Single Phase and Three Phase Wiring

We will learn about different electrician tools, available sizes and their proper handling. We should use proper tools for a particular type of job. Use of improper tools may leads to serious injuries to the electrician and the tool may also be damaged. So, here we will also learn about different precautions to be taken while using and handling of these tools. The sharp edged tools, such as pocketknife,chisels etc., should never be put in pocket without proper shield. While working with such tools, care should be taken not to place hand or finger in the path of motion of the cutting tools. Also, care should be taken not to hand over the sharp edge tool with its sharp edge side. Different electrical wiring accessories are used for wiring single phase and three-phase wiring. So, we will have an exposure about shape, size and use of different electrical accessories commonly used for wiring.

Fuses and miniature circuit breakers are used as safety device for any electrical circuit. When the current drawn from the circuit, increases beyond the pre-set limit,the supply is switched off. Different wiring systems are used in domestic and factories, depending upon the environmental condition. We will also study about the supply of electricity from service pole as well as internal wiring, starting from energy meter to I.C.T.P. main switch and other small capacity main switches, to have an independent control of various circuits/sections.
