Question

Why is the main fuse connected in the live wire before the ring system? Explain.

Answer 1

The main fuse is connected in the live wire to safeguard the entire household circuit from excessive current. The live wire carries high voltage (220 V). Placing the fuse right before the ring system ensures that if there is a short circuit or overloading, the fuse wire melts and breaks the connection instantly. This cuts off the high-voltage supply before it can enter the ring loop, preventing electrical fires and protecting appliances.
