Можно ли менять проводку по частям и как это сделать правильно?

10 правил частичной замены электропроводки. Преимущества и недостатки замены проводки по частям.

Далеко не всегда есть возможность полностью заменить электропроводку в квартире. Это связано с материальными возможностями, а также спецификой проведения ремонта. Допустим, если владелец квартиры решил сделать ремонт только в ванной комнате и на кухне, менять всю проводку по комнатам не всегда есть желание. Однако и оставлять старую электропроводку в комнатах, где будет выполнен ремонт, не является правильным решением. Лучше немного переплатить и заменить кабель, а также электрофурнитуру на новую, более безопасную и качественную. В этом случае как раз и применяется частичная замена проводки в квартире либо частном доме. Особенности ведения работ, а также преимущества и недостатки этого метода будут изложены ниже. Содержание:

Стоит ли менять электропроводку частями?

Чтобы было понятно, рационально менять электрику по частям и можно ли так делать вообще, для начала перечислим преимущества такого вида электромонтажа:

1. Меньшие затраты.
2. Скорость электромонтажа нескольких комнат (либо отдельных линий) выше, чем полная замена проводки.
3. Нет необходимости делать ремонт во всех комнатах.

На этом достоинства частичной замены электропроводки заканчиваются. Если говорить о недостатках, их гораздо больше:

1. Соединять алюминий с медью можно далеко не всеми способами и в любом случае такое соединения является опасным. Как мы знаем, раньше вся проводка проводилась алюминиевым проводом, сейчас же нужно использовать медный кабель. Поэтому избежать соединения алюминия и меди при частичной замене электрике невозможно.
2. Сложность соединения новых линий в старых распределительных коробках. Во-первых, в старых распредкоробках мало места для коммутации жил. Во-вторых, алюминиевые провода достаточно хрупкие и могут сломаться при укладке новой линии.
3. Повышенная нагрузка на старую проводку. Если вы просто решите частично поменять электропроводку в квартире либо доме, при этом подключив новый кабель к старому в распредкоробке, может возникнуть перегрузка. Связана она с тем, что к коробке от щитка будет идти старый алюминиевый провод маленького сечения, который скорее всего не выдержит новую нагрузку. В результате придется тянуть новый кабель напрямую от щитка, минуя распредкоробки. А это не только проблематично, но еще и усложняет схему электропроводки.
4. Больший расход материалов. В связи с применением «обходных схем» уйдет больше кабеля на электромонтаж в целом. Да и сами работы будут сложнее и дороже (если воспользоваться услугами специалистов).

Как вы видите, частичная замена электропроводки в квартире и доме возможна, однако она более проблематичная и небезопасна. Низкая надежность соединений, а также высокая вероятность возникновения перегрузки в сети является достаточно весомыми недостатками.

Нюансы частичной замены проводки

В некоторых случаях совсем не обязательно менять полностью всю проводку на новую, даже перед капитальным ремонтом. Чтобы сэкономить на замене проводки, можно на освещение оставить алюминиевый провод, а на розетки и отдельные линии проложить медь. Если старый алюминиевый провод в хорошем состоянии, группу светильников он должен выдержать т.к. их мощность не особо большая, к тому же новые светодиодные и энергосберегающие лампы потребляют меньше электроэнергии, чем старые лампочки накаливания. Итого, замена только силовой линии также может считаться как частичная замена электропроводки на медь.

С розетками и отдельными линиями на мощные электроприборы такой трюк не пройдет. Это связано с тем, что силовая линия обязательно должна иметь заземление, а для этого прокладывается трехжильный провод вместо двухжильного. Поэтому если вы решили, что по аналогии с освещением можно частично поменять проводку для подключения розеток, знайте — этот вариант является недопустимым.

