Question

Explain why there are two separate circuits one for high power rating appliances and the other for low power rating appliances

Answer 1

From consumer's  Fuse it si very important to note that there are two separate circuits, in house the lighting circuit with 5A fuse and power circuit with 15 A fuse.
The lightning circuit is for running low power rating devices like fan, bulb, radio, Tv etc. which draw small current.
On the other hand, power circuit is for running high power rating devices like electric iron,  room heater,geyser, Refrigerator etc which draw heavy current.
Each distribution is provided with a separate fuse so that if a fault like short circuits, overloading  occur  in one circuit, its corresponding fuse blows off but the other circuit remains unaffected.
