1. What is the primary purpose of an electrical plan?
A. To show only the architectural appearance of a building
B. To provide details for installing and inspecting electrical
systems
C. To calculate construction labor costs only
D. To replace electrical code requirements
Correct Answer: B. To provide details for installing and
inspecting electrical systems
Rationale: Electrical plans communicate the design, layout, and
requirements of electrical installations so contractors and
inspectors can verify compliance with applicable codes.
2. Which document is typically used by an electrical plans
examiner to verify compliance?
A. Plumbing drawings
B. Building color schedule
C. Electrical code requirements
D. Landscaping plans
,Correct Answer: C. Electrical code requirements
Rationale: Plans examiners use electrical codes, such as the
National Electrical Code (NEC), to determine whether designs
meet safety requirements.
3. What does NEC stand for?
A. National Engineering Calculation
B. National Electrical Code
C. National Energy Construction
D. New Electrical Certification
Correct Answer: B. National Electrical Code
Rationale: The NEC provides minimum safety standards for
electrical installations.
4. On electrical drawings, a single-line diagram is used to
show:
A. Exact wire colors only
B. Electrical system relationships using simplified symbols
C. Building elevations
D. Lighting fixture designs only
Correct Answer: B. Electrical system relationships using
simplified symbols
,Rationale: Single-line diagrams simplify complex electrical
systems by showing connections and major components.
5. Which symbol is commonly used to represent a lighting
fixture on electrical plans?
A. A lighting symbol identified in the legend
B. A plumbing symbol

B. Meaning of symbols and abbreviations
C. Employee schedules
D. Material prices
Correct Answer: B. Meaning of symbols and abbreviations
Rationale: The legend helps interpret electrical drawings
accurately.
7. What is the purpose of a load calculation?
, A. Determine electrical demand requirements
B. Determine paint colors
C. Determine building height
D. Determine plumbing pressure
Correct Answer: A. Determine electrical demand requirements
Rationale: Load calculations ensure electrical equipment and
conductors are properly sized.
8. A feeder conductor supplies power from the:
A. Switch to the light fixture
B. Service equipment to branch circuits or panels
C. Receptacle to appliance
D. Battery to charger only
Correct Answer: B. Service equipment to branch circuits or
panels
Rationale: Feeders distribute power from the service or main
equipment to downstream distribution points.
9. Branch circuits provide power to:
A. Individual loads and utilization equipment
B. Utility transformers only
C. Transmission lines
D. Generator fuel systems