Правила выполнения работ

Чтобы не повторятся и не описываться процесс замены проводки несколько раз, в этой статье мы предоставим лишь ключевые моменты, на которые нужно обратить внимание. Итак, если вы хотите поменять электропроводку по частям в частном либо панельном доме, учитывайте следующие рекомендации:

1. Кабель нужно использоваться трехжильный, медный, с двойной изоляцией. В квартире и доме рекомендуем проводить кабель ВВГнг либо NYM. Для розеток выберите сечение 3*2,5 мм.кв., на группу освещения достаточно будет проложить проводник сечением 3*1,5 мм.кв. На электроплиту можно вывести кабель сечением 4 мм.кв. В любом случае нужно рассчитать сечение кабеля по току и на основании готовых значений выбрать подходящий размер.
2. Розетки и выключатели замените на новые в любом случае. Розетки должны быть рассчитаны на 16А. В ванной комнате и на кухне (рядом с мойкой) поставьте розетки с крышками, чтобы защитить контакты от попадания влаги.
3. Соединять провода разного металла нужно специальными клеммниками либо опрессовкой соответствующими гильзами. Обычные заизолированные скрутки делать ни в коем случае нельзя.
4. Защитить линию от перегрузок и короткого замыкания нужно автоматическим выключателем. От утечек тока защитит УЗО. О том, как выбрать УЗО мы рассказали в отдельной статье, про выбор автоматического выключателя также шла речь. Можно также выбрать дифавтомат, который защитит и от перегрузок, и от КЗ, и от утечек тока.
5. В частном доме обязательно нужно сделать заземление. В квартире не всегда удается организовать заземляющий контур. В этом случае спасет установка УЗО и организация системы уравнивания потенциалов.
6. Обязательно необходимо заменить старые пробки на автоматы, а также старый индукционный счетчик, если его класс точности 2,5.
7. Все работы должны проводится при отключенном напряжении. Если понадобится розетка для подключения электроинструмента, можете запитать ее напрямую от щитка, обязательно отключив все остальные линии.
8. Перед тем, как приступить к электромонтажу, обязательно изучите описанные нами ошибки при монтаже электропроводки, а также требования, предъявляемые к электромонтажу. Информация достаточно полезная и позволит избежать наиболее популярных ошибок, допускаемых домашними мастерами и электриками-самоучками.
9. Чтобы не переплатить и по несколько раз не менять автоматы и основные силовые линии, рекомендуем даже перед тем, как выполнять частичную замену проводки, обязательно составить схему электропроводки, причем не определенной комнаты, а полную.
10. Перед проведением работ обязательно подготовьте весь необходимый инструмент, а также составьте смету на электромонтажные работы. Чем тщательнее будет выполнена подготовка, тем быстрее будет произведен основной процесс. Весь необходимый инструмент изображен на фото:

Учитывая все предоставленные выше советы вам удастся безопасно и правильно выполнить частичную замену электропроводки. Все же после выполнения работ, до отделки стен, рекомендуем пригласить электрика, чтобы он еще раз все проверил и прозвонил цепь.

Напоследок рекомендуем просмотреть полезное видео по теме:

Теперь вы знаете, как организовывается частичная замена проводки в квартире и частном доме. Если вы все же решили поэтапно менять электрику, советуем делать это с небольшим интервалом относительно окончательной, полной замены проводов. Не нужно затягивать с полной модернизацией электрической сети, т.к. старые провода и электрофурнитура могут стать причиной возникновения пожара или же что еще более опасно — причиной поражения током.

