Question

Where the main fuse in a house circuit is connected?

Answer 1

Fuse:

1. Before entering the domestic circuit, the fuse is usually linked in series with the live wire. This would be accomplished because only the live wire has a high potential of $200\mathrm{volts}$, whereas the neutral wire has had no potential.
2. This same fuse has a high rating of around $50\mathrm{amps}$. As a result, it avoids any harm to the complete electrical wire entering the house, such as fire, caused by a short-circuit as well as overloading.
3. A principal fuse box, also known as an electricity board as well as a fuse board, has been developed to function and protect your apartment's electrics. The primary fuse is located throughout the live wires that come out of the $\mathrm{kWh}$ meter's rectifier output.

Therefore, the main fuse in a house circuit is connected to the live wire.
