Explain about domestic electric circuits. (circuit diagram not required)

Explanation

(i) The first stage of domestic circuit is to bring the power supply to the main-box from a distribution panel, such as a transformer. The important components of the main-box are (i) a fuse box and (ii) a meter.
(ii) The meter is used to record the consumption of electrical energy . The fuse-box contains either a fuse wire or a miniature ciruit breaker (MCB).
(iii) The function of the fuse wire or a MCB is to protect the house hold electrical appliances from overloading due to excess current.
`*` red insulation - "live wire".
`*` black insulation - "neutral wire'.
(v) The electricity supplied to house is having an electric potential of 220V.
(vi) Both, the live wire and the neutral wire enter into a box where the main fuse is connected with live wire.
(vii) After the electricity meter, these wires enter into the main switch, which is used to discontinue the electricity supply whenever required.
`*` 5A rating - used to run the electric appliances with a lower power rating. Eg: Tube lights, bulbs and fans.
`*` 15A rating - used to run electric appliances with a high power rating. Eg: A/C, refrigerators, electric iron and heaters.
(ix) All the circuits in a house are connected in parallel, so that the disconnection of one circuit does not affect the other circuit.
(x) Parallel connection supplies an equal voltage.
Hint: Domestic electric current are those circuits use in household.
