Design the wiring of a small house using an interior layout to create wiring plans, determine sub circuits, calculate load, and select wires, circuit breakers, and the distribution board.
Design the wiring layout for a small house, placing fan, light, and power points on switchboards, calculating loads, and selecting circuit breakers, main distribution, and earthing—focusing on basic configuration.
Understand basic electricity rules for domestic installations: separate sub circuits for lighting and power, single circuit breaker protection, two lighting circuits, and 800-watt lighting plus 3000-watt power loads.
Design of subcircuits explains multi-load circuits with single distribution board breakers, load calculation using appliance power values, and selecting cable sizes for lights and sockets.
Design the layout of subcircuits for house wiring, detailing light points L1–L7, switchboards SB1/SB2, neutral wiring, and 1.5–2.5 mm square cables to stay within power limits.
Calculate the total connected load for a house by summing lights and outlets, then decide single-phase versus three-phase supply per regulation.
Select the main switch and main distribution board by calculating the total current demand and choosing standard protective devices. Include RCBO, RCCB, and six-way DB for future needs.
Learn how to choose home cables by evaluating conductor material (copper preferred), insulation, voltage rating, current capacity, and safety standards, including certifications, fire-retardant grades, LOI, and rodent resistance.
Trace the path from the utility meter to the house distribution board, through the main circuit breaker to the earth unit, and onward to loads with copper eight mm² conductors.
In this course you will learn how to design the wiring of a small house by taking a typical example. The course starts with an overview and explanation of typical wiring regulations. Given the interior design layout, you will learn how to create wiring layout, determine the subcircuits, calculate loads, select wire sizes, circuit breakers, main switch, Distribution board and earthing system. I have also gone through the exact wiring of each subcircuit. As a bonus section I have also gone into detail how to choose cables for your house. I have chosen only the basic configuration without going into details of wiring regulations or specifications and collated just the necessary information to get started with wiring design of a whole house in the shortest time possible. This course simplifies basic aspects of house wiring design even understandable to a layman, which is otherwise cumbersome to comprehend as it demands reference to many regulations and collating data from various sources. At the same time this course will act as a springboard for even technicians and engineers starting their career for more advanced wiring design. This course will help anyone who want to know how his or her house is wired, make new wiring designs or upgrade existing wiring design, without being totally reliant on the electrician.
