Explain with the help of a figure the ring system of wiring in domestic wiring.

(N/A) The ring system is as shown in the figure.
It consists of a ring-circuit. Wires starting from the main fuse-box run around all the main rooms of the house and then return to the fuse-box again.
The fuse-box contains a fuse with a rating of about $30\, A$.
$A$ separate connection is taken from the live wire of the ring for each appliance.
The terminal of the appliance is connected to the live wire through a separate fuse and a switch.
If the fuse of one appliance blows,it does not affect the other appliances.
For each appliance,the wires used for connection should have the proper current-carrying capacity.
