Explain the domestic electric circuit with the diagram​

Answer 1

Below is the diagram of domestic electric circuit.
From the power station, electricity is supplied to our houses at 220V. The electric line is connected to the meter-box in a house through a fuse of high rating (company fuse). In the main switchboard, fuses are kept for different circuits as per requirement. Through the main switch they are connected to the line wires in the house.
These wires carry two different values of current in the house:
15A current line is connected to the appliances of higher power ratings like geyser, air conditioner, etc.
5A current line is connected to appliances of low power rating like tube light, television, etc.
Besides, another important aspect of domestic electric circuit is earthing. The earthing wire is connected with the metal plate and dumped deep near the house. In a domestic electric circuit, red coloured wire is used as live wire, black coloured wire as neutral wire and green coloured wire as earthing
