How to make grounding in the apartment

In order to ensure the safety of human life, a specially designed system for earthing electrical devices. By itself, grounding is a ground wire, which in turn is connected to the grounding point and conductor. The conductor is located in the ground. In most cases, a steel or copper rod is used for the conductor. Some experts recommend using water mains as grounding, but this is not a completely reliable method. So, consider in detail how to make the grounding in the apartment independently.

Special features

In most cases, Khrushchev and Brezhnevka do not have a grounding system. The need for grounding arises for the reason that the apartments are a large number of very different household appliances. If you want to protect it from damage, the best option is to make a grounding with your own hands. This will require the following tool and material:

• Packaging screws and washers.
• Several meters of stranded wire of suitable cross section.
• Metal rods.
• Screwdriver.
• Pliers.
• Drill.
• Set of drills.
• Metal strip, the cross section of which should be 50 mm².

First you need to replace the existing two-wire electrical network to three-wire. It is necessary to purchase sockets that are designed for three contacts. As a rule, two-contact sockets were installed in an apartment without grounding. If you are in the apartment completely change the wiring, then immediately run three wires. To connect an outlet with grounding, you must correctly determine the "zero". Accordingly, of the three wires laid, only one wire will be positive. In the process of connecting one neutral wire is connected to ground, and the second directly to the power supply. When all the wires are connected, the ends must be exposed, removing the insulation from them. Further, the vein is divided into two equal halves, between which a screw with a washer is inserted. This wire with a screw must be fastened to a specially prepared place on the shield. In most cases, on the shields, the place for fixing the ground connection is indicated by an appropriate sign, it can be Ground or GND.

If there is no conditional place, then the wire can be fixed to the metal base of the shield.

As a rule, the wire for grounding in the apartment is held for electric ovens, washing machines, bath and so on. For some household appliances and stationary devices, a grounding device is simply necessary according to the instructions. In private houses and cottages make the ground loop. How to make it, it goes on.

How to make a ground loop

The accumulation of static electricity can be not only in very wet areas. Therefore, to make a grounding circuit is necessary to ensure the safety of the electrical system in the house. In addition, not even an electrician can do this. This device is very easy to make: it’s enough to drive several electrodes into the ground and connect them with metal strips.

To ground the house will be enough three electrodes. You can use the crowbar. Previously, it is necessary to cut the threads and drill holes to make connections. The process of manufacturing the grounding circuit is performed in the following sequence:

1. First of all, digging holes for the installation of electrodes. They should be in the shape of a triangle.
2. Electrodes are driven to maximum depth.
3. Small trenches are dug between the three pins.
4. Three electrodes are interconnected by a metal strip.

As mentioned above, the strip should have a cross section of 50 mm². Then the contour is welded. A grounding wire is attached to the contour with a bolt and nut.

Acrylic and Steel / Cast Iron Bath Ground

There is a lot of controversy about whether the bath should be grounded or not. It should be noted that the bath is essentially a potentially dangerous object, so it is best to ground it.

Some throw a ground wire from the bath to the sewer or water riser. But now this technology can fail, for example, if the neighbors on the floor below replace the riser with plastic. For this reason, grounding is best done on the panel, which is a special grounding bus. Consider the examples of cast iron / metal bath and acrylic earthing.

Grounding metal / cast iron bath.

Mainly a hole is drilled in the stem. Then the grounding strap is fastened with a bolt and a nut with a washer.

In modern cast-iron / metal baths, a special petal is made, which is specially designed for grounding. It is very easy to attach a stranded cable.

If electrical water heaters are additionally installed in the bathroom, then they must also be grounded.

Grounding acrylic bath.

If we talk about acrylic, then he himself does not conduct current. But despite this, an acrylic bath can accumulate a small amount of static electricity. As a rule, such baths are mounted on a metal base, which should be grounded.

This applies to the installation of hot tubs. Such devices must be connected to a separate outlet, which should also be grounded. Moreover, these sockets are mounted at a certain distance from the hydromassage: from the edge of the bath 700 mm, and from the floor 500 mm. For security purposes, you can install a separate RCD circuit breaker on the panel, which will protect equipment from power surges.

For grounding acrylic and cast iron / metal baths, use stranded wire with insulation, the cross section of which should be 6 mm.². Grounding points should hide behind a decorative installation, so as not to spoil the appearance of the bathroom.

Ground washing machine

Often when washing the machine can break through the current. Especially often this happens in the process of removing wet laundry from a metal drum.

1. One of the simplest methods of grounding is the installation of a RCD and a potential equalization system.
2. During the assembly process it is important to check the wire for insulation integrity. As mentioned above, it is better not to use plumbing and sewage for the removal of stray currents.
3. When installing electrical wiring, it is recommended to make a separate outlet for the washing machine.
4. Do not use the carrier.
5. To connect electricity to a typewriter, you must use a three-core wire. One of them will perform the role of grounding.

On such tracks it is not recommended to use twists to connect the wires. The wire coming from the machine and to the outlet for the washing machine should be solid.

As for the automatic machine, then for a washing machine it is best to use a power of 45 A. If the socket is waterproof, then it can be put in close proximity to the machine. If not, then outside this room. In this case, you will need to extend the wire from the washing machine to the place of its electricity supply. In fact, this method of grounding those or other household appliances is performed according to one scheme. The most important thing is to properly perform the initial work.

Tips and tricks

Below are the main recommendations and tips for making grounding in the apartment:

• It is recommended to ground all household appliances in the apartment.
• Each outlet in the apartment must be grounded.
• It is not allowed to connect the equipment or grounding of the sockets with the neutral wire when the device is in working condition.
• When connecting the cable, the power must be temporarily disconnected at the distribution board.
• For quality grounding work, special grounding terminals should be used.
