CE 313: Building System Design Overview

The Philippine Electrical Code (PEC) details regulations for all electrical systems, equipment, and installations within buildings.

Service drop conductors must maintain a minimum clearance of 2.50 meters from the highest roof point they pass over, with certain exceptions.

Service drop conductors should have a minimum clearance of 3 meters from the ground to ensure safety.

Rule XIII of the IRR of the NBCP mandates that all electrical systems in buildings comply with the Philippine Electrical Code (PEC).

Service drop conductors must maintain a minimum horizontal distance of 1 meter from windows, doors, porches, and other similar areas.

A professional electrical engineer must approve plans detailing power lines, cables, transformers, and other electrical equipment in buildings.

Electrical conductors carrying over 300 volts must be protected or made inaccessible when running along or near building surfaces.

No part of swimming pools, including a 3-meter area extending from the pool's walls, should be located beneath service drop conductors or overhead wiring.

Service conductors must be installed in rigid steel conduit or concrete-encased plastic conduit from the service drop to the meter base and then to the disconnecting equipment.

Supply conductors with over 300 volts must be guarded or kept inaccessible whenever they pass near or over buildings.

For safety, supply conductors near windows, verandas, fire escapes, or other accessible points require grounded conduit and barriers.

If service conductors are protected by approved fuses or circuit breakers, they can be installed using any recognized wiring method.

Capacitors exceeding 11 liters of flammable liquid capacity must be installed in a safety vault or outdoor enclosed area following PEC-1 guidelines.

Supply conductors carrying over 300 volts must maintain specific clearance distances based on their proximity to buildings.

Capacitors should be positioned to prevent physical damage and equipped with non-combustible cases and supports.

Ungrounded service conduits, metal fixtures, and similar non-current-carrying parts must be isolated, guarded, or grounded in urban areas to prevent accidental contact.

A set of standards and guidelines for the safe and proper installation and use of electrical systems in various settings.

The PEC ensures that electrical installations are safe, but not necessarily efficient or convenient.

PEC I covers electrical installations within buildings. PEC II covers electrical installations outside buildings.

The PEC applies to various locations, including buildings, electrical generating plants, substations, industrial plants, and transportation infrastructure.

The PEC covers the electric conductors, including optical fiber cables, installed within or on, to or from any location.

The PEC applies to both public and private buildings, ensuring safety in all electrical installations.

The PEC applies to places like railway switchyards and parking lots, ensuring safe electrical installations in these complex environments.

The PEC extends its reach to include mobile homes, recreational vehicles, and offshore facilities, highlighting its comprehensive scope.

A form used for electrical installations in the Philippines, requiring a registered Professional Electrical Engineer's signature unless the installation is small (20 lighting/receptacle outlets or less and 4000 VA, 230V).

A system designed to keep a building safe and secure, often communicating with the outside world using cellular or landline connections.

Systems installed in buildings to make them comfortable, functional, efficient, and safe.

Components of an electrical installation that must comply with specific rules except for those in aircraft, motor vehicles, and railway rolling stock.

Transport systems within a building, like elevators and escalators

The plan for a building's electrical system.

Systems for telephones, internet, and other forms of communication within a building.

A document containing detailed information about the electrical installation, including notes, specifications, diagrams, and load calculations.
