How to replace the electrical wiring in the apartment ?

Step 1 - determine the scope of work

first thing need to start - you need to determine whether to change the line completely or only certain areas.Here, of course, up to you, but we can say with confidence that the construction of the 60s used to generate power aluminum conductor cross-section of small, probably without ground.This option is extremely dangerous and not even subject to a partial recovery, so it is a time to completely replace the wiring in an apartment with his hands and be calm.

If the conductors in such a state, it is necessary Apartment wiring change:

You should assess their strength and decide on their own whether a replacement will be carried out wiring in an apartment or vse-taki call specialist required.There is already a stick with two ends.On the one hand, there is much difficulty in the wiring line, but on the other hand require special tools, calculations and certain skills of work with electricity.If you still want to try their hand, then we will describe in detail all the stages of work.

immediately recommend that you review the steps to replace the wiring instructions video:

Step 2 - Identifying with the scheme and materials

now go directly to the settlement work.To get started you need to create a scheme which will indicate the place of installation of new switches, sockets, distribution boxes and powerful home appliances, which will be powered directly (for example, electric stove).

Recommended before replacing the wiring diagram view in a studio apartment, which provided the simplest version of the output light groups and outlets in all the rooms.Next, on the basis of the scheme is necessary to calculate the amount of material, while choosing the most suitable characteristics.

Immediately it should be noted that the apartment is used flush mounting, due to the many nuances: electrical safety, impact on the interior of the rooms, fire, etc.At the same time replace the wiring in an apartment with his hands in the open, no one forbids, it all depends on your preferences and effort.

recommend the following guidelines to make the change correctly:

1. cable - copper, three-wire, cross-section of at least 2.5 mm2 for the female group, 1.5 mm2 and 4 mm2 luminaires for high-end appliances.We recommend to carry out the calculation of the cable cross-section to pinpoint the appropriate conductor diameter.As for the brand, it is better to give preference to expensive foreign NYM product labeling.From home, which is cheaper, use VVG or PVA.
2. protective equipment.Without it, can not do, becausesure when replacing the electrical wiring in the apartment need to protect the wiring from the leakage current, short-circuit and overload.For this purpose, the RCD and the circuit breaker (or the combined model - Emergency circuit breakers).Automatic RCD and have different characteristics, which are selected based on the load line.For example, for a two-bedroom apartment, on the outlet group decided to install automatic protection to 25A, for illumination - 16A, to a powerful electric stoves - 32A.Introductory circuit breaker at the distribution board should be designed for 50A, and the residual current device to 63A.From manufacturers recommend to give preference to the leading companies - ABB and Legrand.
3. Junction boxes for apartments are selected on the basis of branching groups and cross-section of all the conductors.Rectangular and square boxes more spacious, but the round is much easier to install.
4. Sockets must be earthed for protection of children, purchase products with special shutters that prevent foreign objects inside.Pay attention to the labeling of products that could withstand the socket load current, or problems in the future can not be avoided when connecting a powerful appliances.
5. to the switch are no special requirements, the main thing that they were comfortable and safe.Among all types of light switches are popular keyboards and dimmers.
6. Connection lived Perform terminals WAGO, today it is the most simple and effective way to connect wires.Besides crowbars are inexpensive.

counting the number of materials and choosing the most appropriate models of products, the list go to the store to shop, and then proceed to the replacement of wiring in the apartment.

Step 3 - Disassemble the old line

Now you can replace the old wiring.To do this, be sure to disable the electricity entering the apartment, we remove all interfering furniture and begin to destroy the finish of the walls.

Replacing the wiring in an apartment provided from distribution boxes in each room.Discover the power "points" can be on the plastic cover on the wall or stand out through the contours of the wallpaper.The lid is twisted, then twisted all disconnected, and the old cable neatly freed from plastered Stroebe.Also, find a wire in the wall, you can use a self-made metal detector, which is created from the available tools in minutes.

draw your attention to the fact that in some places the line can not be removed from the wall without significant structural damage.In this case, you can do without shtrobleniya if the problem area to crop, and carefully insulate, leaving the old Stroebe!

Step 4 - Place the new wiring

Now the most important thing - you need to replace the wiring in your own apartment with a new, more reliable.To do this, we recommend creating a new deepening in the wall that already do for themselves comfortable accommodation of switches, sockets and other network elements.

We will not dwell on this point, sincedetailed wiring in the apartment we looked at in the corresponding article.

When replacing the residential wiring is complete, you must be sure to take a picture of the wiring cables on the walls.This is done so that when problems arise, you can easily find the damaged area on the photo.

obscure Stroebe solution take the time to do it is necessary after all wiring is checked for serviceability.

Step 5 - Verification

And last but not least, the event - new wiring continuity in the multimeter flat.This unit will determine the performance of wiring and a short circuit, if you suddenly something not connected.If the instrument is not revealed errors, then you can connect a ready line to an electric junction and check the operation of all fixtures, switches and sockets.

If all circuit elements work, turn off the electricity again and go to a smearing of cutting grooves.This replacement of electrical wiring in an apartment with his own hands is completed.As you can see, the event is quite time consuming and requires skill, but still with a great desire and care can independently carry out wiring!
