Changing the electrical installation of a home can seem unnecessary, very complicated or, simply, an annoyance that can be overlooked. But in many cases this is not the case. Sometimes a change in the electrical installation is not only recommended for what it may entail in terms of improving its operation. Also of your safety
In effect, as soon as an electrical installation is old enough, it becomes obsolete. Three or four decades ago we did not have so many electronic devices to plug into the electrical current. Therefore, today, installations need a level of power that they did not have before. As a result, the installation works in a forced way, and may have occasional failures.
In addition, these facilities will also be obsolete in terms of approved regulations. And of course, the older the wiring, the more worn it is, which can cause problems. Not exactly working. Bad wiring can cause short circuits, fires, etc. Therefore, the best way to avoid it, if it is suspected that the wiring of a home is 25 or 30 years old, is to study its replacement.
Change the electrical installation: when to do it
The best time to carry out the change of an electrical installation is when a reform is made. Either a whole house or an office or just some of its rooms, such as the kitchen or the bathroom. Because the change can be made of the whole house or only of some rooms.
The main reason for this is that, unless the contrary is decided for any reason (style of the house, comfort, etc.), it will be necessary to cut the new cables in many cases. Or lift the skirting boards and run the cables underneath. Of course, it will only be necessary to do so if the installation is really old.
Especially if the tubes inside the wall that the tubes go through are the ones that were used 30 or 40 years ago. We are talking about the so-called Bergman tubes, cream or yellow. These cables are the ones that were used then to house the cables of the electrical installation. But not anymore, because it was proven long ago that they are conductors of fire. A real danger in case of fire.
In that case, it is convenient to remove not only the electrical cables. Also the tubes through which they go. And then change them for other insulators and that are free of halogens. Once this is done, the cables can be passed through the new tubes without problems.
More changes to the installation
During a reform, other issues can be assessed. For example, if it is convenient to replace the plugs, or install new ones. Or add several to those that already exist. It is common for houses with an old electrical installation to have fewer plugs than are needed today. As a result, a power strip is often connected to sockets. In this way, more devices can be connected to the network at the same time, although it is not the most advisable.
Changing the electrical installation will also allow the installation of new wiring and outlets. As many as you want, although it is not convenient to fill the entire house. Of course, you have to carefully plan how many plugs are needed and where to place them.
How to change the installation of a room?
To change the electrical installation of a room or a home or premises, it is best to turn to an electrical professional. Especially in the event that the tubes containing the cables have to be rubbed or replaced. If only the cables need to be replaced, the process is easier.
Therefore, those who have certain notions of electricity and skills in repairs and reforms related to it, can try the change themselves. To achieve this, the first thing to do is, obviously, remove the light in the room or home to be renovated. That is, completely disconnect the current. Then you have to find the connection register box that is responsible for providing light to the room or rooms that are going to be renovated.
This register is usually near the front door. It is a cover, which will generally be painted in the same tone as the wall. Or covered in wallpaper. You have to open it and disconnect the cables that correspond to the area in which you work.
To avoid confusion, they should be properly identified. For example, with colored paper glued to the cable. So they can be identified at a glance. Once this is done, it is time to unscrew and remove all the plugs from their place. You have to do the same with the light switches. It is important, when this is done, that each cable that is detached from those that lead to a socket, is located and identified, to know which is its end in the register box from which all the cables start.
With all the cables loose and identified, it’s time to change the cables. To do this you need to use a cable gland guide, which can be purchased at an electricity store. Take this guide at one end and join it, on the one hand, with the electrical cables that were installed until now. On the other hand, the cables to be installed must be attached to said guide to replace them.
Then you can go through the tube from the hole that gives access to the room’s cables, until you reach the area where the switch or plug is located. There it will have to be connected. It is an operation that must be carried out with care so that the guide does not come loose. If this happens, the cable change process will have to be started again. Once the pass is finished, the operation will have to be repeated with all the cables to be changed.
Connect cables and check that everything works
With all the new cables in place, and connected at the desired points, it is time to connect them to the sockets and switches. Of course, you have to be careful not to leave the cables too tight. If done, they can be released more easily. Therefore, they should be a little loose. Thus, since there will be no tension, it will not come loose.
Now it only remains to repeat the operation in the light register box. Of course, also here we will have to be careful to leave the cable slack on this side. For exactly the same reason that it should not be left taut in the area of the sockets. When all the cables are connected, it’s time to close the lid.
There is only one step left to finish: connect the power. Once this is done, check that all plugs and switches are working properly. In case one does not behave as it should, there will be no other remedy to open the plug or switch on the one hand and the manhole cover on the other.
Once you have verified that the cable is properly connected, has no faults and is plugged in where it should be, you can close the cover again and check if it works. Unless the cable has a defect that cannot be seen with the naked eye, it should work without problems.
