What Wire Is The Fuse Connected To?

Fuse Link is usually connected to the live wire of the circuit.

Installation location and reason:

Fuses are usually installed on the main circuit of the circuit and connected to the live wire. This is because when the current in the circuit is too large, the fuse will generate more heat, which will automatically melt and cut off the circuit to protect the safety of the equipment and circuit.
If a fuse is installed on each of the live and neutral wires, when the circuit is overloaded, it is possible that the fuse on the neutral wire will melt while the fuse on the live wire will not melt, which will cause the electrical appliance to be energized even though it cannot work, posing a safety hazard.

Brief description of working principle:

When the current in the circuit exceeds the design requirements, the heat generation rate of the fuse will be greater than the heat dissipation rate, causing the temperature of the fuse to rise above its melting point, resulting in melting.

Other related information:

The role of the fuse: In addition to playing a protective role in the circuit, fuses are also commonly used to connect sockets in household circuits to prevent short circuits or overloads caused by electrical failures.
Construction of the fuse: The fuse is usually made of a lead-antimony alloy with a high resistivity and a low melting point. This material can melt quickly when the current is too large, thereby cutting off the circuit.
