Immediately I would like to note that in this article we consider only one of the optimal wiring options for rooms. In reality, you can completely modify the project, relying on such factors as: the total load from electrical appliances, the number of rooms, the desire to save electricity, etc.
We also bring to your attention a typical wiring diagram in the house: 
As for the components of the wiring, we recommend using the following:
- The electricity meter is a one-tariff meter.in most regions to use multi-tariff items there is no sense because of a small difference in the daily and night rates.
- Single-phase network, becauseeven in modern private houses it is used 220 V, and not 380. Do not listen to those who say that they say to use a three-phase network is necessary because modern household appliances are very powerful. On the contrary, the trend is towards saving energy and, accordingly, producing low-capacity equipment, but at the same time, high productivity. In addition, if you choose the cross-sectional area of the cable in a thicker way, you can use a simple single-phase wiring connection, even for powering powerful equipment. Cable around the house must be copper, it's best to buy VVGng. The appropriate option is selected after calculating the cable cross section for power and current. Usually, a conductor with a diameter of 1.5 mm.sq. is chosen for the fixtures, 2.5 mm.sq. on the sockets, and 4 mm.kv. on the electric stove or boiler.
- The number of outlets is counted individually for each case, so on the electrical wiring plan in the house we indicated one outlet for an example( actually there can be any other number of bulbs).It is recommended to create several rosette groups throughout the apartment building on the assumption that during the repair it will not be necessary to leave the whole room without light. The same situation with lighting - there is a desire and possibilities, create several highways in an electrical circuit, each of which will serve 2-3 rooms.
- At the input, immediately after the electric meter, set the circuit breaker to 40 A( or even 32 A), which is enough even if you use electric heating. As for the other machines, for the outlets they can be designed for 25 A, and for the lighting group by 10 A. In a good way, you need to calculate the current load on the house and choose the most suitable characteristics of the circuit breaker. Sockets must be protected from current leaks by a protective shutdown device or by a diafi-automat.
- Next to the country house there is a garage, which is also powered from the home entrance shield. The wiring diagram in the garage was discussed in detail in the relevant article.
- For power supply from the street, an armored cable AVBbShv is installed, which is laid in the ground without additional protection. With the availability of money, you can buy a more reliable and durable option - a cable VBbShv, whose difference in copper performance lived.
- In all rooms it is better to use LED lamps, becausethey are more durable, consume a minimum of electricity and at the same time can be used absolutely in any room, at least in the bathroom, even in the kitchen, not to mention the bedroom.
- For the bathroom there is a separate outlet group, protected by a 10 mA RCD( other sockets can protect the RCD at 30 mA), which is associated with an increased risk of electric shock( the room has a high humidity).
- Earthing is present, we did not show each individual conductor on a typical wiring diagram( phase, zero, ground), so as not to clutter the drawing.
In the event that you decided to make a wiring diagram in a three-phase house( for 380 V), you will have to choose other network elements according to the characteristics, but the principle of cable routing around the rooms will remain the same.
We draw your attention to the fact that in a wooden country house( usually a dacha option), the electrical scheme will look different and the network elements will be different, which is connected with the requirements for fire safety!

Now you know how to make the wiring diagram in the house with your own hands! If you have any difficulties with the design, at any time send a photo of your homemade plan so that our specialists can consult and help. For this, we created a category "Question-answer", in which we recommend you to participate actively!
