Explore how a radial wiring circuit feeds a lighting circuit from a black busbar to a single breaker, then through the switch to the load and back to neutral.
Explain the function of the earth wire in protecting against electrocution by directing fault current to earth, with fuses and an rcd providing safety.
Master wiring socket outlets in a ring main using MZB protection, with line, neutral, and earth connections, to dining, kitchen, and doorbell, while keeping total load within the circuit rating.
Learn to select circuit breaker and wire size for lighting loads with a chart, covering up to 600 W, 600–1200 W, and 1200–1800 W ranges.
Welcome to the course Basics of Electrical Wiring. This is a basic course for anyone who wants to know more about the all-important electricity that brings the power to run modern life. Even though electrical wiring appears complicated we have simplified things for you by using simple wiring diagrams which clearly illustrates all the basic components of electrical wiring - starting with incoming supply, consumer panel, wiring components, wiring different circuits like radial, ring, parallel, single phase, three phase and so on. We have also gone into the selection of conductor sizes and circuit breakers, distribution of load between phases and the application and wiring of Residual Current Devices (GFCIs). As a bonus section a detailed wiring illustration of a sample apartment is provided where all the principles taught in the first part is applied in practice. Whether you're a beginner or looking to enhance your expertise, this course will empower you to understand the principles and practice of house wiring. At the end of this course you will be in a position to know exactly what your electrician is supposed to do in your house and even be able to troubleshoot minor electrical problems yourself. Let's embark on this electrifying journey together!
