4.1 Radial Wiring System
The radial wiring system is a common method where a single main cable runs from the distribution board to various points in the house. This system is straightforward and cost-effective, making it ideal for small to medium-sized homes. It involves point-to-point connections, ensuring each outlet or fixture is directly linked to the main supply. This setup simplifies installation and troubleshooting, as faults are easier to identify. However, it may require more materials if multiple outlets are needed. The radial system is widely used in residential settings due to its simplicity, reliability, and ease of maintenance, ensuring safe and efficient power distribution throughout the house.
4.2 Ring Wiring System
The ring wiring system involves a continuous loop of cable that starts and ends at the same point, typically the distribution board. This system is highly efficient, as it evenly distributes power and minimizes cable usage. Each outlet is connected in a circular configuration, ensuring that power is supplied from two directions. This setup offers higher reliability, as a fault in one section doesn’t disrupt the entire circuit. It is commonly used for lighting and power circuits, especially in larger homes. However, the complexity of installation and fault detection can be higher compared to radial systems. Despite this, the ring wiring system remains a popular choice for its balanced power delivery and robust design.
4.3 Lighting and Power Wiring Systems
Lighting and power wiring systems are essential components of a house’s electrical infrastructure. Lighting circuits are designed to power lamps, ceiling fixtures, and outdoor lights, typically operating at lower voltages.
