On June 30th, an employee of a power supply company in Gansu received a call from customer Yang, saying, "My house has a power outage, and the TV still has a burning smell. Can you please come over and take a look
After the employees of the power supply company had a preliminary understanding of the power outage at Yang's house, the director of the office immediately arranged for the duty officer Wang to rush to the customer's house. Pushing open the door of Yangmoujia's room, a burning smell filled the room. Therefore, Wang immediately began to carefully inspect the wiring direction of Yang's house. With years of work experience, Wang went straight to the customer's knife switch and found that the fuse was intact without any signs of burning out. Upon closer inspection, he found that the fuse was actually replaced with copper wire.

With years of work experience, Wang went straight to the customer's knife switch and found that the fuse was intact without any signs of burning out. Upon closer inspection, he found that the fuse was actually replaced with copper wire
So, Wang immediately cut off the power and replaced the fuse in the knife switch with a regular fuse. A few minutes later, Wang inspected Yang's house and found that there were aging wires under the eaves that caused the insulation to fall off and cause a short circuit. He quickly resolved the problem and the customer's light turned on again.
Immediately, Wang explained to Yang, "Fuses should never be replaced with copper wire. The melting point of copper wire is relatively high, and it cannot provide protection when there is a short circuit in the wire and a large current passes through. This is why your TV has a burning smell
I didn't know there was so much knowledge in the fuse. Thank you so much this time, I will pay attention to it in the future. "Yang, holding two staff members, expressed his gratitude.