Many Russians regularly make repairs in the apartment, but before the replacement of electrical networks, hands do not reach.Everything works fine, so there is no problem, but it’s not. They will appear, but it will be too late. 90003 90002 Replacement of electrical wiring with their own hands will allowsave the family budget and get an electrical network that corresponds to modern electrical equipment, have good outlets and switches in the right and convenient place. 90003 90002 Work to replace the electrical network must becomply with all the rules and comply with modern security requirements. Only then can you guarantee a comfortable stay of the family in this room.90003 90010 Conditions of installation of electric systems 90011 90002 A professional electrician and home technician should know and observe certain requirements when installing new electrical networks: 90003 90014 90015 90002 Replacement of electrical wiring in the apartment is madeentirely. When you change the wires in parts, many unnecessary and unnecessary connections are formed. Old aluminum wires can get micro cracks when bending, and this can lead to their failure, you will have to open the wall and repair it again.90003 90018 90015 90002 Before starting the replacement of the wiring, a plan is drawn uplocation of sockets and switches, lighting devices. The places where there will be energy-intensive devices are determined, separate lines are used for them, so it will not be easy to rearrange them subsequently. 90003 90018 90015 90002 The consumption of electricity per line is compulsory. The power consumption per each must not exceed 5 kW. 90003 90018 90015 90002 It is not necessary to save on the quality of sockets, switches and other small things.The more qualitative it is, the safer it is to live in such an apartment. 90003 90018 90015 90002 Wiring is better to change before the startplastering works. For laying, tubes are used, corrugated or smooth. In the junction of wires, special boxes are installed, they provide free access to them. 90003 90018 90015 90002 Replacement of electrical wiring should follow a simple scheme, which will make it possible to easily carry out the following repairs. Aluminum wiring serves about 30 years, copper longer.90003 90018 90039 90010 Electric wiring of a private house 90011 90002 Replacement of wiring in a private house is not enoughdiffers from the change of wires in the apartment. The difference is that houses are two-story or more. To this, various sources of electrical network connection are added. 90003 90002 Electrical installation of the apartment is connected to the switchboardelectricity, it is located on the staircase of the house, and a private cottage is connected from the power line or from the transformer of the village.The principle of wiring for a private house is the same as in an ordinary apartment. 90003 90002 A scheme for placing all outlets, switches, household and lighting devices is made. Old wiring is dismantled and a new one is installed. 90003 90002 Wiring consists of 2 groups: lighting devices and sockets. Because of this, it is mounted in a room from two different parts. One is responsible for lighting devices, the other for sockets. The load on the network will also vary, so the wire is often used differently.Using two wiring simplifies repairs in the event of an accident. If lights stopped working in the evening, you can turn on additional ones by using a power outlet. 90003 90002 Replacement of electrical wiring in the house can be openor hidden, it all depends on the material from which the house is made. If it has several floors, then everyone should be connected separately. It is desirable that each room is connected separately and has two automatic machines. One is responsible for the sockets, the other for the lighting fixtures.With this connection scheme, a short circuit in one room does not affect the supply of electricity to other rooms. 90003 90002 According to the instructions, all modern devices must beare grounded, therefore in the private house it is necessary to have a good grounding circuit. The electric cable in such possession is carried out in a vertical or horizontal direction, it is not necessary to be carried away by loops and bends, they are inadmissible. 90003 90010 Replacement of electrical wiring in the apartment 90011 90002 Many Russians are reluctant to take such a step asreplacement of old electrical wiring.Only a desperate situation makes them do this work. It is worth noting that the timely replacement of electrical wiring allows you to protect your home from many problems. 90003 90010 Electric wiring replacement project 90011 90002 When replacing the electrical wiring, remember thatall must be made according to the requirements and standards required for the installation of electrical networks in the apartment. The main thing to do first of all is to calculate the future consumed load of all the electrical equipment of the apartment and select the appropriate electrical cable.90003 90010 Preliminary work 90011 90002 Initial calculations: 90003 90014 90015 90002 For energy-intensive devices, plan a separate line that can withstand the maximum load. 90003 90018 90015 90002 Choose the most convenient locations for outlets and switches. 90003 90018 90015 90002 Pick up lighting fixtures for all rooms in the apartment in advance. 90003 90018 90015 90002 Calculate the energy consumption that will beconsume all electrical appliances and equipment installed in the apartment.This is easy: each device has a passport, where the necessary parameters are specified. The total flow should be increased by some amount (in case other electrical appliances are added). 90003 90018 90039 90002 To avoid possible errors, consult a specialist. 90003 90002 Replacement of electrical wiring in a panel house is carried out in two ways. 90003 90014 90015 90002 Remove the old plaster, remove the worn out wiring and lay the new one in the freed grooves. 90003 90018 90015 90002 Leave the old wiring in the walls, and for the new make grooves and put the cooked cable in them.90003 90018 90039 90002 Preferably the first option. This will avoid mistakes, the old wiring was mounted according to all the rules and was adopted by a special commission. 