ELECTRICIAN EXAM COMPREHENSIVE
PRACTICE TEST 2026
Section 1: General Electrical Theory & Code (NEC 2020)
1. According to the NEC, what is the minimum clearance for service-drop conductors over a residential
driveway?
A) 10 ft
B) 12 ft
C) 15 ft
D) 18 ft
Answer: B) 12 ft
Rationale: NEC 230.24(B) requires a clearance of 12 ft above residential driveways and commercial areas
subject to truck traffic typically requires higher, but residential is 12 ft.
2. In a dwelling unit, the required lighting outlet in a hallway shall be located at the hallway’s ______.
A) Center
B) Any point
C) Intersection with stairways
D) Entry point
Answer: C) Intersection with stairways
*Rationale: NEC 210.70(A)(2)(a) requires a wall switch-controlled lighting outlet at the point of entry to
hallways, stairways, and attached garages.*
3. What is the ampacity of a 1 AWG THHN copper conductor at 75°C?
A) 110 A
B) 130 A
C) 150 A
D) 175 A
Answer: B) 130 A
,Rationale: NEC Table 310.15(B)(16) lists 1 AWG THHN at 90°C (150A) but if terminated at equipment
rated for 75°C (common in panels), you must use the 75°C column, which is 130A.
4. A continuous load is defined as a load where the maximum current is expected to continue for
______ or more.
A) 1 hour
B) 2 hours
C) 3 hours
D) 4 hours
Answer: C) 3 hours
Rationale: NEC Article 100 defines a continuous load as one where the maximum current is expected to
continue for 3 hours or more.
5. The "BC" in "AFCI" stands for ______.
A) Branch Circuit
B) Breaker Circuit
C) Basic Control
D) Building Code
Answer: A) Branch Circuit
*Rationale: AFCI stands for Arc-Fault Circuit-Interrupter. NEC 210.12 requires AFCI protection for branch
circuits in dwelling units.*
6. When using the standard method of load calculation for a 2,500 sq ft dwelling, the general lighting
load is calculated at ______ per sq ft.
A) 2 VA
B) 3 VA
C) 4 VA
D) 5 VA
Answer: B) 3 VA
Rationale: NEC Table 220.12 specifies 3 VA per square foot for dwelling units for general lighting and
receptacles.
7. What is the maximum number of 12 AWG THHN conductors permitted in a 3/4-inch EMT conduit?
A) 9
B) 12
C) 16
D) 20
Answer: C) 16
*Rationale: NEC Chapter 9, Table 1, and Table 4 for EMT. 3/4" EMT has a 40% fill area of 0.213 in². 12
AWG THHN has an area of 0.0133 in². 0..0133 = 16.0.*
, 8. According to NEC 300.4, where a nonmetallic sheathed cable (Romex) passes through a metal stud,
it must be protected by a ______.
A) Plastic grommet
B) Metal bushing
C) Nail plate
D) Listed bushing or grommet
Answer: D) Listed bushing or grommet
Rationale: NEC 300.4(B)(1) requires a listed bushing or grommet to protect cables through metal studs or
plates to prevent abrasion from sharp edges.
9. A grounding electrode conductor for a 400-amp service shall be sized according to NEC Table
______.
A) 250.66
B) 310.16
C) 250.122
D) 310.12
Answer: A) 250.66
Rationale: NEC Table 250.66 is used for sizing grounding electrode conductors based on the size of the
largest ungrounded service entrance conductor.
10. The "T" in "THHN" wire stands for ______.
A) Thermoplastic
B) Temperature
C) Twisted
D) Tinned
Answer: A) Thermoplastic
Rationale: THHN stands for Thermoplastic High Heat-resistant Nylon-coated.
Section 2: NYC Local Laws & Amendments (Administrative Code)
11. NYC Local Law 58 of 2009 requires the installation of ______ in all hotel rooms and common
areas?
A) Smoke detectors
B) Carbon monoxide alarms
C) Arc-fault breakers
D) Sprinkler systems
Answer: B) Carbon monoxide alarms
Rationale: Local Law 58 (amended) mandates CO alarms in hotels, lodging houses, and multiple
dwellings with combustion appliances or attached garages.
