Electrical Wiring Components and Accessories
IntroductIonElectricity requires an electric path to flow and there are many conducting materials used for this purpose. There are many semi conducting materials which are used to reduce the voltage and also drop the current flow. There are non-conducting materials which are used as insulation during working on live-lines. In this unit we will study how the household or industrial Wiring is done and what materials are essential for household or industrial Wiring . We will also study the different types of Wiring and how they is 1: IdentIfyIng and SelectIng the Wiring MaterIalS and coMponentSWiring materialsElectrical wire is made of materials like copper, aluminium and silver.
the older types of fuses. Circuit breakers are small . devices used to control and protect the electrical panel and the other devices from overflowing of electrical power (Fig. 3.17). Uses of MCB. Home electrical panels. As with all breakers, the MCB is designed to protect the house from circuit overload. An MCB is much s. afer . Fig. 3.15 PVC