90003 90010 Acquisition of the necessary equipment 90011 90002 Work should be started only after there arepurchased all the necessary instruments and small things. Do not save, buy only quality equipment. It will be located in places, access to which is difficult, there is no permanent control over them, so there must be confidence in their efficiency and technical serviceability.90003 90002 To work on the replacement of electrical wiring you will need: cable of the required cross-section and length, pipes for laying in them wiring, devices for distribution and switching of wiring, sockets, switches, the necessary tool, allowing to make work qualitatively and quickly. 90003 90010 Choice of instruments and materials 90011 90002 The first step is to determine which cable will be used — aluminum or copper. You can use both, but copper has better technical characteristics of electrical conductivity.90003 90002 The choice of cable cross-sections is best entrusted to specialists, they will do it more professionally than the home master. 90003 90010 List of works when replacing the old cable 90011 90002 The replacement of electrical wiring in a Khrushchevka does not differ from the order of work in an ordinary apartment. When replacing the old cable, use existing and newly laid grooves. 90003 90010 Arrangement of new wiring 90011 90002 Work to replace the old internal electrical networks in the apartment is divided into several stages: 90003 90014 90015 90002 Old ones are cleaned and new channels for electrical wiring are being prepared.90003 90018 90015 90002 The places where new switches and sockets, distribution boxes will be located are deepened. 90003 90018 90015 90002 Installation of wiring. 90003 90018 90015 90002 Installation of the switchboard. 90003 90018 90039 90002 Old channels are cleared, and new ones are preparedwith the help of shtroboreza, Bulgarian. Work better in the respirator and earplugs, so the respiratory organs will be protected from dust, and the ears — from strong noise. The work is dirty, try to immediately remove the concrete crumb and dust.An excellent assistant in this you will be a vacuum cleaner. 90003 90002 After the channels, grooves are prepared fordistribution boxes, sockets and switches. To perform this work, a perforator with various nozzles is used. At the end of the recess, they are cleaned of dirt and dust. 90003.90000 How to Replace the Wiring on an Old House | Home Guides 90001 90002 By Charles W. St.Clair Updated December 09, 2018 90003 90002 Replacing electrical wiring is part of making an old house safer, more modern and more livable. The approach you take will depend on your budget, your ability to access the walls, attic, and crawlspace and the level of demolition allowed. This kind of remodeling is easier to do in a newly purchased home than a well lived-in one. Do not attempt to replace your own wiring unless you are experienced in electrical construction.90003 90006 Permits and Codes 90007 90002 Rewiring a house will require a permit from your local building department. Homeowners are allowed to do electrical repairs on their own houses, but the work will have to be inspected. You may want to consider hiring an electrician to advise and assist you with planning and discovery, since understanding the wiring of an old structure involves a good deal of experience and knowledge. 90003 90010 Accessing the Walls 90007 90002 The first step in replacing wiring is deciding how much you will access the walls.If your house is newly purchased, before you paint or move in, plan on cutting numerous holes in the walls to make running the new cable easier. If your house is lived-in, or you do not want to cause a major disturbance, the task will take much longer and your options will be limited. You may have to leave the wiring in the walls intact and only replace the cable in the attic or crawlspace. 90003 90014 New Cable Locations 90007 90002 The majority of the new cable will likely be run through the attic and crawlspace before it enters the walls.Where you run the cable depends on your ability to access the spaces, but generally outlets are fed from below and wiring for lighting is fed from above. Be careful of hazards such as asbestos and fiberglass insulation, as well as the old wiring. Make sure the power is turned off before drilling new holes and cutting into the walls. 90003 90018 Rewiring an Outlet 90007 90002 To replace the wiring feeding an outlet, the old outlet needs to be removed. It may be possible to pull the old cable back through the hole in which it runs.However, if it is stapled in place, then that is not an option. You will have to drill a new hole for the new cable. 90003 90022 Drilling New Holes 90007 90002 If you are refeeding an outlet or a light switch and you can not reuse the old cable’s hole, a new hole is necessary. Although it requires a fair amount of skill, new holes can be drilled from inside the room with a flexible drill bit. Alternately, accessing the crawlspace or attic and drilling through the wood plate is necessary. Locating your hole involves careful measuring.Drill a 1/8-inch hole first to make sure you are not about to drill a hole through your floor or into a stud. 90003 90026 Determining the Number of Circuits 90007 90002 Often old wiring does not provide enough circuits for the energy demands of modern appliances, lighting and technology. Before you start running cable, you must plan your circuits according to the rules of the National Electrical Code, or NEC. The NEC gives guidelines that must be followed, especially for spaces such as the kitchen and bathroom.Do research on housing circuits to help plan your layout, or hire an electrician as a consultant. 90003 90030 Replacing your Service Equipment 90007 90002 Besides replacing the wiring, you should also consider replacing your electrical service, which includes your main panel and any subpanels. This may be necessary if your old panel does not have enough room for the circuits you have added. Also, it may be advisable if your old panel is in bad condition or if you have fuses instead of circuit breakers.If you upgrade the panel, you will likely have to replace the wires that feed the house. This job is best left for a professional electrician. 90003.90000 Replacement of electrical wiring in a private house.
