What is different from the protective earth ground ?

main differences

Both the first and second protection system performs the same function - to protect people from electric shock when you touch the bare wires or appliance for which there is leakage current.The only difference is that the vanishing triggers immediate power outage at risk of contact person and wires and immediately removes dangerous ground voltage to the ground.This is the total difference from each other.

If we consider the matter further, it is necessary to dwell on what principle of protection in each case, on what basis will be immediately visible difference alternatives.Ground works in the following way: to the body of dangerous electrical appliances and household appliances is connected ground wire that goes to the appropriate bus in the control panel.From there a common ground wire goes to the main earthing circuit - metal structure embedded in the ground next to the house (as shown in photo).If there is a breakdown of the current on the housing or the contact with the exposed current-carrying conductor, danger is over man.

As for vanishing, it represents the connection of the appliance body with a neutral wire network - zero.The result is a closed loop, as shown below.If a dangerous situation occurs, a short circuit and circuit breakers on the opening panel to instantly shut off the electricity. clearly see the difference between zeroing and grounding you to this scheme:

hope now you became clear the differences between the two protection systems and last but not least - how they work.We also recommend you see the difference between them in a visual way of example:

Which is better?

that you fully understood the materials for beginning to give differences in the use of each system, based on which and draw their own conclusions.

• Grounding home can easily make your own hands, having at hand welding machine and a little bit of metal.At the same time to create a vanishing require specific knowledge related to the calculation and selection of the optimal point of connection wire to neutral.
• If there is a broken neutral conductor in the distribution board, the vanishing of the system will not work, and you can become a victim of electric shock.In this regard, a system of protective grounding easier becausein contrast to the PE ground wire is not otgoraet and practically does not fall off, if at least once a year to tighten the terminal.Although this can be said about that the circuit "ground" due to the fact that in the street may also be damaged over time, particularly at the welding electrodes.Again, if you do an annual audit will be no problems.

On this basis, it is possible to make such a conclusion - proper grounding in a private home is not difficult to make your own hands, and besides, such a system more durable, and therefore safe.With regard to zeroing, to create it need a challenge to master, and at the same time, more frequent inspection of the integrity of the neutral conductor, which is a huge disadvantage when comparing the differences.This option is recommended only if you live in the old Khrushchev and "ground" circuit you simply do not have.We hope that now you understand what the difference is vanishing and the ground as the two systems work and how more effective for houses and apartments.
