To ensure comfortable and safe operation of electrical appliances, they must be grounded. It so happened that most of the household appliances are located in rooms with a high level of humidity - this is the bathroom and the kitchen. Illiterate installation in conjunction with such conditions can lead to unpleasant situations. Next, we will tell you what to do if you decide to do the washing, touch the machine and get an electric shock.

Why do you need grounding?
Some owners believe that the standard grounding of the outlet should be enough, and small bumps appear due to malfunctions of household appliances. In fact, even a serviceable machine can be shocked if it is not grounded. You can not hesitate with this, since the lack of grounding contributes to the accelerated wear of the machine.
Usually people don’t spend time on this work, while the machine simply “plucks” when it touches the body or mixer. The situation changes after the owner receives a tangible blow. This is the first reason - sooner or later you or your relatives will receive a strong blow that can harm your health.
As for the second factor, this is the protection of expensive equipment. It is known that devices stuffed with modern electronics quickly become unusable if there is no grounding. Elements of technology can break even with minimal static. As a result, you will have to contact the service center for repair, and in some cases to buy a new machine. It is recommended to ground the equipment immediately after purchase - this action will eliminate the main risks.
How is the grounding of the machine in the apartment?
The simplicity of the most popular method is that the grounding is carried out from a conventional battery, which is in all apartments. The method works - the machine stops electric shock. But there are serious risks that you need to know about in advance: after a few years of such "protection" pipes will start to flow. The cause of this defect is the extreme effect of electricity. But for the first time you can use this method:
- You just need to take a single-core wire;
- One end must be brought to the battery, and the second to the metal element of household appliances;
- The wire should be securely fixed. For these purposes, a metal clamp is used;
- For the circuit to work, it is necessary to prepare the pipe section: remove the old enamel and lead the wire.
Grounding the bathroom
The first step is to ground the outlet, which is located in the bathroom. For these purposes, it is required to lay a separate line from the shield to the typewriter. For this, a three-wire wire with a copper section is used - usually take 2.5 or 4 mm2. It is recommended to put a new outlet - the current should be 16 A.
Standard grounding circuit
Laying is performed by open or closed method:
- The first method involves the installation of special boxes from the outlet to the shield.
- In the second option, you need to make channels in the wall, lay the wiring and then cover with a layer of plaster.
As you understand, the method with boxes is not only more aesthetic, but also safe. If you do not have the opportunity to draw a wire from the machine, then the outlet can be installed next to the shield and in the future use an extension cord. When the outlet is grounded, you can go to the machine itself.
IMPORTANT! All operations should be carried out only with a complete power outage.
It remains to make the main connection. If you have a modern electrical panel installed, then there will be a grounding block - just connect the third wire there. If the shield is of the old format, it is recommended to call electricians, since it is unsafe to carry out this work yourself.
There is an alternative option when “zero” is used as land. Connect the third wire coming from the bathroom to the “zero” of your network. However, there is a risk that when servicing the shield, the installers will mix up the wires. As a result, the maximum voltage will go to the body - it is dangerous. It is for this reason that you need to call electricians. The work will cost inexpensively, since you have already done the bulk of the work. It is also necessary to put an RCD in order to ensure maximum safety for yourself and your loved ones.
Unsafe grounding methods include connecting wires to water pipes. This method is described above, only a pipe is used instead of the battery - the essence of the work remains the same. The connection area must be cleaned from enamel, and secure the wire with a clamp. It is not recommended to use this method for the reason that during a breakdown in insulation, you can get a shock when touching the pipe. Also, pipes will quickly wear out due to stray currents coming from the machine.

Features of grounding in a private house
The main task is to lay the grounding circuit, which is performed according to this scheme:
- An empty seat is selected on the site;
- It is necessary to make a deepening, the minimum depth is 2 meters;
- Next, a simple metal pin is installed;
- The ground wire must be fixed with a welding machine.
It is worth considering that the earth may be too hard. In this case, an alternative grounding method is used. It is necessary to dig a hole, one meter is enough here. At the bottom, you should put any metal structure and fasten the wire by welding. Usually for these purposes they take backs from old beds.
When to abandon grounding?
Before you start grounding the machine, you need to check if there is a common ground for the apartment. This applies to residents of private and old houses built 50-60 years ago. In newer buildings, grounding is already carried out during the construction of the building. Even if there is no common grounding in the house or apartment, you can make it individually for the most important equipment.
IMPORTANT! You should not worry about the issue of grounding if you live in a new apartment. In new homes, modern wiring is installed, which differs from the old version with a third wire. It is he who is responsible for grounding. Check if the three-wire cable comes from the equipment.
The next step is to test the technique. Inspect the machine for obvious damage. Sometimes such blows are caused by a malfunction inside the machine. For example, if the insulation of the wire is damaged, then a tangible electric shock can be received from the case - repairs are needed here, since grounding will not solve the problem.
Video grounding for an outlet
The most difficult step is grounding the outlet. In this video you will clearly see how to properly perform such work. After studying the instructions, you can understand the intricacies of the process and decide whether to take up this work or not. Grounding of household appliances is carried out according to one scheme, whether it is a washing machine, refrigerator or microwave.
As you can see, the process is quite complicated, so it’s worth undertaking work if there is experience in servicing and working with wiring. In other cases, call a specialist. Remember that there is a risk of electric shock when performing these operations.
