How to make the ground connection in the apartment

So you've decided to alter the wiring in an apartment with two-wire to three-core, but in a board where your installed electricity meters, there is no corresponding ground bus. So, to give up ground. In this article I will tell you how to properly get out of this situation.

The problem of lack of grounding bus in boards with metering devices is quite acute in prefabricated houses and so-called "Khrushchev". Since they were built in a tight economy of resources.

That is why in these homes wiring is a two-wire system. This means that while there was no need for a protective circuit and grounding systems.

But things are changing and now stands at the heart of it is safety.

How to do it right

To protect yourself from electric shock, the only solution is the following: is the mandatory installation in the switchboard RCD

And implementation of individual earthing circuit.

Important. If about the installation of an additional relay in the control panel you nothing nobody can say that here implement ground loop can be only after you get permission to do so from the management company.

The most common embodiment of the grounding circuit is shown in the picture above, but it should be to stretch Copper is desirable solid wire section of at least 6 square millimeters aforesaid fits securely bolted to circuit.

A plate is attached to a ground bus.

Only such a comprehensive solution will allow you to protect against electric shock.

What is strictly prohibited

Now let's look at ways to discharge the same, I would have never done in my house

vanishing

Some masters are invited to advise you (to save) to perform a so-called neutral grounding - earth connection to the neutral conductor.

This method is dangerous because in the case, if the neutral wire otgorit, then absolutely all the housing appliances included in the vanishing of the network will be under stress. And in the case that if you touch the body, you get hit by the current.

Grounding metal pipe heating

So, if you offer, rather than a single pull wire from the grounding circuit to the shield, connected to the heating system, refuse such an offer.

And here's why: it happened that, for example, your boiler broke down and there was a breakdown of insulation and a current hit on the body. Since you are grounded to the tube, then the current that flowed to the body will go into the pipe. And if at that moment someone decides to have a drink of water, or simply touch an unpainted tube, get an electric shock, which can lead to very dire consequences.

So, we have examined the correct grounding system in the apartment and how to do strictly prohibited. I hope this article will help you. Thanks for attention.
