Question

State the function of each of the following in a house circuiting:
(a) main fuse, and
(b) main switch.​

Answer 1

Answer:

a) Main fuse is connected in the live wire and in case of high current it gets burnt and cut the connections to save appliances. (c) Main switch is connected in the live and neutral wires. It is used to cut the connections of the live as well as the neutral wires simultaneously from the main supply.

b) The main circuit breaker controls the electricity flow from your two main wires to your hot buss bars. Tripping the main circuit breaker disrupts the 240 volts of electricity before it reaches your branch breakers. When the main breaker is tripped, everything in your home is off.
