EU1- MODULE 3: BUILDING ELECTRICAL DESIGN other symbols can be used, especially the
PRINCIPLES local symbols which are easily understood in
the area.
ELECTRICAL CODES, LICENSES AND PERMITS
ELECTRICAL CODE – an electrical code specifies the
minimum provisions necessary for protecting people
and property from the improper use of electricity and
electrical equipment.
- design of an electrical system involves
applying the standards written into the
building code.
PHILIPPINE ELECTRICAL CODE (PEC)
- National basis for safeguarding persons,
buildings and its contents from hazards that
may arise from the use of electricity.
LICENSING – municipalities have ordinances (local
laws) that require license for people to engage in the
business of installing electrical systems.
PERMITS – are required to be issued before any
electrical installations may be made on a project.
ELECTRICAL CONSTRUCTION DRAWINGS
ELECTRICAL CONSTRUCTION DRAWINGS – show the
layout and design of an electrical installation.
REQUIRED CONSTRUCTION DRAWINGS & DETAILS:
1. Complete plans and specifications of all
electrical work
2. Labeling criteria of all electrical equipment
3. Lighting floor plan(s) including electrical
circuits indicating conduit and wiring sizes
4. Power floor plans including electrical circuits
indicating conduit and wiring sizes,
equipment, and disconnect switches
5. Exit sign/means of egress lighting location
and power supply
6. Panelboard schedule
7. Lighting fixture schedule
8. Symbol schedule and diagrams
REVIEW OF THE DESIGN REQUIREMENTS
LOCATION PLAN – this will guide the electrical design
engineers, inspectors from the office of the local
building official, inspectors …, and other persons who
have interests in the project.
ELECTRICAL LAYOUT – this layout Is similar to the
architectural layout except that the electrical layout
contains the interconnection of the service
drop/lateral, service entrance, service eq., feeder …
LEGEND OR SYMBOL – help in understanding the
electrical plan.
- The recommended symbols are shown in
Appendix A of the PEC Part 1 2009. However,
