Module 3: BUILDING ELECTRICAL DESIGN PRINCIPLES

Question 1

 design of an electrical system involves applying the standards written into the building code

Answer 1

Electrical Code

Question 2

 specifies the minimum provisions necessary for protecting people and property from the improper use of electricity and electrical equipment
 applies to both the manufacture and installation of electrical equipment

Answer 2

Electrical Code

Question 3

 used nationally as the basis for safeguarding persons, buildings and its contents from hazards that may arise from the use of electricity

Answer 3

Philippine Electrical Code (PEC)

Question 4

 This Code contains provisions which is necessary for safety and thus is used as basis for the legal enforcement in the installation of electrical system design in the country

Answer 4

Philippine Electrical Code (PEC)

Question 5

 Most municipalities have ordinances (local laws) that require that any person who wishes to engage in the business of installing electrical systems must be licensed (usually by the state or province).

Answer 5

Licensing

Question 6

 Most municipalities require that a permit be issued before any electrical installations may be made on a project.

Answer 6

Permits

Question 7

 show the layout and design of an electrical installation

Answer 7

Electrical construction drawings

Question 8

 will guide the electrical design engineers, inspectors from the office of the local building official, inspectors from the local electric utility, prospective bidders, and other persons who have interests in the project

Answer 8

Location Plan

Question 9

 similar to the architectural layout except that the electrical layout contains the interconnection of the service drop/lateral, service entrance, service equipment, feeder, subfeeder, load center, panelboards, branch circuit, and nomenclature of occupancies

Answer 9

Electrical Layout

Question 10

 help in understanding the electrical plan
 The recommended symbols are shown in Appendix A of the Philippine Electrical Code Part 1 2009. However, other symbols can be used, especially the local symbols which are easily understood in the area.

Answer 10

Legend or Symbol

Question 11

This shows a comprehensive interconnection, size, and rating of the service drop/lateral, service entrance, service equipment, feeder, subfeeders, load centers, and panelboard. This is necessary in the computation of short circuit current and voltage drops.

Question 12

This shows a comprehensive interconnection, size, and rating of the service drop/lateral, service entrance, service equipment, feeder, subfeeders, load centers, and panelboard. This is necessary in the computation of short circuit current and voltage drops.

Answer 12

Single Line or Riser Diagram
