is the process of planning and designing an electrical system for a construction project. This includes the layout and design of al electrical components including wiring, fixtures, and equipment.

Electrical Design

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

Philippine Electrical Code (PEC)

establishes safety processes that use policies, procedures, and program controls to reduce the risk associated with the use of electricity to an acceptable level.

NFPA 70E

shows the plan and function for an electrical circuit, but is not concerned with the physical layout of the wires.

Schematic Diagram

show how the wires are connected and where they should located in the actual device, as well as the physical connections between all the components

Wiring Diagram

are specialized schematics commonly used to document industrial control logic systems.

Ladder Diagram

are generally accepted sets of rules that tell you what you need to do.

Codes

provide the "how to" of executing codes.

Standards

unlike codes or standards, outline the requirements of a specific task or project.

Specifications

which can incorporate codes and standards, are mandated by a government body and required, by law, to be complied with.

Regulations

This Code contains provisions that are considered minimum requirements necessary for safety.

Adequacy

This Code is intended as a design specification or an instruction manual for qualified persons

Intention

The requirements in this Code address the fundamental principles of protection for safety contained in Section 131 of International Electrotechnical Commission Standard 60364-1, Electrical Installations of Buildings.

Relation to Other International Standards

this Code are those that identify actions that are specifically required or prohibited and are characterized by the use of the terms "shall" or "shall not".

Mandatory Rules

this Code are those that identify actions that are allowed but not required, are normally used to describe options or alternative methods, and are characterized by the use of the terms "shall be permitted" or "shall not be required".

Permissive Rules

references to other standards, references to related sections of this Code, or information related to a Code rule, is included in this Code in the form of fine print notes (FPN).

are the conductors extending from the utility service terminals at the building wall to the service switch or to the main distribution center.

Mains

is set of conductors originating at a main distribution center and feeding one or more subdistribution centers, one or more branch circuit distribution centers, one or more branch circuits or combination of these. It may be primary - or secondary - voltage circuit, but its function is always to deliver a block of power from one point to another point at which the power capacity is apportioned among a number of another circuits.

Feeder

a feeder to a load which is made up primarily of lighting circuits.

Lighting feeder

a feeder to load of branch circuit for motors, heating, or other power loads.

Power feeder

a set of conductors originating at a distribution center other than the main distribution center and supplying one or more other distribution panelboards, branch circuit panelboards or branch circuit.

Subfeeder

refer to service, it is the conductors and equipment for delivering electric energy from the serving utility to the wiring system of the premises served.

Service entrance

portion of a wiring system extending beyond the final overcurrent device protecting the circuit and the outlet or the load.

Branch circuit

is a single panel or a group of panel units assembled in the form of a single panel. It contains busses tapped by fuse holders, with or without switches, or by circuit breakers, providing protection for- and, fi switches or circuit breakers are used, also providing control of - circuit for light, heat or power.

Panelboards

is a large single panel, frame, or assembly of panel with switches, overcurrent and other protective devices, and usually instruments mounted on the front and/or at the back.

Switchboards

the current, in amperes, that a conductor can carry continuously under the conditions of use without exceeding its temperature rating.

Ampacity

the algebraic sum of all electrical loads connected to the system. It does not take into account how and when these loads are being used.

Connected Load

indicates the net load that would be probably used at the same time for each load group.

Demand Load

are electrical loads that must be maintained during a power failure or an emergency. These loads include emergency or exit lights, building control systems, fire alarm systems, and elevators.

Emergency Load

are electrical loads that, when interrupted, may cause products to become nonoperational. _____________ are specifically required in health carefacilities.

Critical Load

a load where the maximum current is expected to continue for 3 hours or more

Continuous Load

is the ratio of the maximum demand of a system (or part of a system) to the total connected load on a system (or part of a system). This factor is always less than unity.

Demand Factor (DF)

is the ratio of the sum of the individual maximum demands of the various subdivisions of a system (or part of a system) to the maximum demand of the whole system (or part of a system under consideration).

Diversity Factor (dF)

refers to the system of wires and associated facilities belonging to a franchised distribution utility extending between the delivery points on the transmission or subtransmission system or generator connection and the point of connection to the premises of the end-user

Distribution System

electrical devices and equipment are superimposed on an architectural background.

Floor Plans

aka elementary diagram, illustrates the circuitry of a system and a basis for understanding the functions of an electrical system

Schematic Diagram

aka wiring diagram, It's not intended to illustrate the operating principle of the circuitry: rather, it used for installations by electricians.

Connection Diagram

This is simplified system diagram that shows the principal relationships among major equipment.

One-line Diagram

These diagrams express the physical relationship between different pieces of equipment or devices and are frequently used to show the vertical relationship between floors.
