1According to NEC Article 100, what is the definition of a 'dwelling unit'?
A.A single unit providing complete and independent living facilities for one or more persons, including permanent provisions for living, sleeping, cooking, and sanitation
B.Any room with a bed and bathroom
C.A building designed for residential use only
D.Any structure with a kitchen
Explanation: NEC Article 100 defines a dwelling unit as providing complete and independent living facilities including permanent provisions for living, sleeping, cooking, and sanitation. This definition is critical for Minnesota electricians as it determines which NEC dwelling unit requirements apply.
2Per NEC Article 100, what does the term 'identified' mean as used in the NEC?
A.Recognized as suitable for the specific purpose, function, use, environment, or application by a qualified testing laboratory
B.Marked with the manufacturer's name
C.Listed in the NEC index
D.Approved by the local inspector
Explanation: NEC Article 100 defines 'identified' as recognized as suitable for the specific purpose, function, use, environment, or application, as described in the applicable NEC requirement. Minnesota Board of Electricity uses this definition when evaluating equipment suitability.
3Per NEC 110.3(B), what is required regarding instructions included with listed electrical equipment?
A.Listed or labeled equipment must be installed and used in accordance with any instructions included in the listing or labeling
B.Instructions are optional recommendations that do not carry code authority
C.Only the local inspector's interpretation of the instructions applies
D.Instructions only apply to commercial installations
Explanation: NEC 110.3(B) mandates that listed or labeled equipment be installed and used in accordance with any instructions included in the listing or labeling. This makes manufacturer installation instructions enforceable by Minnesota electrical inspectors.
4Per NEC 210.8(A), in a Minnesota dwelling unit, GFCI protection is required for 125-volt receptacles within what distance of a sink?
A.Within 6 feet of the outside edge of the sink
B.Within 3 feet of the sink
C.Within 10 feet of the sink
D.Only directly above the sink
Explanation: NEC 210.8(A)(7) requires GFCI protection for 125-volt, 15- and 20-ampere receptacles within 6 feet of the outside edge of a sink in dwelling units. Minnesota has adopted NEC 2023, which includes this expanded sink proximity requirement.
5Per NEC 210.11(C)(2), what dedicated circuit is required for a dwelling unit bathroom in Minnesota?
A.At least one 20-ampere branch circuit that supplies only bathroom receptacle outlet(s)
B.A 15-ampere circuit shared with bedroom outlets
C.A 20-ampere circuit shared with hallway lights
D.No dedicated bathroom circuit is required
Explanation: NEC 210.11(C)(2) requires at least one 20-ampere branch circuit for bathroom receptacle outlets. This circuit can supply outlets in multiple bathrooms but cannot supply outlets in other rooms. Minnesota Board of Electricity enforces this requirement.
6Per NEC 210.52(D), what is required for outdoor receptacle outlets at a dwelling unit in Minnesota?
A.At least two receptacles must be installed, one at the front and one at the back of the dwelling
B.One outdoor receptacle is sufficient
C.Outdoor receptacles are optional in cold climates
D.Three outdoor receptacles are required minimum
Explanation: NEC 210.52(E) requires at least two outdoor receptacle outlets for one-family dwellings — one at the front and one at the back. Both must have GFCI protection and be readily accessible. Minnesota requires compliance despite the cold climate.
7What is the ampacity of a 10 AWG copper THHN conductor at 30°C per NEC Table 310.16?
A.40 amperes
B.35 amperes
C.30 amperes
D.25 amperes
Explanation: Per NEC Table 310.16, a 10 AWG copper conductor with THHN insulation (90°C column) has an ampacity of 40 amperes at 30°C ambient temperature. Minnesota electricians must know these values for proper circuit sizing.
8Per NEC 240.4(D), what is the maximum overcurrent protection for 10 AWG copper conductors?
A.30 amperes
B.25 amperes
C.35 amperes
D.40 amperes
Explanation: NEC 240.4(D) limits overcurrent protection for 10 AWG copper to 30 amperes. This is a hard limit regardless of the conductor's ampacity at any temperature rating. Minnesota electricians must observe this maximum when sizing circuit protection.
9Per NEC 210.19(A)(1), what is the minimum conductor size for a 20-ampere branch circuit?
A.12 AWG copper
B.14 AWG copper
C.10 AWG copper
D.8 AWG copper
Explanation: NEC 210.19(A)(1) requires branch-circuit conductors to have an ampacity not less than the maximum load to be served. Per NEC 240.4(D), 12 AWG copper is the minimum size that can be protected at 20 amperes. Minnesota installations must use 12 AWG minimum for 20A circuits.
10A Minnesota dwelling has 1,800 sq ft of living space. What is the minimum number of 15-ampere general lighting circuits required?
A.Three circuits (1,800 × 3 VA = 5,400 VA ÷ 1,800 VA per circuit = 3)
B.Two circuits
C.Four circuits
D.Five circuits
Explanation: Calculate: 1,800 sq ft × 3 VA/sq ft = 5,400 VA total lighting load. Each 15A, 120V circuit supplies 1,800 VA (15 × 120). 5,400 ÷ 1,800 = 3 circuits minimum. Minnesota dwelling units must meet this minimum general lighting circuit count.

What NEC edition does Minnesota use for the electrician exam?

Minnesota uses the NEC 2023 edition. The state Board of Electricity adopts each NEC edition through rulemaking. A bound copy of the NEC is typically allowed during the exam.

Is the Minnesota electrician exam administered by PSI?

No. Unlike most states, Minnesota administers its own journeyman electrician exam through the Board of Electricity under the Department of Labor and Industry. You schedule directly through the state, not a third-party testing vendor.

How much apprenticeship is required in Minnesota?

Minnesota requires 8,000 hours of registered electrical apprenticeship under a licensed journeyman or master electrician. The apprenticeship must be registered with the Minnesota Department of Labor and Industry.

Does Minnesota have reciprocity with other states?

Minnesota has limited reciprocity agreements. Contact the Board of Electricity directly to verify if your state license qualifies. Most applicants will need to pass the Minnesota exam regardless of other credentials.
