Where electricity is present, there is naturally a risk of electric shock to a person. To avoid this, insulating earthing of all electrical wiring in the house is always provided. In multi-storey residential buildings, for example, initially all sockets already in the project have a ground wire that is brought out, providing each apartment with sufficient insulation. This point should also be taken into account in cases where an electrician is performed in the country with his own hands.
In other words, it is necessary to create such safe conditions when excess electricity will not “rush” at a person, but will smoothly “merge” outside the house – into the ground.
How to make grounding in the country with your own hands correctly? To begin with, we should recall some physics lessons that talked about ground loops. Some of them are connected by an “asterisk”, others – by a “triangle”. It is the grounding triangle that is the geometric figure that can provide a valuable service to the summer resident. A good thing in the household is a metal detector, yes, yes, the one with which adventurers look for treasures, but in addition, it can be used to determine, for example, an electrical cable laid underground or find keys lost in the garden. View metal detectors at http:///catalog/kontrol-dostupa/metallodetektori/ , you can also place an order there.
The ground loop, of course, will be in the ground. Where exactly, one should not think for a long time – of course, not far from the switchboard. Stepping back a little from the wall of the house, make a markup for the intended installation location of the ground loop.
The vertices of an equilateral triangle are formed using metal rods (pins) about 3 meters long, metal two-inch pipes or corners 5×5 cm in size, which are first driven into the ground for half their length. The distance between the peaks depends on the degree of soil moisture: the higher it is, the shorter the distance. The most optimal option for the lengths of the sides of the triangle is 3 meters.
The connection of the vertices is carried out with metal plates or reinforcement with a cross section of up to 16 mm by welding or using bolts. The plates should be laid in special recesses in the ground, dug to a depth of up to 0.8 m.
So you have a closed circuit that will “take on” excess electricity, isolating you from close contact with dangerous electricity. Now the metal pins (tops of the triangle) should be driven into the ground with a sledgehammer for their entire length.
The “connection” of the ground loop with the switchboard is carried out using a thin metal pond (or the same piece of reinforcement that is used in the loop) using, again, welding or bolting. Do not forget to completely sprinkle the grounding triangle with soil.
To ensure greater “workability” of grounding, table salt should be added to the soil with which the metal pins will be covered. And on hot days, the ground where the circuit is buried should be moistened from time to time with salted water (for a better outflow to the electricity circuit).
As you can see, the installation of grounding is a very crucial moment in laying electrical wiring around the house. And if it will be very difficult for you to make grounding in the country with your own hands, you should not refuse it at all. Because it is a prerequisite for the normal functioning of the wiring.
If you want to avoid a situation where at one “perfect” moment you can be “shocked” by a current, say, a coffee maker or a washing machine, just because you could not install the ground loop yourself, entrust this matter to a specialist. This work will not take much time, it will require minimal cash costs, but you can sleep peacefully, knowing that none of your loved ones will suffer from electric shock.
