Grounding and vanishing fundamental differences between them and that it is better to use in the home

Probably most of you have heard about such a thing as vanishing and even more about the protective earth. And you know how they differ, and that it is better to use in the house? If not, then in this article I will explain the fundamental difference between the two systems and will tell that it is desirable to use in your home.

What is the difference

Protective earth is intended to prevent human exposure to the dangerous values ​​of current leakage occurs at. Simply put, if the housing of the electric current of the device appears, it will immediately go to the ground and the person who touches such a device will not be struck by the current.

And you can realize the ground with his own and without major financial outlay. Indeed, it suffices to take the welding machine, a shovel, a few fittings, metal strip and the copper wire. And your circuit will be ready. Then connect it with three wired network your home and all, protection is provided.

A vanishing compound is ground with the working zero. In the case of such insulation breakdown causes a short circuit and thereby disable circuit breakers.

And perform vanishing in the house without having to call a specialist shalt calculates and selects the specific point, it is simply impossible.

For clarity, look closely at the diagram illustrates the difference between the vanishing thereof and ground in a simple manner.

What to choose for the house

Here I say, and will outline its position: I am categorically against the use of zeroing, as this method - it is potentially delayed danger. After all, even if you will very carefully and regularly check the integrity of the ground, there is still a the likelihood that as a result of unforeseen circumstances, will have to change the phasing and zero will phase. In this case, absolutely all appliances, stuck in the network will be under stress, and it can bring to very unfortunate consequences.

The same could be lost zero, in which case the system will be incapacitated, you will once again threatened with electric shock.

Protective earth in this regard several orders of magnitude more reliable and will carry out an audit of bolting enough no more than once a year. And for many years, you will be provided with reliable protection.

Output. If you have a two-wire system, do not try to implement the vanishing, but rather change the wiring on the three-core. If for any reason you do not yet have such a possibility, it is better to put the two-wire network RCD.

Thanks for attention.
