Electrical Wiring Plan
This is a proposed electrical plan
to be installed for a house,
building or other related structure.
This is a technical representation
for the electrical methods to be
applied, the supplies and
materials to be used, the
comprehensive computation of
loads, determining the safe size of
wires, conduit and circuit breaker.
Parts of Electrical Wiring Plan
1. Title Block or Name Plate This is located at the
bottom portion of an Electrical Wiring Plan
that shows the following details:
2. A. The name of the company contracted for the
project
3. B. Proposed installation or project;

commissioned by the owner for the project;
5. E. Title of sheet, sheet number and scale which
the floor plan is drawn; and F. Draftsman’s
initial and dates when the electrical wiring plan
was drawn.
2. Floor Plan It is the sketch that shows the
top view of the house, building or other
related structure. It shows the electrical
layout plan where the lighting and power
outlets are located. This indicates the
following details:

symbols shown in the floor plan
and riser diagram are interpreted
in the Legend. Electrical symbols
allows the Electrical Engineers,
Electricians and owner to
interpret the electrical
installations, equipment, fixtures
and electrical connections made

structure, bordering areas and
well known streets; and
B. B. Electrical power company
service pole
4. Riser Diagram This shows a line diagram of
the main disconnecting means, electric service
meter and service entrance; and details
following:
