Grounding installation: individual circuit and grounding in the apartment

Most construction companies provide the tenant with an unequipped living space, referring to the fact that the owner is given the opportunity to arrange comfort in his own way and think over the design. Of course, in such conditions, electrical safety is not provided, and, therefore, you will have to carry out the installation of grounding yourself.

If you delve into the essence of the proposed rules, there is nothing difficult in installing a grounding device for housing. All that is required from the repairman is diligence, strength and small waste.

This question is characterized by an accessible answer. Grounding is a protective device that protects a person’s property, as well as himself, from danger from the electrical network, namely, it prevents electric shock and breakdown of household equipment.

Installation of grounding to the shield

There are several varieties and systems of construction, and each has its own detailed rationale. You can get acquainted with frequently used grounding systems in our previous article.

It is quite simple to arrange a protective mechanism for electrical installations, however, if you are new to this business and do not have the skills to work with equipment of such importance, it is better to contact the special service.

Do-it-yourself installation of a ground loop

The installation of a grounding structure is an important step leading to stable operation of the protection of electrical equipment. Therefore, you have to use the exact instruction:

  • first of all, we recommend creating a drawing plan, which will indicate all dimensions, parts used and the location of the ground loop;
  • from this moment we begin to transfer the project to the terrain, that is, we prepare the soil, choose the one that has the least resistance in relation to our future construction;

Important! For places with high resistivity, appropriate types of grounding are used.

  • swarm trenches with optimal dimensions. Here it is recommended to build on the obvious properties of the soil and the season of work;
  • we decided on the previous stage, now we take the appropriate material and begin to design the structure;
  • we hammer metal rods into the ground, connect horizontal electrodes to them and fasten the structure with special terminals. We attach a conductor leading to the main shield to one of the corners of the resulting figure, connect it and perform a functionality check;
  • If the resistance value does not exceed 4 ohms, then the installation work is done correctly.

According to the proposed method, it is easy to install grounding in a private house, and if you live in an apartment, and even on one of the last floors, there is a slightly different installation principle.

How is the ground connected to the outlet

How to create grounding in an apartment?

In old apartment buildings, TN-C grounding systems are found or not found at all. In two cases it is equally difficult to carry out grounding. And what now, to resort to the reconstruction of the entire electrical network? Of course, everyone will decide for himself what to do in the future. In the meantime, we will analyze a few simple ways to make it safe to use an electrical circuit in conditions where grounding is not provided.

Method number 1

In the absence of protection, the installation of grounding devices can be excluded, instead, install a residual current device (RCD). It is impossible to solve real problems with electricity when installing this device, but it is quite possible to save a person’s life and prevent the ignition of electrical appliances due to current leakage.

Method number 2

This option of protective measures provides for the installation of an individual ground loop. It can be done in the cellar or basement. In this case, it is enough to build a structure taking into account all factors and stretch a metal conductor to it from the apartment shield.

Grounding check

Important! Independent construction of the structure must be agreed with the company that manages the development. Otherwise, you will be charged a fine.

A similar method of protecting electrical installations in apartments is suitable for all floors.

What grounding is considered dangerous?

Some inexperienced electricians make mistakes when arranging grounding right in an apartment or house. In the following situations, the device will not only not protect you, but can also harm you:

  • grounding should not be done, for example, directly to pipelines, since in the event of a breakdown of electric current to the case of one of the devices with damaged insulation, voltage will be released to the pipeline, and this is dangerous if a person is nearby;
  • high-voltage voltage will certainly come not only to your pipeline, but is also able to switch to neighboring apartments;
  • can fall under the passage of current and other undamaged appliances in the house.

Important! The PUE states that it is forbidden to connect the ground conductor to pipelines and other metal in the house.

In addition, instead of grounding, many people use zeroing, and this is just an indirect kind of "earth".

Grounding installation scheme for a private house

Creating grounding at home should be considered, because there is a risk of death of your loved ones and children.

How to connect the ground to the shield?

Powerful electrical installations used by a person must be grounded, and any grounding is led to the main electrical panel. In any of these shields there is a panel with many terminals. Wires are threaded into these terminals and fixed mechanically, that is, they are screwed with fasteners.

Before connecting the ground conductor to the terminal in the shield, you must make sure that it is connected to the external ground loop.

Important! Connecting the ground to the shield without an equipped circuit, it is dangerous to ignite the electrical wiring.

We protect electrical appliances from overcurrents

Grounding rail

Household appliances have long been a convenience in our home, which is why we so often think about their safety. Every modern appliance has an equipped grounding plug, and such devices require a special socket with metal grounding terminals. But the use of such devices requires responsibility in the installation and a special technique.
