Question

Draw a circuit diagram to explain the ring system of house wiring. State two advantages of it.

Answer 1

Advantages of ring system over tree system

1. In a ring system the wiring is cheaper than tree system.

2. In the ring system, the sockets and plugs of the same size can be used while in a tree system sockets and plugs are of different size.
3- In the ring system, each appliance has a separate fuse due to which if there is a fault and the fuse of one appliance burns it does not affect other appliances; while in a tree system when the fuse in one distribution line blows, it disconnects all the appliances connected to that distribution circuit.
