How to pay attention to safety when using fuse

The application of fuses is very extensive and has been in our lives. So how should we pay attention to safety when using fuses?

1. When installing the fuse on the power switch (switch), it is not allowed to operate with a point. The power switch should be opened in advance and the power supply should be disconnected. The purpose of cutting off power in advance is to prevent operating errors during the installation process from causing a short circuit of the power supply and preventing electric shock.
2. Frequent check and replacement of the Semiconductore fuse, replacement must be strictly in accordance with the requirements, can not use metal wire instead (such as copper wire, iron wire).
3. Do not increase the current level of the fuse at will. It needs to be replaced strictly according to the original fuse specifications. The current of the fuse is divided into three levels: 10A, 15A, and 20A.

4. If the new fuse is replaced and immediately blown out, it means that the circuit has a short circuit and needs to be repaired immediately.
5. When installing the fuse, do not screw the fuse too close, otherwise it will be squashed and reduce the flow of current, and it should not be too loose, so as not to cause excessive resistance at the joint.
6. Choose the fuse carefully, do not use inferior fuse, inferior fuse not only is not insured, but also brings danger.
7. Do not use a fuse that is too thin, otherwise it will be easily blown when the normal current passes, causing unnecessary power outages.
Sofielec briefly described how to pay attention to safety when using the fuse. Someone should be guarded when installing the fuse to prevent mistakes and safety accidents. Operators must have received professional training, non-professionals are not allowed to operate privately.
