The purpose of the Philippine Electrical Code is the practical safeguarding of persons and property from hazards arising from the use of electricity. This code contains provisions that are considered minimum requirements necessary for safety. This code is intended a a design specification or an instruction manual to qualified persons. – PEC 2017
The “Building Code Requirements for Structural Concrete” (“Code”) covers the materials, design, and construction of structural concrete used in buildings and where applicable in nonbuilding structures. The Code also covers the strength evaluation of existing concrete structures. Download Free PDF. Download Free PDF.
Chapter 1 General
Revisions:
New definitions have been included, notably Office of the Building Official/EE (OBO/EE), National Electrical Engineering Law and Service Protective Device.
- The OBO/EE refers to the licensed electrical practitioner employed with the Office of the Building Official. He/she replace the Authority Having Jurisdiction (AHJ) in the Code’s various provisions.
- The second new definition expounds references to Republic Act 7920 (RA 7920) which is the current national engineering law. This way, the nation engineering law remains relevant should Republic Act 7920 be superseded.
- Service Protective Device defines the new equipment addition to Code provisions related to service equipment.
Also, three important new sections have been added:
- (1) Section 1.0.1.10 Apprenticeship
- (2) Section 1.10.1.24 Available Fault Current (which require markings of such on the service equipment and would necessarily need short-circuit calculations complimenting Section 1.3.2.1(F)(4),
- (3) Section 1.10.1.25 Lockable Disconnecting Means. Arc-Flash Hazard Analysis has been added to the requirements under Section 1.3.2.1(F) Design Analysis a 1.3.2.1(F)(5).
Chapter 2 Wiring and Protection
Important revisions include:
- (1) Deletion of requirement for arc-fault circuit-interrupter due to non-availability for Philippine specifications,
- (2) In addition to Code requirements on multi-occupancy buildings, their application to site developments -where group(s) of single detached buildings are constructed – have been included,
- (3) Clarified and expanded provisions on Service Protective Device when installed ahead of Service Equipment, and
- (4) clarified provisions on grouping of Disconnecting Means
Chapter 3 Wiring Methods and Materials
Revisions:
Rationalized ampacity tables of conductors – copper and aluminum – for three conductors in raceway and in free air up to 2000 volts, Tables 3.10.2.6(B)(16) and 3.10.2.6(B)(17), respectively. Ampacities are based on current densities of the cross-sectional areas of the conductors.
- Article 3.10 has been expanded to two parts. Four new articles have also been added:
- (1) Reinforced Thermosetting Resin Conduit: Type RTRC,
- (2) Cablebus,
- (3) Low-voltage Suspended Ceiling Power Distribution System,
- (4) Outdoor Overhead Conductors over 1,000 V.
Chapter 4 Equipment for General use
Revisions:
Previous editions of PEC1, at one time or another, permitted a specific number of overcurrent protective devices in a panel board enclosure. This limitation has been removed from PEC1 2017 and is required only (maximum of 48) if the panel board is protected on its supply side by two sets of circuit breakers or two sets of fuses.
Fixed Electric Space-heating Equipment has been expanded while Fixed Resistance and Electrode Industrial Process heating equipment has also been added.
Chapter 5 Special Occupancies
Revisions:

Revisions:
Interconnected Electric Power Production Sources and Optical Fiber Cables have been expanded. Five new articles have been added:
- Energy Storage Systems,
- Critical Operations Power Systems,
- Stand-Alone Systems,
- Direct Current Microgrids, and
- Fire-Resistive Cable Systems.
Chapter 8 Communication Systems
Revisions:
Added new Article 8.40 – Premises-Powered Broadband Communications-Systems has been added.
Chapter 9 Watercrafts
Chapter 10 Tables
Revisions:
A new Table 10.1.1.10 has been added.
