Preparation of Plans, Supervision of Installation, and Application of the Philippine Electrical Code

Preparation of Plans, Supervision of Installation, and Application of the Philippine Electrical Code in the Philippines

In the Philippines, the practice of electrical engineering is regulated under Republic Act No. 7920, also known as “An Act Providing for a More Responsive and Comprehensive Regulation for the Practice, Licensing, and Registration of Electrical Engineers and Electricians.” This legislation sets forth the guidelines and standards for the preparation of plans, supervision of installation, and application of the Philippine Electrical Code (PEC) to ensure safety, efficiency, and compliance in electrical installations. This article delves into the specific provisions of Section 34 of RA 7920, highlighting the roles and responsibilities of professionals in the field of electrical engineering.

Republic Act No. 7920: An Overview

  • Republic Act No. 7920, enacted on February 24, 1995, provides a legal framework for the regulation of electrical engineers and electricians in the Philippines. It aims to protect the public by ensuring that electrical installations are designed, installed, and maintained by qualified and licensed professionals. The Act mandates the creation of the Board of Electrical Engineering under the Professional Regulation Commission (PRC), which is responsible for administering the licensure examinations and regulating the practice of the profession.

Section 34: Key Provisions

Preparation of Plans

According to Section 34 of RA 7920, it is unlawful for any unauthorized person to prepare plans, electrical valuations, or specifications for any electrical wiring, equipment, or system. Only professionals licensed under this Act, specifically professional electrical engineers (PEEs), registered electrical engineers (REEs), and registered master electricians (RMEs), are authorized to undertake these tasks.

  • Professional Electrical Engineers (PEEs):
    • PEEs are responsible for the overall design and preparation of plans, ensuring that these plans meet the technical and safety standards set forth in the PEC.
  • Registered Electrical Engineers (REEs):
    • REEs may assist PEEs in the preparation of plans and may take charge of simpler electrical installations, ensuring compliance with the PEC.
  • Registered Master Electricians (RMEs):
    • RMEs are tasked with the execution and supervision of electrical installations based on the plans and specifications prepared by PEEs and REEs.

Supervision of Installation

The Act mandates that no electrical installation shall be undertaken unless it is supervised by a licensed professional. This supervision ensures that all work is performed in accordance with the PEC and that the installation meets all safety and technical standards. The responsible charge or supervision can be carried out by a PEE, REE, or RME, depending on the complexity and scope of the project.

  • Supervision by PEEs: For large-scale or complex electrical installations, PEEs provide direct supervision to ensure compliance with the PEC and other relevant standards.
  • Supervision by REEs and RMEs: For smaller or less complex installations, REEs and RMEs may take on supervisory roles, ensuring that the work aligns with the prepared plans and the PEC.

Application of the Philippine Electrical Code (PEC)

The PEC is a set of standards and guidelines designed to ensure the safe installation and operation of electrical systems in the Philippines. It covers various aspects of electrical work, including wiring methods, equipment installation, and maintenance practices.

  • Compliance with the PEC:
    • All electrical plans, designs, and installations must adhere to the standards outlined in the PEC. This compliance is crucial to prevent electrical hazards, ensure system reliability, and protect public safety.
  • Construction Permits:
    • Before commencing any electrical installation, a construction permit must be secured. This permit indicates that the plans have been reviewed and approved by the relevant authorities and that the installation will be carried out under the supervision of a licensed professional.
  • Government Agency Requirements:
    • In addition to the PEC, electrical installations must also meet the routinary fiscal and ministerial requirements of the government agency exercising jurisdiction over the particular installation. This may include inspections, permits, and certifications to ensure that all regulatory standards are met.

Practical Implications

Ensuring Safety and Compliance

  • The strict regulations and requirements set forth in RA 7920 and the PEC are designed to ensure the safety and reliability of electrical installations. By requiring that only licensed professionals prepare plans and supervise installations, the law aims to mitigate the risks associated with electrical work, such as fire hazards, electrical shocks, and equipment failures.

Professional Accountability

  • The Act holds licensed professionals accountable for the quality and safety of their work. PEEs, REEs, and RMEs must adhere to ethical standards and maintain their professional competence through continuous education and adherence to the PEC.

Economic and Legal Considerations

  • Compliance with RA 7920 and the PEC can have significant economic and legal implications for businesses and individuals involved in electrical installations. Non-compliance can result in legal penalties, project delays, and increased costs due to rework and corrective measures.


Republic Act No. 7920 and the Philippine Electrical Code form the cornerstone of electrical engineering practice in the Philippines. These regulations ensure that only qualified and licensed professionals are involved in the preparation of plans, supervision of installation, and application of the PEC. By adhering to these standards, the industry can safeguard public safety, ensure the reliability of electrical systems, and uphold the professional integrity of electrical engineers and electricians.
