Electric appliances in a modern house are familiar and obligatory things, which obliges the builders to ensure grounding at home – this will warn electric shock. Otherwise, if for any reason the voltage enters the case or any other parts of the electrical appliance, not intended for this, then the use of such a technique becomes deadly for the consumer. To prevent this from happening, the rules for the installation of electrical installations make a protective ground for a prerequisite for the electrification of the building.
Grounding can be protective or working. Work ground is required for the work of a professional level, while for an ordinary consumer it is enough to have a protective ground. In the old private sector, the power networks of which are not designed for intensive electricity consumption and a large number of household appliances, grounding may not be completely absent – it was not mandatory before. The presence of grounding in such a house should be convinced before the operation of modern electrical appliances. If it is not, then it is necessary to make it yourself or using the services of employees.
To ground the house, it is necessary to first find out which of the grounding systems was used in the line of connection to the central communications. If the system was created for a long time, then, most likely, a four -core cable was used to perform a three -phase system, for a single -phase, a two -core cable was used without special core for protective grounding. In most houses of the private sector, the 0th vein was grounded at the source of electricity. In such a situation, you will need to remake the wiring and circuit of the house of the house. If there is no ground core in the structure of the electric wool cable, then zero core in the introductory shield is split, the connection is performed to the 0th and grounding tires united in one.
If the energy supply system boasts the presence of specialzhils for protective grounding, then you can perform grounding with working and protective 0 guides. Alterations are carried out only inside the house, zero and grounding veins are connected to the corresponding tires, they are not connected with each other. In this case, all sockets should be with grounding.
