It is essential to have proper electrical wiring at homes. But it is more challenging and important to split the circuit into all the rooms, in particular for the bathrooms and the kitchen.
Why is the electrical wiring of a kitchen of greater importance than of any other room?
Kitchen has the most heavy duty electrical appliances out of the rooms in the house. Thus, its proper wiring is extremely necessary. Heavy duty electrical appliances include microwave, dishwasher, refrigerator and sometimes geyser. In this case, it is important to split the circuit so as to escape the danger of overloading and in many cases fire.
The homeowners should be cautious about using different circuits for all the rooms, especially kitchen.
Different circuits do not mean that the homeowners install different circuits for all the different appliances. They can distribute the lights and all the electrical appliances in 2-3 circuits.
For e.g. one circuit can be given to light/fans and the refrigerator, other for microwave/oven and mixer and the third one for the dishwasher and the geyser (if present).
By separating the circuits the chance of overloading decreases substantially.
Besides electrical circuit, the wire size use is also necessary. There are different factors on which wire size depends on. They are a gauge of the wire and for what purpose will the wire be used. For the domestic purpose, 2.5mm and 4mm wires are utilised. The 4 mm wire is used for heavy electrical like a 2-2.5 tonne AC. 6mm wires are used to join main circuit boxes at home to the panel boxes of the society. A 2.5 mm wire is used for internal wiring. It should not go below 2.5 mm.
Some electricians use 4mm wire for all heavy as well as light electrical appliances. This solves the problem of overloading or heating up of the wire.
In rarest of the cases, the electricians go for 6 mm wiring. The homeowners will never have to worry about changing the wiring unless there are some serious problems.
