What is the role of the ground wire

Many people know that we are installing plumbing and electricity when the electrician will be connected to a ground line at each switch, but there are people who think that the ground line can have nothing, in fact, the role of the ground line is critical, so when doing plumbing and electricity should not be ignored the installation of the ground line, then the role of the ground line is what? Today we will look at it.

What is the role of the ground wire

1, protection of electrical appliances, electrostatic discharge process will produce a large number of charges, if the electrical appliances do not have the appropriate barrier will be on the electrical appliances and damage, the role of the ground wire is the role of the electrical appliances and the ground under the ground between the wires, can effectively avoid electrical appliances are strong charge damage.

2, lightning, before if the occurrence of lightning poles and electrical equipment are easily damaged by lightning strikes, so now will be grounded, so you can prevent lightning, to avoid damage to electrical appliances.

3, to protect the normal work of the machine, a lot of electrical appliances is necessary to electricity to work, especially in the medical field, the role of the ground wire is to be able to avoid a sudden power outage will not be affected, you can run some of the small load potential.

4, the protection of human safety, if the human body electrocution occurs, the ground can lead the current to the ground so that the current through the human body will be much smaller, thus protecting the safety of human life.

What to pay attention to home electricity

1, avoid contact with metal objects and sockets, most of the metal will have a conductive function, so be sure to pay attention to not touching the power supply with metal appliances to prevent electric shock.

2, home appliances are best not long in the working state, time is easy to aging, or high temperature leading to the circuit burned out danger.

3, electrical appliances out of order can not be disassembled, if the internal parts are not connected to the appliance is easily damaged, it is best to find a professional to deal with.

4, in the unplugging time many people are directly hit the wire that end, this is not safe, the wire is easy to pull out, and time is also easy to aging, the correct approach should be to hold the plug slowly pull out.
