Study Notes
- Wiring methods ensure safe and efficient electrical installations in the Philippines
- Selecting the right wiring method depends on the environment, building type and compliance with the Philippine Electrical Code (PEC)
- The Philippine Electrical Code (PEC) governs the design, installation, and maintenance of electrical systems
- The PEC ensures safety, reliability, and compliance with standards
Conduit Wiring
- Wires are enclosed in protective tubes or conduits to shield them from damage
Electrical Metallic Tubing (EMT)
- Lightweight and easy to install
- Ideal for indoor use in spaces such as offices and commercial areas
- Limited corrosion resistance, unsuitable for outdoor or wet areas
Rigid Steel Conduit (RSC)
- Provides heavy-duty and maximum protection
- Suitable for industrial and outdoor installations
- High cost but offers excellent durability
PVC Conduit
- Corrosion-resistant and cost-effective
- Commonly used in residential installations
- Must be protected from UV exposure when used outdoors
- Offers high mechanical protection and is easy to maintain
- Requires skilled labor for installation with higher costs
Surface-Mounted Wiring
- Wires are enclosed in raceways mounted on walls or ceilings
- Ideal for renovations or temporary setups where embedding wires is impractical
- Uses PVC or metal raceways for materials
- Offers quick installation and is easy to modify
- Less aesthetic and may accumulate dirt
Concealed Wiring
- Wires are embedded within walls, floors, or ceilings, hidden from view
- Common in modern residential and commercial buildings
- Provides a clean and neat appearance with protection from physical damage
- Difficult to modify or repair after installation
Cable Wiring
- Includes Non-Metallic Sheathed Cable (NM Cable) and Armored Cable (AC)
Non-Metallic Sheathed Cable (NM Cable)
- Common for residential indoor wiring
- Quick and cost-effective
- Not suitable for exposed or wet locations
Armored Cable (AC)
- Wires are enclosed in a metal sheath
- Offers extra mechanical protection
- Suitable for exposed wiring in areas prone to damage
Busbar Trunking System
- A pre-fabricated system for power distribution using metal busbars enclosed in a protective casing
- Used in large buildings, factories, and malls
- Provides high current capacity, and is easy to install
- Higher costs and requires planning
Underground Wiring
- Wires are installed underground using conduits or ducts
- Used for outdoor lighting and power distribution for outdoor buildings
- Hidden from view with no interference with landscapes
- Costly installation and difficult to repair
Aerial Wiring
- Wires are supported by poles above ground
- Used in rural areas and temporary setups
- Economical and quick to install
- Exposed to weather and physical damage
Safety Considerations
- Always refer to the PEC for specifications on material, installation methods, and environmental suitability
- Use appropriate PPE such as gloves, safety goggles, and insulated tools
- Consider heat, humidity, and potential hazards in the wiring location
- Properly size wires and breakers to handle the load
