What you'll learn

  • Understand house wiring and what your electrician is doing, troubleshoot minor electrical issues

Course content

3 sections • 18 lectures • 1h 11m total length

  • Welcome1:33

    Explore the basics of electrical wiring with simple diagrams covering incoming supply, panels, components, circuits, conductor sizing, load distribution, breakers, and residual current devices, plus an apartment illustration.

  • Looking inside a Distribution Board6:15

    Explore a typical three-phase distribution board to see how brown, black, and gray phases connect to busbars and blue neutral, with fuses and breakers distributing power to loads.

  • Tracing a circuit inside a Distribution Board1:12

    Trace a circuit from the supply through the distribution board and busbar, fuse, switch, and circuit breaker to the load, then back via the neutral to complete the path.

  • Radial Wiring Circuit0:55

    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.

  • Ring Wiring Circuit1:26

    Discover how ring wiring circuits connect multiple sockets in parallel, tracing live and neutral paths from the circuit breaker to each socket and back, with earth continuity.

  • Wiring Three Phase Load1:16

    Explore wiring a three-phase load, connecting each phase to its own breaker on a distribution board, and delivering power to a motor or outlet.

  • Wiring of Earth conductor2:43

    Connect the line to the switch and lamp through neutral, wiring an earth strip for safety. Ensure fault current travels via the earth path to protect metal equipment.

  • Choosing Wire and Breaker Sizes3:53

    Select 4 mm2 to 6 mm2 wire for typical loads like 2.5 kW heaters and a 20 to 30 A breaker, balancing safety.

Requirements

  • It is helpful to have high school level knowledge about Electricity

Description

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!
