SOLUTION

Different electrical loads are required to be switched in and switched off quite frequently. We use a switch to make and break the electrical connection to a load. This could be achieved by inserting a switch anywhere in the circuit. Switches must be connected in the circuit of a live wire so that the supply is dead when the switch is in the off position. If the Switch is provided in the neutral, there is a potential between the live wire and earth, even with the switch in the off position. This would cause a shock to the person repairing the lighting points with the switch in the off position. Switches for domestic lighting are standardized at 5 and 15-ampere capacity.

The switches for domestic installation have been standardized at 5A capacity for lighting circuits (such as electric lamps, fans, mobile chargers, etc.) and at 15A capacity for power circuits (such as microwave oven, washing machine, room heater, geyser, air-conditioner, etc.
