Electrical installations: learn how to avoid the most common problems

Electrical installations are quite complex and require technical, theoretical knowledge and total attention to be made. It is not difficult to find cases of people who quickly finish a  renovation  or construction to save on expenses and, later, end up having problems with the installation, for example, which was not done in the best way.

The fact of not  paying attention to the  necessary care , can leave your installation vulnerable to several errors, causing the cost to increase, compromising the security of the property and the good finish of the project. Also, failures can have extremely serious consequences, such as overloading electrical components, which eventually lead to shocks, short circuits and even fires.

To avoid faults in your electrical installation, we have selected the most common problems that occur, explaining why they are harmful to the home and what you can do to avoid them! Keep following and check it out. Good reading!

Installation overhead

Here we have a care that you must take every day. Overloading benjamins, rulers and plugs is certainly one of the most common mistakes made in electrical installations. When you connect several electronics at the same point, you end up increasing the chance of damaging the equipment, of having a short circuit, or even of an accident, such as electric shocks.

Overload can also occur in the electrical circuit. Good examples are electric taps,  air conditioning  and showers, among other devices with greater power, which need to be installed in separate circuits. Therefore, never use the same circuit breaker for different circuits.

Taken near water

It is a fact that you will need plugs in the  kitchen , laundry and bathroom. But it is necessary to have extra attention in these environments. To do so, try to install the outlets with a certain distance from the water sources, since it conducts electricity, so keeping the outlets out of reach will reduce the chances of damaging the equipment and also of electric shocks. Also, avoid handling appliances when your hands are wet.

Lack of installation of the DR (Residual Differential)

The DR device (Residual Differential) is a mandatory component related to the safety of residents. It protects against electric shocks, being decisive in places that can get wet, such as service area, kitchen, bathroom, sauna,  swimming pool  etc. Residual differentials must be highly sensitive.

Flashing lights

When the  lights  are flashing it is a sign that there is a bad electrical connection. You can trace the source of the connection by noting which lights are like this. If all are, you will have to review the panel.

The fix for this problem is work for an electrician. If the flicker is located in only one room, it is usually a loose switch connection or a bad switch. In addition, it is important to check all outlets, as some may be connected to the light circuit.

Shower exchange

Changing the  shower  may seem like a common and simple task, but you need to be careful, as one of the most common mistakes is installing a shower with a power above what the installation can handle. Therefore, it is necessary to carefully check the power of the shower and check if it is equivalent to your current installation.

If you do not have the security to do this service, it is best to seek professional help. Doing this prevents an accident or the shower from burning because you have installed the appliance in the wrong way.

Unbonded wires and cables

Unbonded wires are neither certified nor regulated by ABNT, so they cannot be used, since the material used in making them is completely outside the norms, which can seriously compromise the electrical installation.

Remember that some manufacturers even fake Inmetro's seal, with a false phone and address. It is necessary to be attentive, because the consequence is the heating of the conductors, high electricity bill and loss of  energy .

Hot sockets or switches

Hot outlets are a major safety concern and should be dealt with by a professional immediately, unless it is a temperature regulation switch.

Power surges

This can happen due to the lack of wiring in the home or because of appliances with damaged power lines, for example. Outbreaks are very common and last for a microsecond. However, if your home experiences frequent outbreaks, it ends up damaging equipment that reduces life expectancy.

Therefore, carefully analyze the device that connects to the wiring or home network and try to disconnect low quality devices or panels from the outlet. If the outbreaks do not happen again, your problem is solved. Now, if they do, you should call an electrician as soon as possible.

Leave the sockets unprotected

Children and  pets  end up touching everything inside the house, as they are great explorers, right? Therefore, it is always good for an adult to pay attention so that they do not touch the plugs, but it never hurts to have extra protection. The best thing to do is to install protectors to prevent accidents.

Hire a specialized professional

Never do the electrical installation of your home alone, unless you have a lot of experience and practice or are a professional. It is essential to leave a space in the budget to hire a specialized service, as this will prevent poor work done, extra expenses, headaches in the future, among other more serious problems, such as a fire or a short circuit. Here, the old cliché fits: cheap is expensive!

Electrical installations must always be planned and designed by qualified qualified professionals, who follow established rules of quality and safety. To do this, you can ask for recommendations from good professionals at an electrical supply store or from friends and family.

Don't skimp on buying materials

During a construction or renovation, the professional hired to take care of your electrical installation will request the necessary materials to carry out the work. Therefore, it does not help the specialist to indicate the correct materials and you end up buying similar ones to try to save money.

Remember that you do not have the necessary knowledge to make this change, so this can cause serious problems with the installation. It is always important to save, but the savings cannot affect the quality of your project.

As you could see, there are many types of problems that can occur in electrical installations, after all, we are talking about a job that requires a lot of training, attention and responsibility from the professional. By hiring good electricians, you will avoid risks and ensure proper installation for your home. In addition, it is always important to have home insurance that has  coverage  for possible electrical damage and that has an electrician for emergency services.
