The Thicker The Fuse In The Distribution Box, The Better
The fuse in Distribution box is not the thicker the better, but the appropriate thickness needs to be selected according to the current demand of the circuit.
The function of the fuse
The main function of the fuse is to play the role of overcurrent protection in the circuit. When the current in the circuit exceeds the maximum load that the appliance can bear, the fuse will automatically blow, thereby protecting the appliance from damage.
Choosing the right fuse
When choosing a fuse, it should be determined according to the specific needs of the circuit. If the current demand is large, a thicker fuse should be selected to allow a larger current to pass; however, if the current demand is small, using a thicker fuse may cause the fuse to be difficult to blow, so that the circuit cannot be cut off in time, causing safety hazards.
Correction of wrong ideas
Some people may think that the thicker the fuse, the better, but in fact this is incorrect. A too thick fuse may weaken or cancel the function of overcurrent protection, but make the appliance more vulnerable to damage. Therefore, when choosing a fuse, scientific principles should be followed and the selection should be made according to the actual situation.
