240V, or 208Y/120V. Michigan residential installations typically use 120/240V single-phase. Using actual measured voltage instead of nominal voltage is a common exam mistake.
4Per NEC 210.8(A), GFCI protection is required for 125-volt, 15- and 20-ampere receptacles in which of the following dwelling unit locations?
A.Bathrooms, kitchens, garages, outdoors, crawl spaces, and basements
B.Bathrooms, bedrooms, and living rooms
C.Only bathrooms and kitchens
D.Bathrooms and garages only
Explanation: NEC 210.8(A) requires GFCI protection for all 125-volt, 15- and 20-ampere receptacles in dwelling unit bathrooms, garages, outdoors, crawl spaces, basements (finished or unfinished), kitchens, laundry areas, and within 6 feet of sinks. Michigan enforces NEC 2023 which expanded these requirements.
5What is the minimum number of 20-ampere small-appliance branch circuits required in a dwelling unit kitchen per NEC 210.11(C)(1)?
A.Two
B.One
C.Three
D.Four
Explanation: NEC 210.11(C)(1) requires a minimum of two 20-ampere small-appliance branch circuits to serve receptacle outlets in the kitchen, pantry, breakfast room, dining room, or similar area. These circuits must not supply any other outlets in Michigan dwelling units.
6Per NEC 210.12, AFCI protection is required for branch circuits supplying outlets in which dwelling unit areas?
A.Kitchens, family rooms, dining rooms, living rooms, parlors, libraries, dens, bedrooms, sunrooms, recreation rooms, closets, hallways, laundry areas, and similar rooms
B.Only bedrooms
C.Bedrooms, living rooms, and kitchens only
D.All areas of the dwelling unit including bathrooms and garages
Explanation: NEC 210.12(A) requires AFCI protection for all 120-volt, 15- and 20-ampere branch circuits supplying outlets in virtually all habitable dwelling unit areas. The NEC 2023 edition adopted by Michigan includes kitchens, laundry areas, and other spaces that were added in recent code cycles.
7What is the maximum continuous load on a 20-ampere branch circuit per NEC 210.20(A)?
A.16 amperes
B.20 amperes
C.18 amperes
D.15 amperes
Explanation: NEC 210.20(A) requires that the branch-circuit overcurrent device rating not be less than the noncontinuous load plus 125% of the continuous load. For a 20A circuit, the maximum continuous load is 20A × 80% = 16A. Michigan inspectors verify this for commercial lighting circuits.
8Per NEC 210.52(A), what is the maximum distance between receptacle outlets along a wall in a dwelling unit?
A.12 feet (so no point along the wall is more than 6 feet from a receptacle)
B.8 feet between receptacles
C.10 feet between receptacles
D.6 feet between receptacles
Explanation: NEC 210.52(A)(1) requires receptacles to be installed so that no point along the floor line of any wall space is more than 6 feet from a receptacle outlet. This effectively means receptacles must be spaced no more than 12 feet apart. Michigan LARA follows this standard for all dwelling unit inspections.
9What is the ampacity of a 12 AWG copper THHN conductor at 30°C ambient temperature per NEC Table 310.16?
A.30 amperes
B.25 amperes
C.20 amperes
D.35 amperes
Explanation: Per NEC Table 310.16, a 12 AWG copper conductor with THHN insulation (rated 90°C) has an ampacity of 30 amperes at 30°C ambient temperature. However, when used on a 20-ampere circuit, the conductor is protected by the 20A overcurrent device per NEC 240.4(D). Michigan exams test this distinction.
10Per NEC 240.4(D), what is the maximum overcurrent protection for 14 AWG copper conductors?
A.15 amperes
B.20 amperes
C.25 amperes
D.10 amperes
Explanation: NEC 240.4(D) limits overcurrent protection for 14 AWG copper conductors to 15 amperes. This is a hard limit regardless of the conductor's ampacity at any temperature rating. Michigan LARA inspections enforce this strictly.
