Question

The main fuse is connected in ______.

Options

• earth wire

• neutral wire

• live wire

• none of these

Answer 1

The main fuse is connected in live wire.

Explanation:

The live wire carries high voltage (220 V) into the house. Connecting the fuse in the live wire ensures that if an excessive current flows, the fuse melts and breaks the circuit immediately. This completely cuts off the high-voltage supply before it can reach and damage any household appliances.
