The connection of appliances to electrical extensions is a common practice in many Portuguese houses. With the increase in the number of devices used in everyday life, these extensions have become a practical solution for the lack of available outlets. However, inadequate use of this type of equipment can have negative consequences for both energy consumption and for the operation of certain devices.
According to the Colombian Week website, there are certain appliances that should be linked directly to the outlet, at risk of compromising their performance or even suffering permanent damage. One of the most relevant cases is the refrigerator, which requires constant and stable power supply to function properly.
Unstable voltage, increased risk
According to the same source, when connected to an electrical extension, the refrigerator may be subject to voltage variations, which not only reduces its efficiency but can shorten its service life. The situation gets worse in the case of overloads or ruler failures, which can cause temporary dismissals and impair food conservation.
Also, when the device tries to recover the ideal temperature, the compressor is forced to work with greater intensity, increasing energy consumption.
Adds the publication that this type of failure also represents a risk of safety, as current fluctuations can cause electrical failures or, in extreme cases, fires. For this reason, refrigerators, like other high consumer appliances, should always be tied directly to wall socket.
Similar impact on other devices
The microwave is another device highlighted by the example of equipment that should not be connected to electrical extensions. This device consumes between 600 and 1,200 watts by use, which may generate overload if it is connected to the same ruler with other equipment.
Explains the site that, in case of unstable electrical supply, the microwave may take longer to heat food, which, in turn, increases the operating time and total energy consumption. In addition, frequent overloads can damage the extension or directly affect the components of the device.
The importance of a direct connection
According to the same source, appliances such as frozers, washing machines, dryers and ovens should also follow this rule. We talk about equipment that requires continuous electric current, and any instability can seriously affect its performance.
In short, although useful, electrical extensions should be used with caution. The connection of high consumption devices to these extensions should be avoided not only for energy efficiency reasons, but also for domestic safety reasons.
