The purpose of this Code is the practical safeguarding of persons and property from hazards arising from the use of electricity. 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. Philippine Electrical Code, Part 1 (2017 Edition) PURPOSE: Intention. This Code is intended as a design specification or an instruction manual to qualified persons. 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 60363-1, 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 of PEC It covers the installation of electrical conductors, equipment, and raceways; monitoring, , signaling, and communications conductors, equipment, and raceways; and optical fiber cables and raceways installed within or on, to or from: Public and private buildings, including but not limited to residential, commercial, industrial, institutional, cultural, agricultural, agro-industrial, planned unit development and all other buildings/premises that may require practical safeguarding of persons and property from the hazards arising from the use of electricity. Electric generating plants Industrial plants Transformer stations Scope of PEC Permanent and temporary substations, etc. Airfields Railway switchyards Yards, carnival, parks, parking and other lots Quarries and mines Watercraft Dockyards Trailers Mobile homes and recreational vehicles Offshore facilities Not covered by PEC: (1) Installations in railway rolling stock, aircraft, or automotive vehicles (2) Installations of railways for generation, transformation, transmission, or distribution of power used exclusively for operation of rolling stock Authority This Code has been approved and adopted by the Board of Electrical Engineering, Professional Regulation Commission. By virtue of authority vested in the Board under the RA 7920, it hereby direct strict adherence to the provisions 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. Mandatory Rules, Permissive Rules, Explanatory Material and Appendices 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. 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 the terms shall be permitted or shall not be required. Mandatory Rules, Permissive Rules, Explanatory Material and Appendices Explanatory Material. Explanatory material, 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 and are not enforceable as requirements of this Code. Appendices. Nonmandatory information relative to the use of the PEC1 is provided in appendices. Appendices are not part of the enforceable requirements of the 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 PEC 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. Wiring Planning 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. Number of Circuits in Enclosures.
