How to make a secure grounding in the apartment ?

right decisions

method №1- Connecting the RCD

If the ground is not flat (not provided by the developer), and you still want to protect yourself from electric shock, the best time to connect a residual current device (pictured below).The whole problem of this unit is, of course, not solve, but still with the leak currents it served to instantly turn off the power unit - washing machine, water heater or outlet group.

addition, we recommend you to replace the wiring in an apartment in the new - three-conductor wire.In the future, when your time comes to make an entrance ground, you will already be prepared, and all that remains - to hold and connect the PE wire to the corresponding bus floor panel.

Method №2 - Mounting own circuit

frequent in recent cases where residents of panel houses decide to make their own ground in the Khrushchev, which organize individual ground loop.The idea is that from the apartment to the basement extends solid PE conductor on the risers.Near the house is driven at least three metal parts or electrodes, connected by a plate made of metal.To ready the protective triangle (given in the diagram below) spent connected to the wire floor, the other end of which is attached to the body panel.All that remains - to ground the shield and apartments, as you know, leakage protection is ready!

Please note that to make such a ground with their hands only after consultation with the event management company.Spontaneous acceptance of this decision may entail a lot of problems, becauseYou, however as to interfere with the approved project, and if there is some sort of accident, it is possible that it is you yourself extreme.

I would also like to add that if you do decide to make your own ground loop in the apartment, the PE wire must be copper, cross-section of at least 4 mm.kv.Suitable this way of protection, not only for the residents of the first floor, but also for all the others - 4th or even 5th.

dangerous variant of protection

Some would-be electricians decide to make ground in the apartment, just by connecting the third wire to the water pipe or heating system, passing through the room.In no case do not use this option to earth loops asin this case, the picture is as follows:

• current breakdown occurs in the body of the appliance (boiler or washing machine in the bathroom);
• dangerous current transfers to battery and risers hot / cold water, not only your apartment, but all the neighbors, sincea single system.
• victim can be anyone who currently decide to drink water from the tap or simply touch the metal pipes.

way, the rules of the SAE this time agreed and also strictly forbidden, according to the SAE 1.7.110.

1. Mix in zero outlet with a ground conductor (the so-called neutral).If you suddenly will break the neutral wire in the network, a hazardous voltage switch on the body of all appliances connected to the ground flat - computer, water heater, refrigerator, etc.
2. consistent electrical ground (of each other).If you decide to make a ground loop, you know - electromagnetic incompatibility can occur in the event of an accident.As a result, the power plant would interfere and there is a high probability that the ground loop will not prevent electrical shock.
3. Connecting to a bus terminal PE multiple wires.Each pad is allowed to connect one conductor.To neglect this rule is strictly prohibited.

That's all you need to know about how to make ground in the apartment, if it is not.We still strongly recommend using an RCD, as a temporary way to protect, well, insist that the city authorities have taken care of upgrading the wiring in your home.
