How to divide the PEN conductor according to the SAE ?

Detached house or cottage

owners of private houses in this area was more fortunate, inexpensively cottage owner can make ground at homewhat we described in our article.And perform advanced secure power system in your home.

No matter three-phase (four cores) or single-phase input (two wires), you went to the PEN, it is possible to determine the phase indicator Indicator screwdriver.Further, the opening panel, neutral conductor is connected to the distribution terminal.With it goes to zero, and a separate bus terminal jumper lands, and with the outer contour of the grounding wire connected to it.Place separation PEN conductor can be seen below:

so you know how to divide the conductor, a little present rules SAE Chapter 1.7 (Grounding and protective security measures) and 7.1 (safety precautions):

1. Separation of PEN conductor is madebefore the opening of the switching device (the wire is put directly on the separation of the tire PE and N, which are pushed to separate terminals).In other words, the combined conductor is to be divided up to the counter, rather than after, asintroductory machine according to the rules set for electricity meters.
2. Wire PE should be the same as that of N.
3. forbidden to combine the protective and neutral conductor later in the scheme, the splitting point.
4. Do not use a common bus to rasklyucheniya N and PE conductors. necessary as shown in the photo:
5. advisable to make the re-grounding conductor to the PEN input.
6. Use of switching devices in the chain of PEN and PE conductors.

Apartment

apartment owners are out of luck in this respect, as the organization of the system TN-C-S.The specifics of the supply of apartment houses of the old fund, PEN conductor connection takes place alternately, from floor to floor.And in case of an accident, such as burnout in the neutral conductor floor panel, the apartment comes two phases.In this case, our system stops working and becomes dangerous.

For this reason, the division is prohibited PEN conductor to PE and N, as in the case of an accident the protective conductor is live.

To establish a secure power supply in an apartment, you need to set the plate registration:

• voltage relay;
• RCD or differential automata;
• organize a full grounding device adjoining the garden or the additional cable to the PE obschedomovyh ASU;
• make potential equalization system.

draw your attention to the fact that it is prohibited to use a protective ground water pipes, heating and gas pipes!

In that case if you still have time to do in the flat wiring with protective conductor, before reading this article, we strongly recommend not to switch it to the neutral conductor and access a shield, and leave not connected, as long as your entrancewill do the reconstruction of the wiring and replace the old wiring produce from TP according to the new standards.
While that may use additional security devices described above.

The new apartments to the earthing system TN-C-S separation combined conductor to the neutral and protective earth is produced in MDF.From it are already two wires separately to the floor panel in the apartment, as shown in the diagram below:

Finally recommend that you review useful videos on the subject:

That's all that I wanted totell you where the separation must be performed on a PEN conductor PE and N according to the rules of the SAE.Once again duplicate the response to you will surely be remembered: in private homes wire should be separated to the counter before the introductory switching device, and in the apartments is done in the main switchboard.
