Things to know about the safety ground wire for your home appliances

Some household electrical products when operating will have static electricity on the surface, which is not dangerous but will cause discomfort when we touch it. In this article, Dien May XANH will show you how to solve this problem by connecting the ground wire.


1 What is a ground wire?

The ground wire, also known as the ground wire, is a short electrical wire connecting appliances using high voltage 220V such as water heaters, washing machines, refrigerators, etc. to the ground to solve problems. electrical leakage outside these electrical appliances.

2 Why should we connect the ground wire to the devices?

With equipment such as , often placed in places with high humidity such as kitchens, bathrooms … make the electric motors and internal circuits wet, causing electric leakage. The shell of the devices is designed with metal, so it is easy to transmit electricity, causing unexpected electrical accidents for users to accidentally touch.

In addition, in winter, static electricity is more likely to occur on the surface of the devices, causing "splitting electric shock" when touched. In Vietnam, 3-prong sockets with hot wire jacks, cold wire jacks and grounding holes are also not common, and equipment manufactured for Vietnam sometimes only has 2 pins to reduce costs. electric leakage is more likely to occur.

Because of the above reasons, grounding is considered a simple and safe measure to prevent electrical accidents.

3 What equipment will need to be grounded?
