Answer:

Philippine Electrical Code (PEC) Article 1.4.10 states that all electrical installations in educational and research facilities must be designed and installed to provide adequate lighting. This is important to ensure that students, teachers, researchers, and other individuals working in these facilities can see clearly and work safely. In addition to general lighting, specialized lighting may be required for specific tasks or activities, such as laboratory work or research. The PEC provides specific requirements and guidelines for the design and installation of electrical systems in educational and research facilities to ensure compliance with safety standards and codes.
