Article 1.0-INTRODUCTION Purpose

(A) Practical Safeguarding. The purpose of this Code is the practical safeguarding of persons and property from hazards arising from the use of electricity.

(B) Adequacy. This Code contains provisions that are considered minimum requirements necessary for safety. Compliance therewith and proper maintenance will result in an installation that is essentially free from hazard but not necessarily efficient, convenient, or adequate for good service or future expansion of electrical use.

FPN: Hazards often occur because of overloading of wiring systems by methods or usage not in conformity with this Code. This occurs because initial wiring did not provide for increases in the use of electricity. An initial adequate installation and reasonable provisions for system changes provide for future increases in the use of electricity.

(C) Intention. This Code is intended as a design specification or an instruction manual to qualified persons.

(D) Relation to Other International Standards. 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.

FPN: IEC 603364-1, Section 131 Contains fundamental principles of protection for safety that encompass protection against thermal effects, protection against overcurrent, protection against fault currents, and protection against overvoltage. All of these potential hazards are addressed by the requirements in this Code. Scope.

(A) This Code has been approved and adopted by the Board of Electrical Engineering, Professional Regulation Commission.

(B) By virtue of authority vested in the Board under the Republic Act 7920 or national electrical engineering law, it hereby direct struct adherence to the provision of this Code. Enforcement.

(A) This Code is intended for mandatory application by the Office of the Building Official/EE over electrical installations.

(B) The Office of the Building Official/EE shall have the responsibility of implementing the provisions of this Code.

(C) This Code may require new products, constructions, or materials that may not yet be available at the time this Code is adopted. In such event, the Office of the Building Official/EE may permit the use of the products, constructions, or materials that comply with the most recent previous edition of this Code adopted by the National Building Code.

FPN: Application of electrical products and equipment for additional installation or replacement is suggested to be consulted with a licensed electrical practitioner prior to the installation for safety. Failure to do so may result in fire, serious injury or death. Mandatory Rules, Permissive Rules, Explanatory Material, and Appendices.

(A) Mandatory Rules. Mandatory rules of 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.

(B) Permissive Rules. Permissive rules of 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 terms shall be permitted or shall not be required.

(C) Explanatory Material. Explanatory materials, such as 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). Fine print notes are informational only are not enforceable as requirements of this Code.

Brackets containing section references to another NFPA document are for informational purposes only and are provided as a guide to indicate the source of the extracted text. These bracketed references immediately follow the extracted text.

(D) Appendices. Nonmandatory information relative to the use of PEC1 is provided in appendices. Appendices are not part of the enforceable requirements of PEC1, but are included for information purposes only. Interpretation.

Interpretation of this Code shall be by licensed electrical practitioners. In case of conflicting interpretations, these may be referred to the Philippine Electrical Coded Part 1 Committee for interpretation. Should disagreement remain, thereafter, the Committee’s interpretation shall be referred to the Board of Electrical Engineering who shall render the final decision. Examination of Equipment for Safety.

For specific items of equipment and materials referred to in this Code, examinations for safety made under standard conditions will provide a basis for approval where the record is made generally available through promulgation by organizations properly equipped and qualified for experimental testing, inspections of the run of goods at factories, and service-value determination through field inspections. This avoids the necessity for repetition of examinations by different examiners, frequently with inadequate facilities for such work, and the confusion that would results from conflicting reports as to the suitability of devices and materials examined for a given purpose.

It is the intent of this Code that factory-installed internal wiring or the construction of equipment need not be inspected at the time of installation of the equipment, except to detect alterations or damage., if the equipment has been listed by a qualified electrical testing laboratory that is recognized as having the facilities described in the preceding paragraph and that required suitability for installation in accordance with this Code.

FPN No.1: See requirements in Section

FPN No.2: Listed is defined in Article 1.1

FPN No.3: Appendix F contains an informative list of product safety standards for electrical equipment.

FPN No.4: Application of electrical equipment and devices shall always be consulted with a licensed electrical practitioner. Failure to do so may result in fire, serious injury, or death. Wiring Planning.

(A) Future Expansion and Convenience.

Plans and specifications that provide ample space in raceways, spare raceways, and additional spaces allow for future increases in electric power and communication circuits. Distribution centers located in readily accessible locations provide convenience and safety of operation

(B) Number of Circuits in Enclosures.

It is elsewhere provided in this Code that the number of wires and circuits confined in a single enclosure be varyingly restricted. Limiting the number of circuits in a single enclosure will minimizes the effects from a short circuit or ground fault in one circuit. Units of Measurement.

(A) Measurement Systems of Preference. For the purpose of this Code, metric units of measurement are in accordance with the modernized metric system known as the International System of Units (SI).

(B) Trade Sizes. Where the actual measured size of a product is not the same as the nominal size, trade size designators, shall be used rather than dimensions. Trade practices shall be followed in all cases.

(C) Extracted Material. Where material is extracted from another standard, the context of the original material shall not be compromised or violated. Any editing of the extracted text shall be confined to making the style consistent with that of the PEC1.

FPN: SI conversions are based on IEEE/ANSI SI 10-1997, Standard for the Use of International System of Units (SI). The Modern Metric System. Apprenticeship.

(A) Republic Act 7920 or the national electrical engineering law requires apprenticeship as one of the qualifications to the registration and licensure examinations for the Registered Master Electrician (RME), in order to practice electrical engineering in the Philippines. Knowledge and understanding of the Philippine Electrical Code, Parts 1 and 2 (PEC1 and PEC2) form part of the examination given.
