Electrical Wiring Commercial (18th Edition) — Study Questions
Chapter 1: Commercial Building Plans and Specifications
,1. What is the primary purpose of commercial building plans?
A. To estimate worker salaries
B. To provide detailed instructions for constructing and wiring a building
C. To list all construction materials suppliers
D. To determine real estate value
Correct Answer: B
Rationale:
Commercial building plans provide a visual and technical representation of how a building will be
constructed, including electrical layouts, structural components, and mechanical systems.
Electricians rely on these plans to understand where to install wiring, devices, and equipment safely
and accurately.
2. Which document provides detailed written requirements for materials and installation
methods?
A. Blueprints
B. Specifications
C. Panel schedules
D. Elevation drawings
Correct Answer: B
Rationale:
Specifications accompany drawings and describe materials, installation standards, quality
requirements, and construction procedures. While drawings show the layout, specifications explain
how the work must be performed.
3. What does the term “blueprint” traditionally refer to?
A. A contract agreement
B. A printed construction drawing used to guide building work
C. A building permit
D. A cost estimation sheet
Correct Answer: B
Rationale:
The term blueprint historically referred to reproduction drawings with white lines on a blue
background. Today, it broadly refers to construction drawings that guide builders and electricians in
installing building systems.
4. What is the first page of most construction drawing sets called?
, A. Legend page
B. Title sheet
C. Electrical schedule
D. Elevation sheet
Correct Answer: B
Rationale:
The title sheet introduces the drawing set. It usually contains the project name, location, designer,
date, drawing index, and general information.
5. What is the purpose of a drawing legend?
A. To list electrical contractors
B. To explain symbols used on the drawings
C. To display material prices
D. To show panelboard locations
Correct Answer: B
Rationale:
The legend explains graphical symbols used in drawings, such as outlets, switches, lighting fixtures,
and electrical devices. This ensures anyone reading the plans interprets the symbols correctly.
6. What information is usually included in the title block of a drawing?
A. Wiring methods only
B. Project details, drawing number, date, and designer
C. Electrical code references only
D. Building permits
Correct Answer: B
Rationale:
The title block contains essential project information, including project title, drawing number, date,
scale, and responsible designer or engineer.
7. Who typically prepares the electrical drawings for a commercial building?
A. Architect only
B. Electrical engineer or electrical designer
C. Building owner
D. City inspector
Correct Answer: B
Rationale:
Electrical systems in commercial buildings are usually designed by electrical engineers or electrical
designers to ensure code compliance, efficiency, and safety.
