How to make ground in the apartment with his hands

All we constantly use in household electric current. It is so entered into a habit, we click on the button and turn the tumblers, not thinking about what processes occur during exposure to an electric current. But among such processes can be dangerous to humans.

Passing through the body, an electric current produces a destructive effect and can lead to death. So what, you say. I did not stick my fingers in the socket. And this is not required.

What is the ground and why it is needed

Do you ever feel the light "shots" of the electric current running from the washing machine? But this - a consequence only a small break in a moist environment. When the full transition voltage on the housing you will get an electric shock, as if the two took up the bare wire. Or even dangerous, if the floor is wet.

In order to prevent such a phenomenon was coined ground. In most European countries, domestic mains were upgraded even after the Second World War. The Soviet Union did not support the idea, because it was associated with significant costs. In a cheap, prefabricated and mass housing, what were the "Khrushchev", such costs could not be considered.

Those who have been at the enterprises, has seen how powerfully organized grounding machine to the mains 380. This metal lath thickness 3 - 4 mmTo which each device on a bolt or weld secured thick wire or rod. Outside the building the band goes into the ground to a depth of about one meter.

As dispensation ground

Structurally, the earthing system for the house is no different from industrial. Its main task - is to withdraw the stored charge of the electric current, discharge it. Heading into the ground, he disappears without a trace and does not bear any risk. Unfortunately, the wiring in older homes is implemented on the basis of TN-C, which means that from the transformer substation goes 4-conductor cable with one gluhozazemlonnoy neutral.

The apartment is already setting the wiring of 2-wire cable - and zero phase. That is, in such houses is not "earth" to which one could connect the grounding contact sockets. The only option - to make their own arrangements for ground flat.

How to Install a grounding in the apartment

There are two ways to solve this issue. The first way - to work through housing office or management companyFrom which the entire house, or at least an entrance shall be required to install a separate grounding circuit, referring to the current rules of operation of residential houses. The path is long and nervous, even if tenants agree to purchase material for their money.

The second way - self-installation Grounding the apartment. Works that are required for the conduct of, and structures resulting unlikely to provoke a conflict with other residents and to attract the attention of the management company.

Step by Step instructions independent ground installation in apartment

Step 1. You need to make a big deal - reveal all wiring in the walls to get access to all points of electric distribution to consumers, that is, to all outlets. It's best to do it during the renovation. If your wiring is old, change the cable as a whole. It should be trohzhilnym, preferably copper. Cheaper than the cable, the smaller percentage of this copper it contains.

Cheap products omednonnye uses aluminum alloy wires - they have a characteristic reddish color only from above. Plasticity is also less than that of copper. Route the cable from the apartment shield to all current users in the apartment on the available Grooves.

Step 2.Connect the cable to a padded outlets. Red and blue wires are connected to the power contacts are sockets and yellow-green - on the grounding. Then you need a common ground wire from all over the apartment, connected to a visor, take to the streets. This is best done with a single cable thick section in isolation. Alternatively, the steel strip can be used as an industrial grounding.

Step 3. On the street no closer than two feet from the blind area home need driven into the ground rod to a depth 50- 60 cm. Suitable conventional valves. The tire grounding circuit is welded to it.
