Earthing in your house with your own hands: important points

In each house there are networks conducting electrical current, and electrical appliances, the constant use of which causes wear of the wires, sockets, which leads to a short circuit. This can entail not only a breakdown of expensive equipment, but also a threat to life. In order to avoid such consequences, in living quarters and other structures, discharge of discharges of current into the ground is provided. It should be taken into account that in multi-storey buildings these works must be carried out during construction by specialists, since here it is necessary to make exact calculations. And in one-story buildings, you can make a grounding in your house with your own hands, having a basic knowledge of electrical engineering.

What is grounding?

Grounding is a connection of non-conductive parts of devices, usually a housing with earth. This is done to protect people from the breakdown of current and from the accumulation of static electricity. A typical grounding installation includes a contour element consisting of electrodes connected to the ground and a special wire coming from the mains in the house. The tapping of current into the ground is based on the principle of physics, according to which the flow of charged particles goes along the path of least resistance. At the same time, you can ground yourself in your house with your own hands and not be afraid of a current shock and a short circuit when turning on the devices.

Helpful Tips

In order to ground in a private house with your own hands, it may be useful to know the following information:

• As conductive elements and electrodes, it is necessary to choose materials with a conductivity higher than that of the human body;
• It is not recommended to ground the neutral wire, because there is also an electric field in it;
• It is forbidden to cover the electrodes with anti-corrosion paint, since in this case the tapping of current into the ground will not be carried out.

Ground loop

For more complete coverage of the topic "Earthing in your own house with your own hands," it is superfluous to consider in more detail what the ground loop is. This installation of a structure consisting of vertically arranged electrodes to a depth of up to 3 m, horizontal connectors and a cable coming from the distribution board.

The form of the contour can be in the form of a triangle, a square, a rectangle, or simply a straight line. In this case, the contour can be placed around the house or at a distance of 1-10 m. As the electrodes, the most frequently used products are black metal: pipes, corners, smooth-structure armatures or I-beams. The main condition for choosing a material is that the section of the part must be at least 1.5 cm ² .

Order of work

Grounding in your house with your own hands can be reduced to the following order of work:

1. Dig the trench to a depth of at least 80 cm, the freezing point of the soil, according to the selected shape of the contour.
2. Drive parts into the ground to a depth of 1.5-3 m, depending on the location of groundwater;
3. Connect the electrodes with a wire using a welding machine, and place the welding places with a special coating, which protects against corrosion.
4. Route the cable from the power distribution board and connect it by welding in advance to the bolt outline.

In this case, the only difficulty is the replacement of the existing power grid with three wired elements. This requires knowledge of electrical engineering, as well as skills in laying wires. You also need to know how to make repairs yourself with the connections of the sockets. Working with devices that are energized without special knowledge is dangerous, and therefore it is better to contact specialists.
