Outline
- Electrical System
- Rule XIII of the IRR of the NBCP: Electrical Regulations
- Philippine Electrical Code
- Other Building Service Systems
Electrical System Details
- Diagrams show components like lamps, cords, plugs, wall switches, power lines, sub-panels, main panels, circuit breakers, fuses, transformers, service drop, conduits, service entry wires, meters, and service head.
- Electrical distribution to buildings is described.
- Rule XIII of the IRR of the NBCP governs electrical regulations.
- Conductors exceeding 300V should be guarded or inaccessible to promote safety
- Electrical supply conductors near windows, verandas, fire escapes, should be properly guarded.
- Abandoned electrical lines should be removed.
- Service conductors must be installed in rigid steel or concrete encased plastic conduit from service drop to meter base to disconnect equipment.
- Capacitors on electric circuits with over 11L of flammable liquid must be in enclosures complying with PEC-1.
Philippine Electrical Code (PEC)
- Objectives include establishing quality and electrical work standards for safe use.
- This includes light, heat, power, communications, signaling
- PEC ensures safety and efficiency in electrical installations.
- It ensures future adaptability and does not need to be overdesigned.
- PEC part 1 covers indoor electrical installations
- PEC part 2 covers outdoor installations.
Scope of PEC
